Abstract

The invention provides a method for photocatalytic selective ester aminolysis of epoxy grease. The method comprises the following step: generating a target product under the conditions of imine and aphotocatalyst by taking epoxy vegetable oil as a raw material. Imine is added into a reaction system for further aminolysis of the raw material epoxidized vegetable oil under the conditions of no solvent and no acid-base addition, and a target product can be obtained under the photocatalysis condition. The reaction relates to preparation of epoxidized vegetable oil from natural vegetable oil, andthen other substances are synthesized from the epoxidized vegetable oil so that another novel way is explored for development and utilization of natural oil. The reaction can be suitable for a large amount of grease work, such as epoxidized soybean oil, epoxidized ethyl linoleate and other epoxidized vegetable oil, the product is single and the conversion efficiency is high.

Description

technical field

[0001] The invention relates to the technical field of macromolecules, in particular to a photocatalyzed method for selective ester aminolysis of epoxy grease. Background technique

[0002] Vegetable oil is a natural polymer compound composed of fatty acid and glycerol, which is widely distributed in nature. Grease is also widely used in biological materials, polymer materials, food, cosmetics, heavy industry raw materials and other fields. It has always been the main food application, and at the same time, it can also modify vegetable oil to improve material performance. But in recent years, more and more people are using these oils to produce biofuels and chemical feedstocks. This is driven in part by rapidly rising oil prices, growing concerns about the environmental impact of using fossil oil, and the need to develop domestic renewable fuels and raw materials for industry. Vegetable oils can provide high-value renewable fatty acids for chemical and heal...
