1.Taking pyromellitic dianhydride and thionyl chloride as raw key material, 2,5-bis(methoxycarbonyl)terephthaloyl chloride was synthesized.
化亚矾及均苯四甲酸酐主要原料通过法合成了对位均苯甲酯。
2.Novel controlled releasing polythiourea microcapsules were prepared from terephthaloyl diisothiocyanate and o-phenylenediamine by interfacial polycondensation.
