Abstract

The invention discloses a preparation method of a phenylsulfonic acid-modified SBA-15 composite material, using SBA-15, a phenylsilane coupling agent and an anhydrous organic solvent as raw materials to prepare SBA-15-Ph; The obtained SBA‑15‑Ph is sulfonated to obtain a phenylsulfonic acid group modified SBA‑15 composite material; the present invention also discloses the application of the phenylsulfonic acid group modified SBA‑15 composite material in the synthesis of structural phospholipids, Using phospholipids and fatty acid methyl esters or fatty acid ethyl esters as raw materials, under the catalysis of phenylsulfonic acid group-modified SBA-15 composite materials, a new type of structural phospholipids is obtained. The modified phospholipids prepared by the present invention broaden the application range of phospholipids, and at the same time, the residual organic matter in the product is less; it can also solve the disadvantages of expensive enzyme sources, difficult recycling, and not wide reaction conditions in the process of enzymatic production of structural phospholipids, and finally improve the structure Preparation method of phospholipids.

Description

technical field [0001] The invention relates to a preparation method and application of a catalyst, in particular to a preparation method of a phenylsulfonic acid group-modified SBA-15 composite material and its application in synthesizing structural phospholipids. Background technique [0002] Phospholipids are essential components of cellular infrastructure and play an important role in maintaining cell permeability and intracellular oxygen delivery. In addition, phospholipid is also a natural amphoteric surfactant, which has various properties such as emulsification, dispersion, and wetting, and can reduce skin surface tension and enhance bone function. Therefore, phospholipids have a wide range of applications in the fields of cosmetics, medicine, food, leather and industrial additives. Natural phospholipids exist in a wide range. Phospholipids exist in soybeans, egg yolks, and animal internal organs. Among them, soybean phospholipids are the most widely used because of...
