| | Choline hydroxide Usage And Synthesis |
| Description | Choline hydroxide or choline base is also known as 2-hydroxyl ethyl trimethyl ammonium hydroxide. It is a strong yet organic base.
Choline hydroxide is primarily used to produce other choline salts, which could be used in nutraceuticals, baby food, etc. Choline hydroxide can be used as phase transfer catalysts which carry the hydroxide ion into organic systems. It is used as an ingredient in cleaning and developer formulations in the electronics and printed circuit board industry and in paint stripping formulations. It can also be used as corrosion inhibitor, for the H2S removal from gas streams. Furthermore, it is used as the cleaning and degreasing agent in the metal industry.

| | Chemical Properties | clear light yellow viscous solution | | Uses | Choline hydroxide is used as a precursor molecule for the neurotransmitter acetylcholine, it is involved in several functions including muscle and memory muscle control. It was used as a basic catalyst for aldol condensation reactions. | | Uses | Choline hydroxide solution has been used in the synthesis of choline hexafluoroacetylacetonate that can be used as an extractant along with bis-(trifluoromethylsulfonyl)imide ionic liquid for the homogeneous liquid-liquid extraction of neodymium(III). | | Definition | An amino alcohol,CH2OHCH2N(CH3)3OH. It occurswidely in living organisms as aconstituent of certain types ofphospholipids– the lecithins andsphingomyelins– and in the neurotransmitteracetylcholine. It issometimes classified as a memberof the vitamin B complex. | | Flammability and Explosibility | Non flammable | | Synthesis | A method for preparing high purity choline from choline chloride, said method being carried out in the following steps: 1) pretreating a strongly acidic cation exchange resin, said pretreatment process being: acid treatment, ultrapure water treatment to neutrality, alkali treatment, ultrapure water treatment to neutrality, and then repeating the steps of acid treatment/ultrapure water treatment more than two times, and ultimately rinsing with a large amount of ultrapure water, to obtain strongly acidic cation exchange resin columns after pretreatment; 2) passing an aqueous choline chloride solution through at least one set of strongly acidic cation exchange resin columns after pretreatment to remove cation impurities therein; 3) passing the aqueous choline chloride solution through the strongly acidic cation exchange columns through a bipolar membrane electrodialysis treatment to obtain an aqueous choline solution and a hydrochloric acid solution; 4) The strongly basic anion exchange resin column is pretreated, and the pretreatment process is in the following order: alkali treatment, ultrapure water treatment to neutrality, acid treatment, ultrapure water treatment to neutrality, and then repeating the alkali treatment/ultrapure water treatment step more than two times, and ultimately rinsing with a large amount of ultrapure water, to obtain the pretreated strongly basic anion exchange resin column; 5) passing the aqueous solution of choline obtained in step 3) through the At least one set of pretreated strongly basic anion exchange resin columns to remove the anion impurities therein, and then distill and concentrate the obtained aqueous choline solution under reduced pressure to a desired concentration to obtain an ultrapure aqueous choline solution. |
