ABSTRACT:
A process for preparing certain quaternary ammonium compositions from tertiary amines selected from the group consisting of tertiary amines containing one or two long-chain aliphatic groups, and mixtures thereof, is disclosed. The process comprises reacting the tertiary amine with dimethyl sulfate, diethyl sulfate, or trimethyl phosphate. The reaction is performed in a reaction medium selected from the group consisting of compounds which have a melting point below about 100.degree. C., preferably are capable of dissolving the desired quaternary ammonium compound, and which contain either (i) an ester linkage derived from a fatty acid, (ii) a primary hydroxyl group, or (iii) both, and mixtures of said compounds. The reaction typically is performed at a temperature between about 50.degree. C. and about 150.degree. C., for a length of time sufficient to convert at least a portion of the tertiary amine to the desired quaternary ammonium compound.
