摘要
利用糖精废液中的邻磺酰氯苯甲酸甲酯为起始原料,经过酰胺化、脱色、酸析等步骤制得邻苯甲酰磺酰亚胺。车间生产结果表明:所得产品收率达到63.4％,质量分数ω(糖精)=94.9％,实现利润30364.46元/t。该产品可直接生产食用糖精钠。既带来了显著的经济效益,又产生了一定的环境效益。
O-Sulfonylbenzylsuamine is prepared from o-sulfonylchloride methylbenzoate in wastewater of saccharin by miding, decolorizing and acidation et al. The result of production shows that the yield can get 63.4%, the purity of product can reach 94.9%, and the profit is 3036.46 yuan/t. The edible saccharin sodium is directly prepared from o-sulfonylbenzylsuamine. It not only brings notable economic benefits, but also produces certain environmental benefits.
