    • 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.
    • 由式(Ⅰ)表示的不饱和季铵盐是氢原子或甲基,R 2和R 3各自是甲基或乙基,以高质量的结晶形式,以良好的收率通过使不饱和叔胺反应 其中R1,R2和R3具有与上述相同的含义,与甲基氯在乙腈存在下用作反应溶剂。 由此获得的不饱和季铵盐是可用作生产絮凝剂,抗静电剂,土壤调理剂等的原料的物质。
