摘　　要：以1,8-二氨基萘、四氯苯二甲酸酐为原料,以AcOH为催化剂,在邻二氯苯中反应合成了溶剂红EG。用正交试验法优化了合成工艺技术条件。在最佳条件下,产品合成收率为98.03%,可以满足热塑性塑料着色的质量要求。Solvent Red EG was synthesized from 1,8-diaminophthalene and tetrachlorophthalic anhydride in odichlorobenzene and in the presence of catalyst acetic acid.The synthesis process was optimized by the orthogonal tests.Under the optimum conditions,the yield was 98.03% and the performances of the product could meet the requirements of a thermoplastic dyeing.
