| abstract | 553,681. Quaternary ammonium salts ; proofing textiles ; frothing agents. GEIGY AKT.-GES., J. R. Nov. 29, 1941, No. 15407. Convention date, Nov. 30, 1940. Sample furnished. [Classes 2 (iii) and 15 (ii)] [Also in Group VIII] Quaternary ammonium compounds are obtained by reacting tertiary aliphatic or heterocyclic amines with compounds having the formula wherein X is hydrogen, alkyl or aralkyl, Y is O or COO and Z is halogen. In examples, pyridine is reacted with the chlormethyl derivatives of 5-octadecyloxymethyl-2-hydroxybenzoic acid, 2-octadecyloxymethyl-4-chlorphenol and 4-octadecyloxymethylanisol. The ether and ester starting materials are prepared from the corresponding chlormethyl derivatives and compounds having the formula HYC 15/18 H 31/37 . The resulting intermediates are then heated with formaldehyde and hydrogenhalide. Tertiary amines mentioned are quinoline, monoalkylpiperidines and trimethylamine. The products, which form froths in aqueous solution are used for rendering textiles water repellent, by treating the latter with aqueous solutions of the products and heating. A sample has been furnished under Sect. 2 (5) which is prepared by treating trimethylamine with the chlormethyl derivative of an ester obtained by condensing sodium stearate with 5-chlormethyl-2-hydroxybenzoic acid. The Specification as open to inspection under Sect. 91 comprises also the treatment with tertiary amines of phenols and ethers having the above formula in which Y is a bivalent residue such as NH, NHCO and NHCONH, and additional examples use chlormethyl derivatives containing a carboxyamide residue. This subject-matter does not appear in the Specification as accepted. |
