A catalyst don’t appear in the overall stoichiometry of the reaction it catalyzes, but it must appear in at least one of the elementary reactions in the mechanism for the catalyzed reaction. 10343-06-3, Name is 2,3,4,6-Tetra-o-acetyl-D-glucopyranose, molecular formula is C14H20O10. In a Patent£¬once mentioned of 10343-06-3, category: Tetrahydropyrans
A glycal of preparation method (by machine translation)
The invention belongs to the technical field of chemical industry, discloses a glycal of the preparation method. The method: (1) under the nitrogen atmosphere, the organic solvent is added with multiple hydroxyaldehydes monosaccharide and catalyst in the reactor, adding hydroxyl protective agent, reflux reaction, follow-up processing, to obtain compound a; (2) under the condition of the nitrogen, the ammonium salt and an organic solvent are the compound is added in a reaction, the follow-up treatment, to obtain compound b; (3) under the condition of the nitrogen, compound b, substitution jing, in addition to the agent in the organic solvent used for the reaction, follow-up processing, to obtain compound c; (4) under the condition of the nitrogen, and the catalyst is soluble in the organic solvent c and adding alkali compound, reaction, follow-up processing, to obtain sugar alkene. Preparation method of this invention is simple, easy operation, low cost, environmental protection, with market advantage; at the same time by the invention of the preparation method of glycal yield better.
