摘　　要：以固体碱为催化剂通过酰胺化反应构建了一种以酰胺为桥链、醇羟基为反应基团的反应型紫外线吸收剂,其结构经1H NMR,MS和FT-IR确证。然后通过对碱性催化剂、反应温度、反应溶剂、摩尔比和反应时间的优化进一步提高反应选择性,最终产品选择性可以达到92.5%,此时关键原料转化率为99.8%。A reactive ultraviolet absorber containing amide as bridge chain and alcohol hydroxyl as reactive group was constructed via the amidation using solid bases as catalysts.The structure of the obtained compound was determined by 1H NMR,MS and FT-IR.Subsequently,several process conditions including the base catalysts,reaction temperature,reaction solvents,molar ratio and reaction time were optimized to further improve the reaction selectivity.
