Synthesis of Sodium Cyclamate Using R 3N · SO 3 as Sulfonating Agent

用R3N·SO3为磺化剂合成甜蜜素的新工艺研究

The influences of reaction temperature and amount of sulfonating agent on sulfonating reaction were investigated.

考察了反应温度、磺化试剂用量对磺化反应的影响.

the optimum conditions for synthesizing sodium cyclamate by using sulfur trioxide dioxane as sulfonating agent were investigated. the yield of sodium cyclamate is around 94.8% and the purity is more than 98.2%.

以三氧化硫·二氧六环作磺化剂合成甜味素，取得了最佳工艺条件，总收率可达94.8%，产品纯度在98.2%以上。

The results show that the method which synthesize sulfoacetic acid disodium by using chloroacetic acid and ethyl chloroacetate as raw material and sulfite sodium as sulfonating agent by nucleophilic substitution reaction is feasible.

结果表明：以氯乙酸和氯乙酸乙酯为原料采用亲核取代反应合成磺酸乙酸钠是可行的。
