摘要： The invention discloses a method for purifying butylene oxide by using an anion exchange resin and an adsorbent. The anion exchange resin removes acid and aldehyde impurities while the adsorbent removes water impurities from the butylene oxide. Depending upon the impurity level, the purification steps can be conducted singularly or in combination, and the process can proceed either batchwise in a reactor or continuously in a column. The ion exchange resin of the choice is a sulfonated macroreticular anion exchange resin and the adsorbent of choice is a molecular sieve.
