Choline chloride or N-(2-Hydroxyethyl) trimethylammonium chloride is an organic compound and a quaternary ammonium salt. The counterion is chlorine. In the laboratory choline can be prepared by methylation of dimethylethanolamine with methyl chloride. In the industrial Davy process choline chloride is produced from ethylene oxide, hydrochloric acid, and trimethylamine.
The manufacturing process of choline chloride involves a chemical reaction between trimethylamine (TMA) and ethylene oxide (EO). Trimethylamine is typically derived from natural gas or coal gasification, while ethylene oxide is obtained from the petrochemical industry. This reaction is known as quaternization, wherein trimethylamine reacts with ethylene oxide to form choline chloride. The reaction requires the presence of a catalyst, such as alkali or acid catalysts. Reaction conditions, including temperature, pressure, and reactant ratios, are carefully controlled to achieve optimal yield and quality. After the reaction is complete, the resulting mixture contains choline chloride along with by-products and unreacted starting materials.
Choline chloride has several potential health benefits for humans, and it is often considered as an essential nutrient. While it is not officially recognized as a vitamin, it plays a crucial role in various physiological processes.
Choline chloride also has various industrial uses, particularly in the chemical and manufacturing sectors. Some applications include: Textile Industry, Oil Industry, Plastics and Rubber Industry, and Water Treatment.
Choline chloride is widely used as a feed additive in animal nutrition, particularly in poultry and livestock industries. Its applications include: Growth Promotion, Liver Function, Egg Production, and Meat Quality.
