Abstract

The invention relates to a preparation method of low-burning residue betaine hydrochloride co-producing sodium fluorosilicate. The industrial by-product fluorosilicic acid is used as a raw material to react with sodium chloride in an amination solution, and the generated hydrogen chloride reacts with sugar beet. Betaine hydrochloride is prepared by combining with alkali, and at the same time, the sodium fluorosilicate product which has a wide range of industrial uses is co-produced, and the comprehensive utilization of sodium chloride is realized. It is of great significance for large-scale production, improving economic benefits, and reducing environmental pressure, and is suitable for industrial production.

Description

technical field [0001] The invention relates to a preparation method of fine chemicals, in particular to a preparation method of low-burning residue betaine hydrochloride co-producing sodium fluorosilicate. Background technique [0002] Betaine hydrochloride, also known as trimethylamine glycine lactone hydrochloride, Cas number: 590-46-5, English name: 1-Carboxy-N,N,N-trimethylmethanaminium chloride, white to slightly yellow crystalline powder , The taste is sour, with moisture absorption, easily soluble in water, ethanol, insoluble in ether, chloroform, and reacts with alkali. Betaine hydrochloride is a high-efficiency, high-quality and economical food-inducing and growth-promoting nutritional additive, which can relieve stress, regulate osmotic pressure, increase appetite, stabilize vitamins, and reduce fat. It can be used as a substitute for methionine and choline chloride. It is widely used in livestock, poultry, aquaculture and various pet animal feeds. [0003] Sodi...
