Terephthalic acid
CAS No.100-21-0
Alias:Terephthalic acid 98%;Terephthalic a;Acide terephtalique;acideterephtalique;acideterephtalique(french);
Molecular formula：C8H6O4
Molecular weight：166.13
Structural formula：
1. Performance and use:
White needle-like crystal or powder. Soluble in alkali solution, slightly soluble in hot ethanol, insoluble in water, ether, glacial acetic acid and chloroform.
Important raw material for the manufacture of polyester resin, film, fibre, insulating paint and engineering plastics etc.
Most of the product is used in the production of polyethylene terephthalate (polyester), which is an important raw material for polyester fibre, film, plastic products, insulating varnish and plasticizers, and is also used in the production of pharmaceuticals, dyes and other products.
Used as a reagent for chromatographic analysis
Used in the manufacture of synthetic resins, acid fibres and plasticisers, etc.
Organic synthesis, determination of residual alkalinity of wool, gas chromatography sweeping agent. Add into polyethylene glycol 200, can separate and analyse fatty acid.
