以氨基磺酸为催化剂，对以正丁醛和1，2-丙二醇为原料合成丁醛1，2-丙二醇缩醛进行了研究。较系统考察了醛醇摩尔比、催化剂的用量、反应时间、带水剂诸因素对缩醛反应的影响。实验结果表明，丁醛为0.2mol，n（丁醛）∶n（1，2-丙二醇）=1∶1.5，氨基磺酸1g，带水剂环己烷15mL，反应时间为60min时，产品的收率可达56.14%。
以氨基磺痠為催化劑，對以正丁醛和1，2-丙二醇為原料閤成丁醛1，2-丙二醇縮醛進行瞭研究。較繫統攷察瞭醛醇摩爾比、催化劑的用量、反應時間、帶水劑諸因素對縮醛反應的影響。實驗結果錶明，丁醛為0.2mol，n（丁醛）∶n（1，2-丙二醇）=1∶1.5，氨基磺痠1g，帶水劑環己烷15mL，反應時間為60min時，產品的收率可達56.14%。

Butyraldehyde 1,2-propanediol acetal was synthesized from n-butyl aldehyde and 1,2-propylene glycol using aminosul-fonic acid as catalyst. The effects of aldehyde alcohol morlar ratio,the amount of aminosulfonic acid,reaction time and water carrying on product yield were studied. The optimal reaction conditions were identified as followed:the amount of butly aldehyde was 0.20mol, n(aldehyde):n(1,2-propanediol)=1∶1.5;the dosage of catalyst was 1g,the volume of cyclohexane was 15mL,the reaction time was 60min,and the yield of butyraldehyde 1,2-propanediol acetal could reach 56.14%.
