Phthalic Anhydride 99.7% AR Grade Reagent
Cas Number: 85-44-9
Formula: C8H4O3
Molar Mass:148.12
EC Number:201-607-5
Physicochemical properties:
White shiny needle crystals. Sublimate. It is soluble in hot water, phthalic acid, soluble in ethanol, slightly soluble in cold water, carbon disulfide and ether. The relative density is 1.53. The melting point is 130.8 ° C. The boiling point is 295 ° C. The flash point is 152 ° C. Irritating.
Usage:
A standard solution of the base is calibrated. The primary alcohol is separated from the secondary alcohol and the tertiary alcohol. Primary amines and aromatic hydrocarbons are checked depending on the melting point. The thiophene in benzene is removed.
Packing:
500g/25kg
