Abstract: The best technology of sodium cyclamate processing was discussed. The result showed that: amidosulphonic acid, cyclohexylamine and light oil were mixed by the ratio of 1: 2. 5: 3. 5, reacted about three hours under the temperature of 165℃. The crude product was recrystallize, the yield was about 97. 5 percent. Light oil and the residued cyclohexylamine were recovered through the vapour distillation.
