摘要
研究了环己基氨基磺酸钠(甜蜜素)的合成工艺条件,结果表明,当氨基磺酸、环己胺和轻油的物料比为1∶2.5∶3.5,反应时间3h,反应温度165℃时,粗产品经重结晶产率可达97.5%。轻油和残余的环己胺可通过水蒸气蒸馏回收,结果满意。
The technological conditions for synthesizing sodium cyclamate were studied.The satisfactory results showed that the productivity could reach 975% when aminosulphonic acid,cyclohexylamine and light oil were mixed at the ratio of 1∶25∶35,reacted about three hours at the temperature of 165℃ and the crude product was recrystallized.Besides,light oil and the residual cyclohexylamine were recovered through the steam distillation.
