2-甲基-3-丁烯-2-醇合成3-甲基-2-丁烯-1-醇

Synthesis of 3-Methyl-2-butene-1-ol from 2-Methyl-3-butene-2-ol

[目的]2-甲基-3-丁烯-2-醇是异戊二烯间接皂化法生产3-甲基-2-丁烯-1-醇过程中产生的副产物,废物回收再利用是节能减排的有效措施。[方法]2-甲基-3-丁烯-2-醇经氯化、酯化和皂化得到3-甲基-2-丁烯-1-醇。[结果]结果表明:在优化条件下,氯化反应的产率可达87.25%,酯化和皂化反应的产率可达84.53%。[结论]该方法是2-甲基-3-丁烯-2-醇再利用的有效方法。

2-methyl-3-buten-2-ol is a by-product from production of 3-methyl-2-buten-1-ol using method of isoprene indirect saponification.Waste recycling is an effective energy saving measure.[Methods] 3-methyl-2-buten-1-ol was obtained by chlorination,esterification and saponification from 2-methyl-3-buten-2-ol.[Results] The results indicated that chlorination yield was 87.25% and esterification and saponification yield was 84.53% under optimal conditions.[Conclusions] The method is an effective method of reusing 2-methyl-3-buten-2-ol.
