| titleOfInvention | A separation and purification method of (2S,3S)-2,3-butanediol and its application |
| abstract | The invention relates to the field of chemical technology, and specifically discloses a method for separating and purifying (2S,3S)-2,3-butanediol and its application. The separation and purification of (2S,3S)-2,3-butanediol The purification method is to transport the 2,3-butanediol stereoisomer mixture containing at least (2S,3S)-2,3-butanediol to a reaction vessel, and the output end of the reaction vessel is connected to a fractional distillation column, Separated and purified (2S,3S)-2,3-butanediol is obtained by controlling the temperature of different sections of the fractional distillation column; this method can not only separate the 2,3-butanediol stereoisomer mixture Meso‑2,3‑butanediol and (2S,3S)‑2,3‑butanediol make (2S,3S)‑2,3‑butanediol reach a purity of more than 99% with low cost and high efficiency , takes a short time, solves the problem that the optical purity of (2S,3S)-2,3-butanediol in existing 2,3-butanediol products cannot reach 99wt%, and has broad market prospects. |
