| 摘要: |
| 在密封罐内,利用微波辐射技术,以一水合硫酸氢钠为催化剂,由对羟基苯甲酸和异丁醇快速合成了对羟基苯甲酸异丁酯。最佳反应条件为:醇酸物质的量比为3:1,催化剂用量0.8g,辐射时间10min,微波辐射功率522W。在此反应条件下,产品收率基本稳定在96%以上。 |

| Abstract: |
| In sealed Jar,the isobutyl p-hydroxybenzoate was synthesized fastly with the technique of microwave radiation and sodium bisulfate monohydrate as catalyst.Actors in fluencing yield were discussed.The optimum reaction conditions were as follow:molar ratio of alcohol and acid was 3:1,the amount of catalyst was 0.8g,the power of microwave was 522W,the radiating time of microwave was 10min. |
| Key words: isobutyl p-hydroxybenzoate synthesis sealed jar microwave radiation |
