966,822. Quaternary ammonium derivatives. CIBA Ltd. Nov. 1, 1962 [Nov. 6, 1961; Jan. 10, 1962], No. 41451/62. Heading, C2C. [Also in Division D1] The invention comprises salts of quaternary compounds which in the form of the free acids correspond to the formula: wherein R represents a C 11-17 unsaturated linear aliphatic hydrocarbon residue, a mixture of such residues or a mixture of such residues with saturated residues, R 1 and R 2 each represent a methyl, ethyl or hydroxyethyl group, X represents a halogen atom and m=1 or 2. The above compounds are prepared by quaternating amino amides of the formula:- with a halogeno-acetic acid and converting the free acids to salts by treatment e.g. with triethanolamine or a further quantity of R is preferably H 3 C-(CH 2 ) 7 -CH=CH-(CH 2 ) 7 - derived from oleic acid. |
