| 摘 要：以甲基烯丙基氯為原料，在高濃度醋酸鈉存在下，經(jīng)過(guò)酯化-水解法合成了甲基烯丙醇。以甲基烯丙醇的收率為指標，對反應條件進(jìn)行了優(yōu)化：在n（醋酸鈉）∶n（甲基烯丙基氯）=7∶1、反應溫度為110 ℃、反應體系pH為10.5、反應時(shí)間為5 h的優(yōu)化條件下，甲基烯丙醇收率為88.7%。反應結束后，高濃度的醋酸鈉使產(chǎn)物甲基烯丙醇更容易與水相分離，同時(shí)副產(chǎn)物氯化鈉能自動(dòng)結晶析出，且反應液中的水相可循環(huán)套用，從而顯著(zhù)提高了生產(chǎn)效率，并降低了生產(chǎn)能耗，適合工業(yè)化生產(chǎn)。 |

| Abstract：Using methallyl chloride as raw material, methallyl alcohol was synthesized by esterification-hydrolysis reaction in the presence of high concentration of sodium acetate. Taking the yield of methallyl alcohol as indicator, the reaction conditions were optimized as follows: the molar ratio of NaAc to methallyl chloride was 7∶1, the reaction temperature was 110 ℃, and the pH was 10.5. After 5 hours of reaction under these conditions, the yield of methallyl alcohol reached 88.7%. Because of the presence of high concentration of NaAc, methallyl alcohol was easier to separated and the by-product NaCl could automatically be precipitated out, at the same time the water phase containing high concentration of NaAc could be reused, thus significantly improved the production efficiency and reduced engergy consumption. The whole process is suitable for industrial production. |
