摘要
以Zn-NH4Cl还原体系为基础进行苯基羟胺合成工艺系统研究,发现少量胺的添加物可以有效抑制羟胺产物继续还原为胺的进程。研究了不同溶剂、酸度对于反应的影响,优选出的工艺体系收率达到72%,较先前报道大幅度提升。
According to the previous reports, reduction system of Zn-NH4Cl was posed and investigated for the synthesis of N-（2-Methylphenyl）-hydroxylamine. It was surprising that coexistence of small amounts of amines remarkably suppressed the subsequent by-reduction from hydroxylamine to amine. Other factors such as solvents, acidity were also surveyed and optimized pledging the pleasant yield of 72%.
