甜味剂环己基氨基磺酸钠合成工艺条件优化

Optimization on synthetic technology condition of sodium cyclamate

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 975% when aminosulphonic acid,cyclohexylamine and light oil were mixed at the ratio of 1∶25∶35,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.
