Application:

1.It is one of the important organic chemical raw materials for the production of plasticizers, alkyd resins, unsaturated polyester resins, dyes and pigments, pharmaceuticals and pesticides.

2. Phthalic anhydride, referred to as phthalic anhydride, is an intermediate of the fungicide sterilization dan, the insecticide iminothion, and the herbicide herbicide herbicone.
3.Its main derivatives are dibutyl phthalate, dioctyl ester and diisobutyl ester, which are used as plasticizers such as PVC,It can also be used to produce a variety of paints, food additives, phenolphthalein in medicine, iminothion in pesticides, herbicone and sodium saccharin.
4.Standard solution for calibrating bases, separation of primary alcohols from secondary alcohols and tertiary alcohols. Depending on the melting point at which the derivatives are formed, primary amines and aromatic hydrocarbons are detected. Remove benzene in thiophene.
