标题:在协同和可持续催化剂上有效合成糖醇
摘要:针对以往报道的催化剂存在糖醇收率低,功能单一,不稳定,活性位点作用有争议等不足,制备了一系列用于糖醇生产的催化剂.结合条件实验和表征详细讨论了每种金属的作用及其协同合作.结果表明,双功能ni 6.66 Fe 1 Al 1.55催化剂结构独特,具有超顺磁性和优异的活性.金属ni的(111)和(200)面是加氢活性相,优先暴露在ni-Al-O X上尖晶石.所需的阿糖醇或甘露醇是通过调整 Brünsted 和 Lewis 酸位点的比率获得的.回收试验表明,所制备的镍基催化剂的独特结构可以抑制浸出和中毒,具有较高的结构稳定性和活性.

摘要:A process for a double stage convergent synthesis of a polymeric polyalcohol substantially and preferably built up from polyester units and composed of a monomeric or polymeric core to which at least one hyperbranched dendritic branch (dendron) consisting of a number of branching generations is added. The branching generations comprise a polymeric or monomeric branching chain extender having three reactive functions of which two are hydroxyl groups and one is a carboxyl group. The two hydroxyl groups of the branching chain extender is in a first step ketal protected by reacting said two hydroxyl groups with a ketal. A second step includes protection of the carboxyl group of said branching chain extender. The ketal protected branching chain extender and the carboxyl protected chain extender are then employed for repeated addition in a number of step yielding a predetermined number of branching generations. The thus synthesized dendron is finally added to a core having reactive hydroxyl or epoxide groups and the ketal protected hydroxyl groups are optionally deprotected.

摘要:The present invention discloses a method for promoting the fermentation of Gluconobacter oxydans to produce D-sorbitol dehydrogenase and pyrroloquinoline quinone. The method comprises: Gluconobacter oxydans is inoculated to a fermentation culture medium, fermented and cultured under the conditions of 28-32° C. and 150-180 rpm for 6-24 hours, the fermented solution is centrifuged, and wet bacteria are collected, thus acquiring bacteria cells containing D-sorbitol dehydrogenase and pyrroloquinoline quinone. The method promotes the synthesis of coenzyme pQQ and the enzyme activity of per unit volume D-sorbitol dehydrogenase, Gluconobacter oxydans cultured and acquired using the method is biotransformed to synthesize miglitol precursor 6-deoxy-6-amino(N-hydroxyethyl)-α-L-furan sorbose (6NSL), the conversion progress of the product 6NSL is increased by 21-35%, and a biotransformation step cycle is reduced from 48 hours to 36 hours. In addition, under a same substrate concentration (60 g/L), the cumulative concentration of the product 6NSL is increased by 10 g/L or more.
