【摘要】 本文系统研究了全氟己基乙基甲基丙烯酸酯（C6氟酯）的催化调聚体系及阻聚体系的反应条件。在催化调聚体系中,当催化剂为复合催化剂铜粉+4-甲基吡啶,反应温度介于120～130℃,四氟乙烯与五氟碘乙烷的摩尔比为1:4时,产物中6碳原子的氟碳链含量多、分子量分布窄、调聚转化率高。在阻聚体系中,复合阻聚剂ZJ-701+MQ的阻聚效果最好。当复合阻聚剂ZJ-701与MQ质量比为1:3,浓度为350 mg·kg^-1时,C6氟酯的转换率最小,阻聚效果也最好。对催化调聚体系和阻聚体系反应条件的优化,显著提高C6氟酯的产率,降低了原材料的消耗成本。该工艺路线易操控、成本低廉且转化率高,有利于工业生产。更多还原

【Abstract】 This article systematically studied the reaction conditions of the catalytic telomerization system and polymerization inhibition system of perfluorohexylethyl methacrylate（C6 fluoroester）.In the catalytic telomerization system,when the catalyst was a composite catalyst of copper powder with 4-methylpyridine,the reaction temperature was between 120～130 ℃,and the molar ratio of tetrafluoroethene to pentafluoroiodoethane was 1:4,the content of fluorocarbon chain of 6 carbon atoms in the product was more,the molecular weight distribution was narrow,and the telomerization conversion rate was high.In the polymerization inhibition system,the composite inhibitor ZJ-701 with MQ had the best polymerization inhibition effect.When the mass ratio of composite polymerization inhibitor ZJ-701 to MQ was 1:3 and the concentration was 350 mg·kg^-1,the conversion rate of C6 fluoroester was the smallest,and the polymerization inhibition effect was also the best.The optimization of reaction conditions for catalytic polymerization and polymerization inhibition systems significantly improved the yield of C6 fluoroester and reduced the consumption cost of raw materials.This process route was easy to operate,cost-effective,and had a high conversion rate,which was conducive to industrial production.更多还原
