Process for producing unsaturated quaternary ammonium salt |
| abstract |
An unsaturated quaternary ammonium salt represented by the formula ##STR1## WHEREIN R 1 is hydrogen atom or methyl group and R 2 and R 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 1 , R 2 and R 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. |
