弱酸性艳红10B的合成研究

The Synthesis of Tracid Brilliant Red 10B

本文介绍了一种新的合成弱酸性艳红10B的方法。通过改善2,4-二(邻甲苯氧基)苯胺的重氮化和偶合条件,使染料的色光比标准鲜艳0.8以上,染料收率较原来提高24.5%。

A novel synthesis method of Tracid Brilliant Red 10B was introduced.By changing the diazotization conditions of 24-bis（o-tolyloxy）aniline and coupling conditions,the shade of the dye was brighter（DC0.8）than that of the standard,the dye yield increased 24.5% than that of the original.
