Document Type and Number:
Japanese Patent JPH072819
Kind Code:
A
Abstract:
PURPOSE: To provide a method of purification enabling producing high-purity glycidol of high thermal stability with the investment cost limited to a minimum.
CONSTITUTION: In conducting a purification of crude glycidol subjected to removing both low-boiling and high-boiling by-products from a glycidol-contg. crude reaction liquor produced by reaction between allyl alcohol and hydrogen peroxide in the presence of a catalyst, a distillation column having a side cut line is used and a side cut column having a theoretical plate number of ≥2 is installed on the side cut line.
