一种2,5-二氨基苯乙醇的合成方法
摘要：
本发明公开了一种2，5-二氨基苯乙醇的合成方法，该方法以邻硝基甲苯为起始原料，经过羧基化、乙酰化、硝化、酯化、还原、水解、氢化等工序，最后与硫酸成盐而制得。此工艺路线具有原材料简单易得，反应条件温和，收率高且稳定、成本低、操作简单等优点，适合工业化生产。
摘要（英）：

The invention discloses a synthesis method of 2,5-diamino benzene ethanol, which takes ortho-nitrotoluene as a starting material, and 2,5-diamino benzene ethanol is obtained by the processes of carboxylation, acetylation, nitration, esterification, reduction, hydrolyzation, hydrogenation and the like and the process of salifying with sulfuric acid finally. The process route has the advantages of easily obtained raw materials, mild reaction condition, high and stable yield, low cost, simple operation and the like, thereby being applicable to industrial production.
