Abstract

The invention provides a new method for the preparation of high value-added chemicals by selective photocatalytic oxidation of glucose, that is, the rutile phase TiO2 loaded with metal promoters 2 As a photocatalyst, glucose can be directly converted into arabinose and erythrose through photocatalytic dehydrogenation and oxidation at room temperature. The yields of arabinose and erythrose prepared by the method are above 45mol% and 26mol% respectively. The reaction conditions are mild, no need to add acid, alkali and organic solvent, and no high temperature and high pressure conditions.

Description

technical field [0001] The invention relates to a new method for preparing arabinose and erythrose by using glucose as raw material. Specifically, the present invention relates to a reaction process for directly dehydrogenating glucose into arabinose and erythrose under photocatalytic conditions. Background technique [0002] With the increasingly serious energy crisis and the rapid consumption of non-renewable resources, the use of renewable resources to replace non-renewable resources is attracting more and more attention from all over the world. Carbohydrates, also known as sugar compounds, are the most abundant and widely distributed organic compounds in nature, and are the most important component of biomass. [0003] Glucose is the main product of cellulose hydrolysis and is the main platform small molecule for cellulose conversion. Glucose can be used to synthesize a series of products with huge market potential and high added value. Glucose is a polyhydroxy aldehy...
