Product Description

Top quality Phthalic Anhydride 99.8% Used For Resin  CAS:85-44-9

 

CHEMICAL NAME: Phthalic Anhydride 99.8% 

Formula: C8H4O3

CAS No.: 85-44-9

F.W.: 148.11

UN NO.: 2214
Properties : 

It is a precursor to a variety of reagents useful in organic synthesis. Important derivatives include phthalimide and its many derivatives. Chiral alcohols form half-esters (see above), and these derivatives are often resolvable because they form diastereomeric salts with chiral amines such as brucine. A related ring-opening reaction involves peroxides to give the useful peroxy acid:

C6H4(CO)2O + H2O2 → C6H4(CO3H)CO2H

Application :

1. Mainly used in the production of plastic plasticizer, alkyd resin, dye, unsaturated resin and some medicine and pesticide.

2. Applications in industry and organic synthesis.

3. Hydrolysis of anhydrides is not typically a reversible process. However, phthalic acid is easily dehydrated to form phthalic anhydride due to the creation of a thermodynamically favorable 5-membered ring.

4. Widely used in industry for the production of certain dyes. A well-known application of this reactivity is the preparation of the anthroquinone dye quinizarin by reaction with para-chlorophenol followed by hydrolysis of the chloride.
