| Questions And Answer | Back Directory | [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.
