Abstract

The invention discloses a method for synthesizing glycerol acetonide, and relates to the technical field of chemical synthesis. The synthesis method of glyceryl acetate acetonide provided by the present invention uses acetic acid and glycerol acetonide as raw materials to react at low temperature to generate glyceryl acetate acetonide under the synergistic action of a catalyst and a pulsed electric field (PEF), so that it can be achieved at a lower temperature. The purpose of making the catalyst achieve higher catalytic efficiency. The synthesis method provided by the invention has the characteristics of low reaction temperature, short reaction time, high efficiency, easy control of conditions, environmental friendliness, low production cost, suitable for industrial scale production and the like.

Description

technical field [0001] The invention relates to the technical field of chemical synthesis, in particular to a synthesis method of glyceryl acetate acetonide. Background technique [0002] Glyceryl acetate acetal is an organic compound with a bifunctional structure, and its chemical structure is as follows: [0003] [0004] There are ether bonds, ester bonds and different alkyl groups in the molecule of glyceryl acetate acetal. Based on the principle of similar miscibility, it can not only dissolve organic molecules, synthesize natural polymer compounds, but also be miscible with water or water-soluble compounds to varying degrees. Its solvent performance is superior to general solvents (such as ethyl acetate, acetone, xylene, etc.), and it can dissolve small molecular organic matter, macromolecular organic matter, and synthetic and natural high molecular organic matter, and can form azeotropes with water. Its performance is better than that of glycol ether and propylene...
