三乙胺催化合成2-羥丙基甲醚 |
| 蘇秋芳(茂名學(xué)院; 廣東茂名) |
| 摘 要：以三乙胺為催化劑,環(huán)氧丙烷和甲醇為原料合成2 羥丙基甲醚。較適宜的工藝條件為反應初始壓力0 1MPa;反應溫度:80±5℃,CH3OH∶C3H6O=4∶1(mol);反應時(shí)間3h;三乙胺用量為環(huán)氧丙烷質(zhì)量的4%,環(huán)氧丙烷的轉化率可達95%,2 羥丙基甲醚的選擇性可達91%以上。催化劑可回收循環(huán)使用。 |

| Synthesis of 1-Methoxy-2-propanol with Triethylamine Catalyst |
| SU Qiu-fang （Maoming College; Maoming 525000; China） |
| Abstract：1-Methoxy-2-propanol was synthesized from methanol and 1,2-epoxypropane with triethylamine catalyst.Some influential factors such as reaction temperature,reaction time,propertion of reactants,catalyst amount and beginning pressure of system were discussed.The results showed that triethylamine offered good catalytic activity and selectivity,and the proper technological conditions were established as follows:reaction temperature 80±5?℃,molar ratio of methanol to 1,2-epoxypropane 4∶1,reaction time 3?h,mass rat... |
| Key words：1-methoxy-2-propanol; 1; 2-epoxypropane; methanol; triethylamine |
