Tetrahydrophthalic Anhydride: Essential for Industrial Processes
Tetrahydrophthalic anhydride (THPA), an organic compound with the CAS Number 85-43-8, plays a crucial role in diverse manufacturing procedures. Boasting a molecular formula of C8H10O3 and a molecular weight of 154.16 g/mol, THPA’s key distinguishing characteristic is its cyclic acid anhydride structure.
Salient Features
- CAS Number: 85-43-8
- Molecular Formula: C8H10O3
- Molecular Weight: 154.16 g/mol
- Synonyms: 1,3-isobenzofurandion, 3a,4,7,7a-tetrahydro-,cis-, 3-Isobenzofurandione, 3a,4,7,7a-tetrahydro-,cis-1, 4,7,7a-tetrahydro-3-isobenzofurandioncis-3a, cis-3a,4,7,7a-Tetrahydro-1,3-isobenzofurandione, CIS-THPA, CIS-DELTA4-TETRAHYDROPHTHALIC ANHYDRIDE, CIS-4
Applications
THPA’s wide range of applications primarily constitutes the production of polyester resins, alkyd resins, coatings, and special elastomers. It also finds significant use in manufacturing plasticizers, corrosion inhibitors, curing agents, and transformer oil.
Manufacturing Process
The industrial manufacturing of THPA involves two principal reactions – the Diels-Alder reaction of maleic anhydride and 1,3-butadiene, followed by the dehydration of the resulting adduct.
Safety Measures
Considered an irritant, THPA should not come into contact with skin or eyes, nor should it be inhaled or released into the environment. Use it in a well-ventilated area and wear appropriate personal protective equipment including gloves and safety glasses when handling this chemical.
