Polyhydric alcohol fatty acid esters are mainly prepared by esterification or transesterification of fatty acids and fatty acid esters with polyhydric alcohols such as glycerol, sorbitol, sucrose, etc. The major problem is that the selectivity of the reaction is poor, and the product is usually fatty acid For mixtures of monoesters, diesters and even polyesters, it is more difficult to obtain monoesters with higher purity, which usually requires complicated separation and purification. For example, in 2017, the industrial production of fatty acid monoglycerides mainly adopted the glycerolysis method, that is, the glycerol and animal and vegetable oils were prepared by the glycerolization reaction at a high temperature of 220-260°C and the presence of an alkali catalyst. The reaction temperature is high, energy consumption is large, and side reactions are many. The resulting product is a mixture of fatty acid monoglycerides, diglycerides and triglycerides, and the content of monoesters is generally about 50%. If you want high-purity fatty acid monoglycerides, molecular distillation needs to be used for separation and purification, and molecularly distilled monoglycerides with higher purity. For sucrose with 8 free radicals, the reaction is more complicated. Theoretically, it can react with multiple fatty acids to form esterification products from monoester to octaester, generally a mixture of monoester, diester and triester. Therefore, the key to the preparation of such food emulsifiers lies in the selectivity of the reaction. In recent years, enzymes, as a kind of highly specific biocatalysts, have adopted the enzymatic method to synthesize polyol fatty acid ester food emulsifiers, which have the advantages of mild reaction conditions, high reaction selectivity, and safety. Therefore, scientists have been widely used focus on.

PSS is a kind of fucoidan diester sodium developed with alginic acid as raw material. It has the functions of anticoagulant, lowering blood lipid and blood viscosity. 1. Choosing dyes according to the nature of the fiber. Because of the different nature of various fibers, it is necessary to select suitable dyes when dyeing. For example, when cotton fiber is dyed, because its molecular structure contains many hydrophilic groups, it is easy to absorb moisture and puff, can react with reactive groups, and is more alkali-resistant, so you can choose direct, reduced, vulcanized, and ice dyes. And reactive dyes. Polyester has strong hydrophobicity and is not alkali-resistant at high temperatures. Under normal circumstances, the above dyes should not be used, but disperse dyes should be used for dyeing.
