METHOD FOR RECOVERING 1,3-BUTADIENE AND METHYLETHYLKETONE FROM DEHYDRATION PRODUCTS OF 2,3-BUTANEDIOL

摘要

The present invention relates to a method for collecting 1,3-butadiene and methyl ethyl ketone from dehydrating products of 2,3-butanediol. According to one embodiment of the present invention, disclosed is a method for collecting 1,3-butadiene and methyl ethyl ketone with high purity by effectively and respectively separating the 1,3-butadiene and the methyl ethyl ketone from other by-products or impurities, wherein the 1,3-butadiene and the methyl ethyl ketone are target compounds from the dehydrating reaction products of 2,3-butanediol.
