Abstract

The invention relates to the technical field of production and application of Glyceryl tri(2-ethylhexanoate) , in particular to a polyacid-based metal organic framework and an application method of the polyacid-based metal organic framework in catalytic synthesis of Glyceryl tri(2-ethylhexanoate) . The preparation method comprises the following steps: adding glycerol and 2-ethylhexanoic acid into a reaction kettle according to a weight ratio of 1: 4.8, adding a polyacid-based metal organic framework accounting for 0.5-1% of the total mass of reactants at the same time, stirring and reacting for 30-50 minutes, and keeping the reaction temperature at 60-70 DEG C; after the reaction is completed, filtering, separating and recovering the polyacid-based metal organic framework; and adding the product left after separation into water for chromatography, washing and drying to obtain the Glyceryl tri(2-ethylhexanoate) . According to the method, the polyacid zinc metal organic framework nano material is used for replacing acid to catalyze the esterification reaction of the Glyceryl tri(2-ethylhexanoate) , the catalyst has the advantages of being simple to synthesize, recyclable, reusable, free of corrosion to a reaction container, high in catalytic efficiency and the like, and the whole esterification reaction is simple to operate and short in reaction time.

Description

technical field [0001] The invention relates to the technical field of production and application of glyceryl triethylate, in particular to a polyacid-based metal-organic framework and its application method in catalyzing the synthesis of glyceryl triisocaprylate. Background technique [0002] Glyceryl triethylhexanoate is a neutral oil with good chemical stability and thermal stability. At the same time, it has good frost resistance, spreadability and air permeability, and also has excellent solubility and dispersibility for biological active substances, organic sunscreens and pigment powders; it is currently widely used in skin care creams, lotions, and essential oils , makeup, foundation, hair care products, is an ideal cosmetic oil. The industrial synthesis of glyceryl triethylhexanoate is usually obtained by the esterification reaction of glycerin and 2-ethylhexanoic acid with acids such as concentrated sulfuric acid and organic acids as catalysts. Although the produc...
