  Process for bio-1,3-butanediol purification from a fermentation broth comprising the following steps: (a) subjecting the fermentation broth to separation; (b) subjecting the product obtained in step (a) to treatment with ion-exchange resins; (c) subjecting the product obtained in step (b) to a first evaporation; (d) subjecting the product obtained in step (c) to a second evaporation; (e) subjecting the product obtained in step (d) to a third evaporation, obtaining purified bio-1,3-butanediol. Said purified bio-1,3-butanediol may advantageously be used for the production of bio- 1,3-butadiene, which in turn may advantageously be used as a monomer or as an intermediate in the production of elastomers and (co)polymers.

  从发酵液中纯化生物1,3-丁二醇的工艺包括以下步骤：(a) 将发酵液进行分离；(b) 将步骤(a)获得的产品经过离子交换树脂处理；(c) 将步骤(b)获得的产品进行第一次蒸发；(d) 将步骤(c)获得的产品进行第二次蒸发；(e) 将步骤(d)获得的产品进行第三次蒸发，得到纯化的生物1,3-丁二醇。这种纯化的生物1,3-丁二醇可有利地用于生产生物1,3-丁二烯，而生物1,3-丁二烯又可有利地用作弹性体和(共)聚合物生产中的单体或中间体。

  A high-purity 1,3-butylene glycol product that is colorless and odorless (or almost colorless and odorless), unlikely to cause coloration and odor over time, and/or unlikely to cause an acid concentration increase over time when the product is left in a state containing water is provided. A 1,3-butylene glycol product containing 1,3-butylene glycol, wherein, after the 1,3-butylene glycol product has been kept at 180°C for 3 hours in air atmosphere, at least one of contents of compounds represented by the following Formula (A) or (B) is less than 8 ppm. In the following formula, R1 to R4 are the same as or different from each other, and each of R1 to R4 is a hydrogen atom, an alkyl group which has from 1 to 4 carbon atoms and may be substituted with a hydroxy group, or an alkenyl group which has from 2 to 4 carbon atoms and may be substituted with a hydroxy group.

  本发明提供了一种高纯度的 1,3-丁二醇产品，该产品无色无味（或几乎无色无味），不易随着时间的推移而着色和产生异味，并且/或者当该产品处于含水状态时，不易随着时间的推移而导致酸浓度增加。一种含有 1,3-丁二醇的 1,3-丁二醇产品，其中 1,3-丁二醇产品在空气环境中于 180℃保持 3 小时后，下式（A）或（B）所代表的化合物中至少有一种的含量小于 8 ppm。在下式中，R1 至 R4 彼此相同或不同，R1 至 R4 各为氢原子、具有 1 至 4 个碳原子且可被羟基取代的烷基或具有 2 至 4 个碳原子且可被羟基取代的烯基。
