Abstract

The invention relates to a preparation method of an adsorption material used for diethyl sebacate. The preparation method comprises the following steps: adding, by weight, vinylidene fluoride, diallylterephthalate, propylallyl disulfide, 6-(1'-tert-butyldimethylsilyloxyethyl)-2-(2''-tetrahydrofuryl)-penem-3-carboxylate, bis(pentamethylcyclopentene)titanium dichloride, dodecylbenzene sulphonic acid and water into reaction vessel; successively carrying out uniform mixing, heating and a reaction; and after completion of the reaction, subjecting a product of the reaction to filtration, washing and drying so as to obtain the adsorption material for diethyl sebacate.

Description

technical field [0001] The invention relates to a preparation method of an adsorption material, in particular to a preparation method of an adsorption material for diethyl sebacate. Background technique [0002] Diethyl sebacate, English name: diethyl sebacate, colorless to light yellow liquid, with the aroma of wine, fruit and melon, can be used in organic synthesis; GB 2760-96 stipulates that it is temporarily allowed to use food spices. It is mainly used in the preparation of berry flavors and as a solvent for fruit flavors; GB 2760-96 stipulates that it is a food flavor that is allowed to be used. It is mainly used as a solvent for preparing grape, pear and other flavors and fruit flavors; as a plastic cold-resistant plasticizer, solvent and organic synthesis intermediate. It can also be used in the pharmaceutical industry; as a solvent for polymer compound synthesis. [0003] CN105130814A discloses a method for preparing diethyl sebacate by catalyzing methanesulfonic ...
