摘要： Methacrylates containing fluorine are prepared by reacting methacrylic acid, anhydride, acid chloride or methyl ester, with a primary or secondary saturated alcohol which contains 2, 3 or 4 carbons, one hydroxyl group and at last one fluorine atom not attached to the same carbon atom as the hydroxyl group and no other substituents, preferably in the presence of a strong acid and also a substance which inhibits polymerization such as pyrogallol, hydroquinone or tannic acid. The water, hydrogen chloride or methyl alcohol formed during the reaction may be removed, for example, by evaporation. The products of the invention may be polymerized alone or with other polymerizable materials, dyes, plasticisers or polymerization inhibitors. In the examples: (1) 2 : 2 : 2-trifluoroisopropanol, methacrylyl chloride and hydroquinone are reacted together to give trifluoroisopropyl methacrylate which is polymerized by means of heat in the presence of benzoyl peroxide; (2) trifluoroethyl methacrylate is prepared from 2 : 2 : 2-trifluoroethanol, methacrylyl chloride and pyrogallol and is polymerized as in (1); (3) fluoroethyl methacrylate is prepared from monofluoroethanol, methacrylyl chloride and pyrogallol and polymerized as above. The preferred polymerization catalysts are lauryl-, succinic-, benzoyl-, ethylhydrogen-, acetone- or diethylperoxides, benzoin, diacetyl or uranyl acetate and nitrate.

摘要： b -Nitroethylethers are prepared by reacting nitroethylene with alcohols. Preferably, the nitroethylene is prepared in situ by the process of Specification 572,803 by treatment of 1 : 2-dinitroethane or b -nitroethylnitrate with an alcohol. In examples, dinitroethane or b -nitroethylnitrate is heated with methyl, ethyl, benzyl, n-propyl, isopropyl, n-butyl and amyl alcohols, the corresponding b -nitroethylethers being produced directly together with nitrites. The latter and excess alcohols are removed by distillation.

摘要： 238,729. Holroyd, R. Aug. 23, 1924, [Convention date]. Printing - surfaces; type-bars. - A device for use in association with perforating-rules 8 in platen printing or embossing machines, and adapted to engage the sheet of paper to be perforated, comprises a rule or strip 1, 2 adapted to be set in a forme parallel to the perforating - rule and having its bearing surface resiliently supported at a height not less than the height of the cutting edge of the rule. The device consists of two pieces 1, 2 forced apart by a spring 5, disconnection being prevented by the engagement of lugs 6, 7 on the two parts. The perforating- rule 8 is set up between two of the devices 1, 2, Fig. 7, which may be separated from the adjacent type 10 in the forme by brass or other metal plates 9. The surface of the part 1, being normally above the cutting edge of the perforator, engages and holds the sheet of paper before and during the perforating, and also prevents the inking-roller from contacting with the perforator. The part 1 is made of slightly less thickness and length than the part 2 so that it can move freelv in the forme. The devices may be made of standard lengths so that multiples may be used if required. The face of the part 1 may be formed so as to print a line of dashes.

摘要： Glutaric acid is produced by reacting d -hydroxy valeric aldehyde or its isomer 1 : 5-epoxy pentanol-5 or mixtures thereof with nitric acid, the concentration of which is at least 20 per cent by weight of the free nitric acid plus water in the mixture, the temperature during the reaction being maintained below 30 DEG C. after the reaction is initiated. The crude d -hydroxy valeric aldehyde obtained by the hydration of dihydropyran in the presence of acids may be used. To initiate the oxidation reaction, a higher temperature such as 60 DEG C. may be employed; the initiation may be facilitated by adding a nitrite such as sodium nitrite or a portion of the crude product of a previous oxidation (containing oxides of nitrogen). Examples describe the oxidation in the presence of sodium nitrite.

摘要： a -Nitro-iso-butene is obtained by heating 1 : 2-dinitro-iso-butane with an aliphatic alcohol. A lachrymatory oil is obtained. 1 : 2-Dinitro-iso-butane is prepared by passing isobutene into a solution of nitrogen-tetroxide in dry methylated ether. It is recovered by washing with water, after removing excess ether and nitrogentetroxide, and crystallising from methanol.

摘要： A crude 1 : 2-dinitroethane reaction product obtained from ethylene and nitrogen tetroxide according to the processes of Specifications 572,949 and 575,604 is mixed with water or water p and an aromatic hydrocarbon liquid and the mixture allowed to form two layers. b -Nitroethylnitrate is then recovered from the non-aqueous layer by distillation and b -nitroethanol extracted from the aqueous layer by means of a solvent such as ether. It is desirable to remove the 1 : 2-dinitroethane before recovery of the other products. This may be done merely by precipitation by cooling or by adding an organic hydrocarbon and cooling. Solvents such as acetone, ether or methyl or ethyl alcohol may be used, but in this case after separation of the precipitated 1 : 2-dinitroethane, they are removed by distillation. It is also desirable to remove nitrogen oxides, nitrous acid and nitric acid, for example by blowing air through the crude product before treatment, and also to add alkali to the aqueous layer to depress the solubility of the b -nitroethylnitrate therein. Detailed examples are given.

摘要： Nitroethylene, which has a lachrymatory odour, is obtained by reacting an alcohol with 1 : 2-dinitroethane and/or b -nitroethylnitrate, the product being distilled off with the excess alcohol, which is rapidly cooled. Alcohols mentioned are methyl, ethyl, propyl, amyl, allyl and benzyl alcohols, cyclohexanol and esters of glycollic acid. The nitroethylene polymerizes in the presence of alkali, such as ammonia, caustic soda and potash, sodium ethoxide, alkali carbonate and bicarbonate, and calcium and barium hydroxide. Ammonia or a lower alkylamine placed in the receiver for the nitroethylene causes the latter to polymerize. In examples, ethanol is reacted with 1 : 2-dinitroethane and b -nitroethylnitrate in a three-necked flask made of glass sold under the Registered Trade Mark "Pyrex."

摘要： 1 : 5-Pentanediol is prepared by treating d -hydroxyvaleric aldehyde or its isomer 1 : 5-epoxy pentanol-5 with hydrogen at elevated temperatures and/or pressures in the presence of a hydrogenating catalyst. The reaction may be carried out in the liquid phase and in the presence of water. Suitable catalysts are the metals of group VIII or copper which may be supported on an inert carrier. In the examples, hydrogen, d -hydroxyvaleric aldehyde and a nickel on kieselguhr catalyst are reacted together (1) in the absence of water, (2) with water, to give 1 : 5-pentanediol, with some dihydropyran. d -Hydroxyvaleric aldehyde is prepared by hydrating dihydropyran in the presence of a mineral acid.
