Description

3-Methyltetrahydrophthalic anhydride is a polycarboxylic acid that can be used as a chemical intermediate. It is typically used to synthesize polyvinyl chloride (PVC) by reacting with ethylene. This process requires the use of an organocatalyst, such as titanium tetrachloride, which converts 3-methyltetrahydrophthalic anhydride into vinyl chloride monomer. 3-Methyltetrahydrophthalic anhydride also reacts with other aromatic hydrocarbons in the presence of a catalyst to form alicyclic compounds. The activation energy for this reaction is 31 kJ/mol and the viscosity of 3-methyltetrahydrophthalic anhydride is 1.5 centipoise at 25 degrees Celsius and 1 atmosphere pressure.
