Top quality glycine betaine cas 107-43-7
(1) Extraction method. The mother liquor of sugar beet contains 12%-15% betaine, which can be directly recovered. 300 parts of the mother liquid was heated to 50 ° C, 80 parts of calcium chloride was added, and after stirring for a certain period of time, it was filtered while hot. The filtrate was acidified with hydrochloric acid, cooled to 20-30 ° C for crystallization, separated and dried to obtain about 30 parts of betaine.
(2) Synthesis method. It is obtained by quaternizing chloroacetic acid and trimethylamine, neutralizing 195 parts of 48.6% aqueous solution of chloroacetic acid into sodium chloroacetate solution with 16% sodium hydroxide solution, and then mixing with 360 parts of 16.4% trimethylamine solution. The cells were ventilated at 50 ° C for 1 h and then ventilated at 80 ° C for 1 h. The reactants were diluted and passed through an ionic resin (Dowex-50).
-8) Adsorption, ammonia water eluted to obtain a betaine solution. The product is concentrated by vacuum and crystallized. ...
