Shandong E.fine is a professional manufacturer of Betaine , here let us learn about the production species of betaine.

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

1. Betaine anhydrous :

The refining and purification process is complicated,because of the shortcoming of using the expensive equipment  , high energy consumption ,and not easy to improve the yield ,the cost of betaine anhydrous is high. The content of betaine anhydrous ((C₅H₁₁NO₂) is 98% .

Because 98% betaine has strong hygroscopicity and poor liquidity , so we usually recommend the product 96% betaine anhydrous with  2% anti-caking agent.  The liquidity of 96% betaine is better and more easy to storage .

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

Monohydrate betaine, the reaction principle is the same as anhydrous betaine, we only need to control the purification process to make  1 crystal water, the molecular formula is C5H11NO2· H2O, monohydrate betaine content ≥98%, (C5H11NO2) 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 hcl

The differences between betaine hydrochloride and anhydrous betaine and monohydrate betaine in the production process are as follows:  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,  Corresponding cost reduction  .

The purity of betaine hydrochloride (C5H11NO2·HCl) was over 98%. Because pure betaine hydrochloride also has a strong hygroscopicity, poor dispersion, the market often add a part of anti-caking agent.

The pH of betaine hydrochloride (1+4 aqueous solution) is 0.8-1.2, showing strong acidity. The content of water and burning residue is very low. The chloride ion content is about 22%.
