Abstract: | Taking pyromellitic dianhydride and thionyl chloride as raw key material, 2,5-bis(methoxycarbonyl)terephthaloyl chloride was synthesized. Chlorine determination method was introduced to indicate its purity. The melting point equipment, IR and ^1H NMR techniques were used to characterize the product. The results showed that the purity of 2,5-his (methoxycarbonyl)terephthaloyl chloride was synthesized. |
