Chemical Properties:
  1. Choline, namely hydroxyethyl trimethylamine, is a kind of quaternary ammonium base. It is a colorless crystal or a colorless, bitter, water-soluble white slurry. It has strong hygroscopicity and can quickly absorb water when exposed to the air. Choline easily reacts with acid to form a more stable crystalline salt (such as Chemicalbook Choline Chloride), which is also unstable under strong alkaline conditions, but is quite stable to heat and storage. As a strong organic base, it can be completely ionized in water and has a low metal content. Its chemical properties make choline widely used in the chemical and semiconductor fields.
  2. Strong alkaline viscous liquid or crystal, bitter taste. The relative density of 50% aqueous solution is 1.073, and the refractive index is 1.4304. Soluble in water and ethanol, insoluble in Chemicalbook ether, etc. It is easy to absorb carbon dioxide in the air, has strong water absorption, and decomposes when exposed to heat. ADI does not make restrictions (FAO/WHO, 1994).
  1. As a food fortifier. It can be used in foods for infants and young children, with a dosage of 380-790mg/kg and a dosage of 50-100mg/kg in the liquid. Use Intermediate in organic synthesis; used in biochemical research. Uses: It can be used as a reagent for biochemical research; it can also be used as a cation for environmentally friendly degradable ionic liquids; it is also a cleaning agent for semiconductor manufacturers.
  2. Use It is used as the production method of Chemicalbook biochemical reagent. After formaldehyde is methylated with ammonium chloride to obtain trimethylamine, it is then added with ethylene oxide to obtain choline. Production method Add the trimethylamine ethanol solution into the reaction pot, pass ethylene oxide at about 30°C, stir and react for 4 hours to obtain the product.
