• Preparation of glycerol tert-butyl ethers
  申请人：Barsa Edward A.

  公开（公告）日：2009-09-24

  A process for making glycerol di-tert-butyl ethers is disclosed. In one aspect of the invention, glycerol and isobutylene react in the presence of a β-zeolite having a silicon to aluminum ratio greater than 150. In another aspect, the etherification is performed in the presence of a β-zeolite and added tert-butyl alcohol. Each process selectively provides glycerol di-tert-butyl ethers while reducing the generation of isobutylene dimers and trimers. Utilizing both aspects of the inventive process simultaneously affords a diether product mixture containing less than 5 wt. % of isobutylene oligomers.

  揭示了一种制备甘油双叔丁基醚的方法。在发明的一个方面中，甘油和异丁烯在具有硅铝比大于150的β-沸石存在下发生反应。在另一个方面，醚化反应在β-沸石和添加的叔丁醇存在下进行。每种方法都选择性地提供甘油双叔丁基醚，同时减少异丁烯二聚体和三聚体的生成。同时利用这两个创新方法可获得含有少于5 wt.％异丁烯寡聚体的二醚产品混合物。

  The present disclosure is directed to methods and composition used in the preparation of alpha-hydroxy carboxylic acids and esters from higher sugars using a tandem catalyst system comprising retro-aldol catalysts and Lewis acid catalysts. In some embodiments, these alpha-hydroxy carboxylic acids may be prepared from pentoses and hexoses. The retro-aldol and Lewis catalysts may be characterized by their respective ability to catalyze a 1,2-carbon shift reaction and a 1,2-hydride shift reaction on an aldose or ketose substrate.

  本公开涉及使用串联催化剂系统，包括反-醛酸催化剂和Lewis酸催化剂，从较高的糖中制备α-羟基羧酸和酯的方法和组合物。在某些实施例中，这些α-羟基羧酸可以从戊糖和己糖中制备。反-醛酸和Lewis催化剂可通过它们各自在醛糖或酮糖底物上催化1,2-碳迁移反应和1,2-氢迁移反应的能力来表征。
