摘要
己内酰胺与硫酸二甲酯在不同的条件下反应生成两个同分异构体——O-甲基己内酰亚胺和N-甲基己内酰胺;己内酰胺与硫酸二乙酯在上述相似条件下只能得到O-乙基己内酰亚胺,此外,对上述己内酰亚胺的催化重排进行了研究。
This article reports the results of reactions of caprolactam with dimethyl sulfate and diethyl sulfaterespectively.Two isomers—O-methyl caprolactim and N-methyl caprolactam are obtained through re-actions of caprolactam with dimethyl sulfate in different conditions.In similar manner only one com-pound is obtained through reactions of caprolactam with diethyl sulfate.Besides,the catalytic rear-rangement of the derivatives of caprolactam is discussed.
