ABSTRACT:
An unsaturated quaternary ammonium salt represented by the formula ##STR1## WHEREIN R.sub.1 is hydrogen atom or methyl group and R.sub.2 and R.sub.3 each are methyl or ethyl group, is obtained in high-quality crystalline form in a good yield by reacting an unsaturated tertiary amine repesented by the formula ##STR2## wherein R.sub.1, R.sub.2 and R.sub.3 have the same meanings as defined above, with methyl chloride in the presence of acetonitrile used as reaction solvent. The unsaturated quaternary ammonium salt thus obtained is a substance useful as starting material in the production of flocculants, antistatics, soil conditioners, etc.
