    • Cellulosic materials such as cotton, jute or linen fabrics, paper, regenerated cellulose, cellulose esters and ethers, e.g. viscose and cellulose acetate are rendered water repellent by treatment with an aldehyde and an amide of a higher fatty acid having at least 10 carbon atoms, or with a pre-formed reaction product of such an amide compound with an aldehyde, and subjecting the treated material, preferably in the presence of an acid substance as catalyst, to the action of dry heat. The treatment may be carried out in the presence of a wax. Example 3 described treating mercerized cotton fabric with an aqueous dispersion made by milling in a ball mill stearohydroxy-ethylamide water and a naphthalene formaldehyde sulphuric acid condensation product prepared as described in Specification 224,077, [Class 1 (i)], and adding sodium dihydrogen phosphate, drying at 30-40 DEG C. and then heating at 120 DEG C. Reference has been directed by the Comptroller to Specification 463,300.ALSO:Cellulosic materials such as cotton, jute, or linen fabrics, paper, regenerated cellulose, cellulose esters and ethers, e.g. viscose and cellulose acetate are rendered water repellent by treatment with an aldehyde and an amide of a higher fatty acid having at least 10 carbon atoms, or with a pre-formed reaction product of such an amido compound with an aldehyde, and subjecting the treated material, preferably in the presence of an acid substance as catalyst, to the action of dry heat. The treatment may be carried out in the presence of a wax. Suitable acid amides are oleyl amide, stearamide, lauramide, lauryl benzamide, stearomethylamide and stearanilide. The reaction product may be stearohydroxymethylamide prepared as described in Specification 475,170. The reagents may be applied simultaneously or successively as solutions in organic solvents such as acetone or as aqueous dispersions. The aldehyde, e.g. formaldehyde or paraformaldehyde may be applied in aqueous solution or as vapour. Suitable acid catalysts are sodium dihydrogen tartrate, tartaric acid and lactic acid; they may be applied before, together with, or after the treatment reagents. Examples describe (1) treating cotton fabric in an acetone solution of stearamide, drying and immersing in aqueous formaldehyde containing sodium dihydrogen phosphate, drying at 30 DEG C. and heating at 130 DEG C.; (2) wetting cotton fabric with an aqueous solution of sodium dihydrogen phosphate, drying, treating with an ethanol or acetone solution of stearohydroxymethylamide or oleyl hydroxymethylamide at 40 DEG C., drying at 30-40 DEG C. and heating at 120 DEG C. Alternatively, the catalyst may be phosphoric acid added to the solution of the amide; (3) treating mercerized cotton fabric with an aqueous dispersion made by milling in a ball mill stearohydroxyethylamide, water and a naphthalene formaldehyde sulphuric acid condensation product prepared as described in Specification 224,077, [Class 2 (iii)], and adding sodium dihydrogen phosphate, drying at 30-40 DEG C. and then heating at 120 DEG C.; (4) impregnating cotton fabric in a warm solution containing paraffin wax dissolved in benzene and methylol stearamide and phosphoric acid dissolved in methylated spirits, drying at 35 DEG C. and then heating at 130 DEG C.

    • Equimolecular proportions of 1 : 6-diamino-6-methyl-heptane and an aliphatic dicarboxylic acid are heated together to give a polyamide. Amide forming derivatives or low molecular weight polymers or the preformed salt may be used. The reactants are heated until filaments formed from a melt of the polyamide can be cold-drawn into fibres. The acids include oxalic; glutaric; adipic; pimelic; suberic; azelaic; sebacic; brassylic; tetradecanedioic; octadecanedioic; p-phenylenediacetic; hexahydroterephthalic and 1 : 3-cyclopentane dicarboxylic acids. The heating, which is usually at from 200 DEG to 300 DEG C. in the presence or absence of solvent or catalyst and preferably in the absence of air or oxygen, is performed under conditions allowing the removal of water, e.g. under reduced pressure, at least during later stages. A mono-functional amide-forming reactant may be used to stop the reaction at any stage as described in Specification 495,790. The products are soluble in methanol and ethanol and may be made into films forming strongly adhesive bonds to glass, metals and similar surfaces. Solutions in water-miscible organic solvents on mixing with water provide stable aqueous dispersions. In an example, a solution of 1 : 6-diamino-6-methylheptane in ethanol is added to an ethanol solution of adipic acid, the white crystalline salt separating out on standing. The salt is heated for 3 hours at 220 DEG C. in a closed vessel, which after cooling is opened and heated at 255 DEG C. for 1 hour at atmospheric pressure and then for 12 hours at 0.3 mms. pressure. The product, which has an intrinsic viscosity of 0.74, softens at 100 DEG C. and can be spun at 165 DEG C. to filaments which may be cold-drawn.ALSO:1 : 6-Di-amino-6-methyl heptane is converted into an aliphatic dicarboxylic acid salt by interacting equimolecular proportions of the amine and adipic acid in ethanolic solutions, the salt crystallizing out on standing. Reference is made to the formation of salts of the amine with other aliphatic dicarboxylic acids, e.g. oxalic, glutaric, pimelic, suberic, azelaic, sebacic, brassylic, tetradecanedioic, octadecanedioic, p-phenylene diacetic, hexahydro-terephthalic and 1 : 3-cyclo-pentane dicarboxylic acids. The salts are starting materials for the production of polymeric amides (see Group IV (a).

[Classes 2 (iii) and 15 (ii)] Water-soluble compounds are obtained by heating together a phenol substituted by one or more hydroxymethyl groups in the o or p positions and a salt of or inorganic acid anhydride addition compound of a heterocyclic tertiary amine. The - products are believed to be quaternary ammonium salts; and may be used as assistants in dyeing cellulose fibres. The phenols used may also contain, as substituents in the nucleus or side chain, halogen atoms, acylamido, acylamidomethyl, alkyl, aralky or hydroxyaralkyl groups ; the hydroxyaralkyl groups may be substituted by further hydroxymethyl groups. The tertiary amine salt may be made in situ, e.g. by passing in hydrochloric acid gas. The reaction may be carried. out under reduced pressure, or-in the presence of solvents or diluents, e.g. toluene. Substituted phenols , specified include mono. or polyhydroxymethyl derivatives of phenol, cresols; p-tert.-butylphenol, dodecylphenol, octadecylphenol, stearamidomethylphenol, p - chlorophenol, diphenylolmethane, di - o - cresylolmethane, diphenylolpropane and di-o-cresytolpropane. These hydroxymethyl derivatives may be prepared by alkaline condensation of the phenols with formaldehyde or paraform aldehyde. The amines specified are pyridine, c-alkyl pyridines and quinoline in the form of halides, sulphites, nitrates, m-nitrobenzene sulphonates, or p-toluene sulphonates or addition compounds with sulphur dioxide or trioxide. In one example, the picrate of the condensation product is referred to, and in another example the product is stated to give an aqueous solution which foams on shaking. According to the second Provisional Specification, formaldehyde, an acid or acid anhydride, a. heterocyclic tertiary base and a substituted phenol may be brought into combination in various ways. The phenol may be treated with aqueous formaldehyde saturated with hydrogen chloride to form hydroxyphenyl-chloromethane, which is then reacted with the amine, or the phenol may be treated with formaldehyde, hydrogen halide and tertiary amine in succession. The use of halogenacylamidophenols, e.g. p - chloracetamidophenol, is referred to. The formaldehyde may be monomeric or polymeric, or may be furnished by substance such as hexamethylene tetramine or formaldehyde-bisulphite.
