Abstract

See full text

Disclosed is a method of preparing 1,3-butadiene and methyl ethyl ketone from 2,3-butanediol, including: a) providing a plurality of adiabatic reactors, which include a catalyst bed for dehydrating 2,3-butanediol, without a heat transfer medium, and are connected in series; b) introducing a stream including 2,3-butanediol at a temperature ranging from 200° C. to 400° C. into a first adiabatic reactor among the plurality of adiabatic reactors; c) dehydrating the 2,3-butanediol so as to be converted into 1,3-butadiene and methyl ethyl ketone and discharging a product stream including 1,3-butadiene and methyl ethyl ketone; d) heating the discharged product stream to to 200° C. to 400° C.; and e) introducing the heated product stream into a second adiabatic reactor so that 2,3-butanediol is further dehydrated and converted into 1,3-butadiene and methyl ethyl ketone and then discharging the product stream including 1,3-butadiene and methyl ethyl ketone.
