The active ingredient of betaine is trimethyl amino acid, which is an important osmotic pressure regulator and methyl donor. At present, common betaine products on the market mainly include betaine anhydrous, betaine monohydrate and betaine hydrochloride. Today we are going to talk about different betaine products on the market.

1, Betaine Anhydrous, the product solution contains betaine, by-product sodium chloride, unreacted substances and a small amount of other impurities, after removing impurities by the refining device, by drying betaine products. The purification process has some disadvantages such as complicated process, expensive instrument, high energy consumption and difficult to increase the yield, so the betaine anhydrous product prepared has a high price. The purity of product was over 98%. Because pure betaine has strong hygroscopicity and poor dispersion, about 2% anti-caking agent is often added on the market and 96% anhydrous betaine products are prepared. The pH of anhydrous betaine (10% aqueous solution) is 5-7, which is neutral. Low content of moisture, burning residue and chloride ions.

2, Betaine Monohydrate, the reaction principle is the same as betaine anhydrous, only in the process of purification to control the process, the preparation of betaine products containing 1 crystal water, molecular formula is C5H11NO2· H2O, monohydrate betaine content ≥98%, (C5H11NO2)betaine content ≥85%.The pH of monohydrate betaine (10% aqueous solution) is 5-7, which is neutral. Low content of burning residue and chloride ion.

3, Betaine Hydrochloride, betaine hydrochloride and anhydrous betaine and monohydrate betaine production process difference lies in: The second step is generated in the reaction liquid, the separation and purification of betaine complex process, high cost, in order to solve this problem, according to certain mole ratio in the mixture and hydrochloric acid, betaine combined with hydrochloric acid in the form of a covalent bond for betaine hydrochloride, the reaction with by-product sodium chloride, again not fully material and other impurity separation is much easier, relatively low energy consumption, Costs fall accordingly. The purity of betaine hydrochloride (C5H11NO2·HCl) was over 98%.Because pure betaine hydrochloride also has strong hygroscopicity and poor dispersion, part of the anti-caking agent is often added on the market.
