Choline hydroxide Chemical Properties,Usage,Production

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.
