| 摘 要： | 丁二酸酐和正丁醇在无催化剂参与下，直接醇解生成丁二酸正丁单酯。用IR谱和MS谱分别对产物进行了结构表征。反应讨论了物质的量比、反应时间对醇解反应的影响。当酸酐与醇的物质的量比为1：3，反应2h时，酸酐醇解率已达到95．8％；反应2．5h以上时，酸酐完全醇解，并且有少量丁二酸二丁酯生成。

| Abstract: | Alcoholysis of succinic anhydride and n - butyl alcohol takes place without catalysts and the monobutyl succinie forms. The IR and MS spectra of the products are measured respectively. The factors such as the molar radio between succinic anhydride and n - butanol, raction time are discussed. The radio of succinic acid to n - butanol is 1：3 ,the reaction time is 2h, alcoholysis radio is up to 95.8% ;the reaction time is over 2.5h,succinic anhydride has been alcoholyzed and a little amount of dibutyl has formed. |
