Method for preparing compound betaine

Abstract

The present invention uses betaine to enclose choline chloride and belongs to the technical field of betaine preparing method. The mainly solved problem the invention is to provide a safe and high efficient method for preparing the compound betaine. The adopted technical scheme comprises the following steps: step 1, spraying the liquid choline chloride to the flowing carrier in a fluidized bed, and drying the carrier which is sprayed with the liquid choline chloride in time through a drying device, wherein the weight part ratio of the choline chloride and the carrier is 1:1-2; and step 2, mixing the dried compound into the liquid becholine according to a weight proportion of 1:1.5, then spraying the mixed solution through high-speed centrifugation, and executing high-temperature instant drying in the temperature of 110 DEG C to 130 DEG C for obtaining the finished product. The method for preparing the compound betaine according to the invention is widely applied to the feed additive manufacturing industry.

Description

technical field

[0001] The preparation method of the compound betaine of the invention belongs to the technical field of betaine preparation methods. Background technique

[0002] The chemical name of betaine is trimethylglycine hydrochloride, which is a quaternary amine alkaloid. Molecular formula is C 5 h 11 NO 2 . It can be dissolved in water and alcohol, the aqueous solution is acidic, can withstand high temperature below 200 ℃, and has strong anti-oxidation properties. As a new feed additive for livestock and poultry, betaine has a profound impact on the growth and carcass quality of livestock and poultry.

[0003] Choline (scientific name 2-hydroxyethyl-trimethylcholine hydroxide), a kind of vitamin B. Choline can promote fat metabolism in the liver and kidney; choline is also the basis for the body to synthesize acetylcholine, thereby affecting the transmission of nerve signals. In addition, choline is also one of the methyl sources required for the synthesis o...
