Uses

Choline Dihydrogen Citrate can be used to synthesize compounds that can improve the photosynthetic efficiency of plants. It can also be used for synthesizing cleaning compounds that can be used for dishwashing, oven cleaning, microwave oven cleaning, floor cleaning, or surface cleaning. Furthermore, Choline Dihydrogen Citrate can potentially be used in the treatment of multiple sclerosis. Additionally, Choline Dihydrogen Citrate can also be use as a component of a nutritional supplement that can be used for improving cerebral activity.

Manufacturing Process

30 lb of trimethylamine were added to 70.4 lb of methyl alcohol to which 9.2 lb of water had previously been added. To the resulting solution in a closed vessel 23 lb of ethylene oxide gas were introduced and the resulting mixture then maintained at a temperature of 16 C to 30 C and agitated for 6 hours. During the reaction the pressure in the reaction vessel varied from about 17.5 psi at the start of the reaction to 0 psi at the end of the reaction. The resulting solution was then added with agitation to a refluxing solution of 40 liters of isopropyl alcohol containing 95 lb of citric acid dissolved therein. This mixture was then cooled to 0°C and held at that temperature overnight. The white crystalline choline dihydrogen citrate which formed was separated from the solvent mixture by filtration and dried in vacuo. 117 lb of anhydrous, crystalline choline dihydrogen citrate having a purity of 99.6% were obtained. This was a yield of 78% based on the amount of trimethylamine employed.
