Method for safely and efficiently increasing separation yield of 3-methyl-3-butene-1-alcohol

The invention provides the method for safely and efficiently improving the separation yield of the 3-methyl-3-butene-1-alcohol. According to the method, the TD24 of the tar after rectification and heavy component removal of the 3-methyl-3-butene-1-alcohol is improved, the safety of rectification operation is enhanced, meanwhile, the content of formaldehyde in the recovered 3-methyl-3-butene-1-alcohol is reduced, and the separation yield of the 3-methyl-3-butene-1-alcohol is improved. 本发明提供了一种安全、高效提升3-甲基-3-丁烯-1-醇分离收率的方法。该方法通过提高3-甲基-3-丁烯-1-醇精馏脱重后焦油的TD24，增强精馏操作的安全性，同时降低回收3-甲基-3-丁烯-1-醇中的甲醛含量，提高3-甲基-3-丁烯-1-醇的分离收率。
