摘 要:在堿性條件下,氯甲基化聚苯乙烯與丁二酰亞胺反應合成了聚(對乙烯基芐基丁二酰亞胺)樹(shù)脂(簡(jiǎn)稱(chēng)為丁二酰亞胺樹(shù)脂),采用元素分析、紅外光譜對合成樹(shù)脂的組成進(jìn)行了表征。并考察了該樹(shù)脂在酯水解反應中的催化活性。結果表明,在合成反應12 h后,樹(shù)脂增重最多,其中氮含量為4.08 %,殘余氯含量為2.51 %,IR譜圖中1 640 cm-1處出現較強酰胺羰基峰。在催化酯水解反應中,酸收率均大于85 %,且催化穩定性好。 |

Abstract:Poly(p-vinylbenzyl succinimide) resin,which can be abbreviated to succinimide resin,was prepared by the reaction of chloromethylated polystyrene with succinimide in the presence of base. The succinimide resin was characterized by diffuse reflectance infrared Fourier transform spectrometry and elemental analysis. The catalytic activity of the succinimide resin for hydrolysis of esters was studied. Our results indicated that succinimide resin with 4.08 % nitrogen content,2.51% residual chlorine content and maximal value in weight was reached by reacting 12 h,it was found stronger peak of amide carbonyl group in IR spectra at 1 640 cm-1. It showed good catalytic stability in the hydrolysis of esters,yield of acids were all more than 85 %. |
Key words:poly (p-vinylbenzyl succinimide) resin;synthesis;catalysis;hydrolysis of ester |
