Title (EN) PROCESS FOR PRODUCING 2,3-BUTANEDIOL
(FR) PROCÉDÉ DE PRODUCTION DE 2,3-BUTANEDIOL
(JA) 2,3-ブタンジオールの製造方法
Abstract: front page image
(EN)2,3-butanediol of high purity and very low degree of coloration can be obtained by adding an alkaline substance and conducting distillation (step B) after a step (step A) in which 2,3-butanediol culture broth produced by microbial fermentation is subjected to nanofiltration treatment and ion-exchange treatment.
(FR)Selon l'invention, le 2,3-butanediol est de pureté élevée et un très faible degré de coloration peut être obtenu par l'ajout d'une substance alcaline et la mise en œuvre d'une distillation (étape B) après une étape (étape A) dans laquelle le bouillon de culture de 2,3-butanediol produit par fermentation microbienne est soumis à un traitement de nanofiltration et un traitement d'échange d'ions.
(JA) 微生物の発酵により生産された2,3-ブタンジオール培養液をナノ濾過膜処理およびイオン交換処理する工程(工程A)の後にアルカリ性物質を添加して蒸留する(工程B)ことで、高純度かつ着色度が著しく低い2,3-ブタンジオールを得ることができる。
