What is Tributyl Phosphate?

With the progress of science and technology and the development of society, chemical products have invariably permeated our daily lives, in medicine, food, cosmetics, electronics, industry, and other areas, becoming an essential part of our lives. One such product is Tributyl Phosphate which has developed particularly rapidly in recent years. Do you know about Tributyl Phosphate?

The official answer:Tributyl phosphate is an organic compound that is a colourless, irritating smelling liquid. Mainly used as a solvent, it is also often used as a plasticiser for nitrocellulose, cellulose acetate, chlorinated rubber and polyvinyl chloride, extractant for rare metals, etc., heat exchange medium. Due to its low surface tension and insoluble in water, it can be used as an industrial defoamer, effectively defoaming the film of formed foam in an unstable state and defoaming it rapidly. Not for use in food/cosmetics.

What’s the application of Tributyl Phosphate?

Used as a fixative for gas chromatography, as a solvent for nitrocellulose and ethylcellulose, as a plasticizer, as an agent for the separation of rare earth metals and as an intermediate in organic synthesis
