Abstract:
A process for preparing a quaternary carboxylic acid ethanolamine ester halide having a melting point of at most 80.degree. C. and having the formula (1): ##STR5## wherein RCO is an aliphatic acyl radical having 8 to 18 carbon atoms,R.sup.2 is a C.sub.3 to C.sub.6 -alkyl radical,R.sup.3 is a C.sub.3 -C.sub.6 alkyl radical, andX.sup.- is halogen,said process comprises quaternizing a carboxylic acid ethanolamine ester with a quaternizing agent consisting of methyl halide,said carboxylic acid ethanolamine ester has the formula (2) ##STR6## wherein RCO is an aliphatic acyl radical having 8 to 18 carbon atoms,R.sup.2 is a C.sub.3 -C.sub.6 alkyl radical, andR.sup.3 is a C.sub.3 -C.sub.6 alkyl radical,said quaternizing is carried out in the absence of organic solvents other than water,or in the presence of water, or in the presence of mixtures of water and low alkanol.
