Phthalic Anhydride (PA)
CAS No:
CAS:85-44-9
Molecular formula: C8H4O3
Molecular weight: 148.12
EINECS:201-607-5
Purpose:
Phthalic anhydride, abbreviated as phthalic anhydride, is an intermediate of fungicides such as fungicides such as chlorpyrifos, insecticides such as imidacloprid, and herbicides such as glyphosate.
Used as an analytical reagent and also for organic synthesis
Phthalic anhydride is one of the most important organic chemical raw materials, and its main derivatives include dibutyl phthalate, dioctyl phthalate, and diisobutyl phthalate, which are used as plasticizers for PVC and other materials; It can also be used for the production of unsaturated polyester resins, alkyd resins, dyes and pigments, various paints, food additives, laxatives such as phenolphthalein in medicine, imidacloprid in pesticides, glyphosate, and sodium saccharin.
Calibrate the standard solution of alkali and separate primary alcohols from secondary and tertiary alcohols. According to the different melting points of the formed derivatives, distinguish between primary amines and aromatic hydrocarbons. Remove thiophene from benzene.
