13- 23- Separation and purification method of 13-propanediol and 23-butanediol from microbial culture media

摘要

The present invention relates to a method for separating and purifying 1,3-propanediol and 2,3-butanediol from a culture medium of microorganisms producing 1,3-propanediol and 2,3-butanediol, Propanediol and 2,3-butanediol are evaporated and sequentially passed through a condenser to conduct dehydration and decontamination simultaneously, followed by separation and purification, and 1,3-propanediol and 2,3-butanediol And a method for separating and purifying the same. By using the separation method according to the present invention, it is possible to obtain high-purity 1,3-propanediol (1,3-propanediol) from a culture solution of a microorganism producing 1,3-propanediol and 2,3-butanediol And 2,3-butanediol can be separated and purified at high efficiency and low cost.
