D-Glucose diethyl mercaptal

D-葡萄糖缩二乙硫醇,

D-Glucose diethyl mercaptal is a homogeneous catalyst that can be used to acetylate galactitol to produce D-arabinose. It acts as an efficient and selective catalyst for the reaction of nitrous acid with hydrochloric acid, which produces acetyl chloride. Acetyl chloride is a reactive compound that can be used in the synthesis of many other compounds. D-Glucose diethyl mercaptal has been used in chromatographic methods to separate d-arabinose from L-arabinose. The ring-opening polymerization of D-glucopyranose by mercaptals leads to the formation of polyols, which are useful materials for the production of plastics and rubber products. Chloride ions are required for this reaction, while hydrogen chloride is produced as a byproduct.

D-Glucose diethyl dithioacetal (DTD) is a thioacetal derivative of glucose, also known as 1,2-anhydro-3,4-di-O-ethyl-D-glucopyranose-5-thioacetate.
