摘　　要：在甲醛与异丁醛摩尔比为1.0∶1.0,反应5～6h,反应温度为60℃,催化剂三乙胺的用量为异丁醛质量分数的5％时,合成羟基特戊醛,收率95％.羟基特戊醛经纯化,在碱催化作用下,经缩合反应,得到羟基特戊酸新戊二醇单酯（HPN）,缩合反应的最优条件为：氢氧化钠的量占反应体系的2％,90℃下反应2h,HPN的收率为78.1％.HPN在强酸型离子交换树脂的催化作用下,与丙烯酸反应,生成羟基特戊酸新戊二醇单酯二丙烯酸酯.The molar ratio of formaldehyde and isobutyraldehyde was 1.0 ∶ 1.0,reaction for 5 to 6 h,temperature was 60 ℃,the dosage of the catalyst triethylamine accounted for 5％ of the mass fraction of isobutyraldehyde,catalytic synthesis of 5-hydroxyvaleraldehyde,the yield was 95 ％.The 5-hydroxyvaleraldehyde purification,then in basic catalyst by one＇ s own condensation for hydroxyl pivalic acid neopentyl glycol monoesters （HPN）,the condensation reaction of the optimal conditions for NaOH 2％ of reaction system,90 ℃ for 2 h,HPN yield was 78.1％.Finally,synthetize hydroxyl pivalic acid neopentylglyeol monoester-two acrylate of strong acid-ion exchange resins with HPN and acrylic acid catalytic reaction.
