摘要: 以苯酚为原料,经磺化脱水和低温相转移催化反应合成了4,4′双甲基丙烯酰氧基二苯砜(BPSDMA)。通过对温度、原料物质的量的比、溶剂和阻聚剂种类等反应因素的考察,得到了合成BPSDMA的较佳反应条件:缩合反应温度160 ℃,苯酚与硫酸的物质的量的比为1∶06;选择二氯甲烷作溶剂,以对甲氧基苯酚为阻聚剂,4,4′二羟基二苯砜与甲基纤维素的物质的量的比为1∶22。该反应条件温和,操作简单,并且目标产物总收率(671%)较高。产物的结构通过IR,1H NMR和GCMS进行了验证。

Abstract: 4,4′Bismethacryloyloxydiphenylsulfone was synthesized using phenol as starting material by sulfonated dehydration and low temperature phasetransfer catalysis reaction. The optimum conditions were obtained by examining the effects of temperature, molar ratio of raw materials, solvent and inhibitor on product yield: The temperature of condensation reaction 160 ℃ and n(phenol) ∶ n(H2SO4) =1∶06; methylene chloride as solvent, 4methoxyphenol as inhibitor and n(BPS)∶n(MC)=1∶22. The results shows that the reaction conditions were moderate and has high yield(671%). The structure of product was characterized by IR, 1H NMR and GCMS.
