摘要： The invention comprises a mixture of polyethers having a molecular weight of 1000 to 6000 and containing three or more hydroxyl groups which polyethers consist essentially of ethylene oxide and 1:2 propylene oxide residues and the residue of a polyhydric alcohol containing three or more hydroxyl groups, wherein from 4-20% by weight of the alkylene oxide residues are ethylene oxide residues, wherein at least 2% by weight of the alkylene oxide residues are ethylene oxide residues in a nonterminal position separated from a terminal block of ethylene oxide residues by a penultimate block of propylene oxide residues, and wherein from 15 to 50% of the hydroxyl groups present are primary hydroxyl groups. The mixture is prepared by (a) reacting 1,2-propylene oxide and ethylene oxide in turn or together with a polyhydric alcohol having three or more -OH groups, (b) reacting the product of step (a) with 1,2-propylene oxide and (c) reacting the product of (b) with ethylene oxide in an amount such that 15-50% of the -OH groups present are primary. Suitable polyhydric alcohols are glycerol, trimethylol propane, 1:2:6 - hexane triol, pentaerythritol, a -methyl glucoside and sorbitol. The reaction is preferably effected in the presence of an alkali metal catalyst. Polyurethanes are formed by reacting an organic polyisocyanate or polyisothiocyanate of formula R(NCX)n+1, wherein R is an organic radical, X is O or S and n is a positive integer with a mixture of polyethers according to the invention. Water and/or an auxiliary blowing agent may be incorporated into the reaction to form polyurethane foams and foam catalysts and stabilizers may also be present. Alternatively, the foams may be prepared by reacting the polyurethane prepolymer prepared as above with water in the presence of a foam catalyst and a foam stabilizer. The invention also comprises the moulding of polyurethane foams prepared as above.ALSO:A solution of a polyurethane prepolymer is used as a surface coating agent and is applied to wood, metal or leather to give clear top coats or varnishes. The solvent is preferably evaporated from the film applied to the surface to be coated. The polyurethane prepolymer (see Div. C3) is prepared from a mixture of polyethers having a molecular weight of 1000 to 6000 and containing three or more hydroxyl groups which polyethers consist essentially of ethylene oxide and 1, 2-propylene oxide residues and the residue of a polyhydric alcohol having 3 or more -OH groups, wherein from 4-20% of the alkylene oxide residues are ethylene oxide residues, wherein at least 2% of the alkylene oxide residues are ethylene oxide residues in a non-terminal position separated by a penultimate propylene oxide residue block from a terminal ethylene oxide block, and wherein 15 to 50% of the hydroxyl groups present are primary, by reactions with a polyfunctional isocyanate or isothiocyanate, and is cross-linked by the reaction of the terminal isocyanate groups with atmospheric moisture or reactive groups in the substrate.

摘要： Flame-resistant rigid polyurethane foams are prepared by reacting a composition containing esters of phosphorus oxy-acids with polyhydroxy polyoxyalkylene glycol ethers of cyclic sugars, prepared by reacting the sugar or its monohydrate with at least one phosphorus oxy-acid or oxide to form a partial ester of a phosphorus acid and subsequently reacting the partial ester with at least one alkylene oxide selected from ethylene oxide, propylene oxide, epichlorhydrin and butylene oxide (see Division C2) with an organic polyisocyanate, in the presence of a blowing agent, a foam stabilizing agent, and a catalyst system for the foaming reaction. The initial phosphate ester has an acid value of less than 2, a hydroxyl number of more than 280, and a phosphorus content of between 1 and 10% by weight. Polyaryl polyisocyanates are preferred, and the catalyst may be a tertiary amine and/or a tin salt or an organo-tin compound, and an aliphatic halogenated alcohol may be present in the reaction mixture.ALSO:Compositions containing esters of phosphorus oxy-acids with polyhydroxy polyoxyalkylene glycol ethers of cyclic sugars are prepared by reacting the sugar or its monohydrate with at least one phosphorus oxy-acid or phosphorus oxide to form a partial ester of a phosphorus acid and subsequently reacting the partial ester with at least one alkylene oxide selected from the group consisting of ethylene oxide, 1-2 propylene oxide, epichlorhydrin and butylene oxide, whereby a mixture of hydroxy compounds is formed having an acid value of less than 2, a hydroxyl number of more than 280, and a phosphorus content of between 1 and 10% by weight, both of said reactions being carried out in a polar solvent which is substantially non-reactive with regard to the sugar, the alkylene oxide and the phosphorus oxy-acid or oxide. Specified cyclic sugars are sucrose, glucose, manrose, arabinose, fructose and a -methyl glucoside, and specified oxy-acids and oxides of phosphorus are H3PO4, H4P2O7, H6P4O13 and P2O5. The phosphoric acid may be used in the ratio of one to three moles for every mole of sugar, and this reaction is preferably carried out between 40 DEG and 100 DEG C. The product is a mixture of partial esters having on average about one phosphate group per sugar molecule. This is then reacted with the alkylene oxide, e.g. at 80 DEG to 100 DEG C. In a modification of the process the sugar is first reacted with the alkylene oxide and the products thereafter reacted with the phosphorus oxy acid or oxide to form the partial ester. The product preferably has an average of 4 to 8 hydroxy groups per molecule and a viscosity of less than 20,000 centipoise at 25 DEG C. Suitable solvents for the preparation of the partial ester are dimethyl dioxane, triethyl phosphate or tri-(chloroethyl) phosphate, but preferably dioxane or dimethyl formamide are used for both stages of the reaction. The compositions are used in the making of polyurethane foams (see Division C3).

摘要： Ethylene oxide containing acetaldehyde as impurity is purified by continuously passing the ethylene oxide in admixture with an alkali metal glycolate dissolved in a quantity of a polyoxyalkylene glycol of molecular weight between 100 and 700 sufficient to render the reaction mixture homogeneous in the liquid phase but not in excess of 5 per cent by volume of the ethylene oxide (as liquid), through a reactor whose internal temperature is maintained between 0 DEG and 180 DEG C., under a pressure sufficient to maintain the reaction mixture in the liquid phase, the reaction conditions including concentration of glycolate and contact time being so chosen that not more than 5 per cent by weight of the ethylene oxide is reacted, and recovering purified ethylene oxide from the product. In the preferred process, the alkali metal glycolate is the sodium, potassium or lithium glycolate of the glycol solvent, the glycol has a molecular weight of about 400, the temperature is between 30 DEG and 100 DEG C., the pressure between 100 and 2000 lbs. per square inch, the alkali-metal concentration between 0.010 and 0.025 gm. atoms per litre of reaction mixture, the volume ratio of glycol to ethylene oxide from 1 to 20-100 and the contact time about 1 to 120 minutes, especially 20 or less minutes. An acetaldehyde content of 0.67 per cent may thereby be reduced to 0.048 or less. Examples are given wherein, using illustrated apparatus (not shown), ethylene oxide and glycol solution containing sodium glycolate are separately pumped into a mixing device from which the mixture passes to a 72 ft. tubular reactor of 0.154 inch bore maintained at about 95-100 DEG C. and provided at its exit with a pressure let-down valve allowing the desired pressure to be maintained in the reactor; the reaction product then passes to a still operated under normal pressure wherein purified ethylene oxide is distilled off and the residue passed to waste. Specification 736,991 is referred to. According to the Provisional Specification, the purification is effected by means of any basic material dissolved in a sufficient quantity of organic hydroxy compound to render the reaction mixture homogeneous in the liquid phase and is restricted to use of a contact time of between 1 and 120 minutes. Specified organic hydroxy compounds are methanol, ethanol, ethylene glycol, diethylene glycol, any polyoxyethylene glycol and a polyoxypropylene glycol.

摘要： A polyurethane is prepared by the reaction of a stoichiometric excess of a di- or higher functional organic isocyanate with a mixture of one or more monohydric alcohols and one or more polyoxyalkylene polyols which contain more than two hydroxyl groups. The polyol is preferably a triol and preferably prepared from propylene oxide and a trihydric alcohol, e.g. glycerol, trimethanol propane, hexane triol. The monohydric alcohols may be represented by the formula R(OCnH2n)yOH where R is a hydrocarbon radical, n may be 2, 3 or 4, and y may be 0 or an integer between 1 and 50. Compounds mentioned are the condensation products of ethylene oxide with cetyl-oleyl alcohol and ethylene oxide with nonyl phenol. The isocyanate may be aromatic or aliphatic. The mixture of alcohols may also contain a polyoxyalkylene diol which may be the reaction product of propylene oxide with water or a dihydric alcohol, e.g. propylene glycol and preferably has a M.W. of 1000-3000. The polyurethane may be dissolved in a solvent, e.g. an ester, ketone or hydrocarbon fraction and used for coating leather. Up to 100% of raw oil, e.g. cold test neatsfoot oil or sperm oil may be incorporated in the solution. In Example (1) a mixture of glycerol based polyoxypropylene triol, cetyl-oleyl alcohol and polyoxypropylene diol were reacted with tolylene diisocyanate and the polymer dissolved in Shellsol "A." In other examples, the monohydric alcohols used were (1B) condensate of nonyl phenol and ethylene oxide, (1C) anhydrous butanol, (2) cetyl-oleyl alcohol, (11) a butoxy polyoxypropylene monohydric alcohol.ALSO:A solution of a polyurethane in an aromatic hydrocarbon fraction, ketone or carboxylic ester is applied to leather, said polyurethane having been prepared by reacting a mixture of one or more monohydric alcohols and one or more polyoxyalkylene polyols which contain more than two hydroxyl groups with a stoichiometric excess of a di or higher functional organic isocyanate. The urethane solution may be applied by a paint roller or by spraying or padding. Leathers mentioned are: shoe upper leather, full chrome goatskin, pigskin, sheepskin, upholstery and case leathers. In a typical example (II) a mixture of a polyoxypropylene triol and a butoxy polyoxypropylene monohydric alcohol were reacted with toluene diisocyanate in shellsol "A" and the polymer solution appled by spraying to the grain side of chrome upper shoe leather, the solvent allowed to evaporate and the treated leather finished by coating with a pigment and an acrylic resin emulsion followed by a spray coat of nitrocellulose emulsion and finally by a tinted spray coat of high flash nitrocellulose lacquer.
