Tetrahydromethyl-1,3-isobenzofurandione is an organic compound with the chemical formula C9H10O3. It is also known by its common name, tetrahydrophthalic anhydride (THPA). Here are some key points about tetrahydromethyl-1,3-isobenzofurandione:
Properties: Tetrahydromethyl-1,3-isobenzofurandione is a white solid with a characteristic odor. It is relatively stable under normal conditions but can slowly hydrolyze in the presence of water. It is soluble in organic solvents like acetone, ether, and chloroform.
Synthesis: Tetrahydromethyl-1,3-isobenzofurandione can be synthesized by the catalytic hydrogenation of maleic anhydride. The hydrogenation process reduces the double bonds of maleic anhydride, resulting in the formation of the tetrahydrofuran ring.
Applications: Tetrahydromethyl-1,3-isobenzofurandione is primarily used as a chemical intermediate in the production of various resins, coatings, and plastics. It is a key building block for the synthesis of polyesters, polyimides, and alkyd resins. It can also be used as a curing agent for epoxy resins and as a crosslinking agent for certain polymers.
Reactivity: Tetrahydromethyl-1,3-isobenzofurandione undergoes hydrolysis in the presence of water, converting it back to maleic anhydride. It can also undergo reaction with various nucleophiles, such as alcohols and amines, to form esters and amides, respectively.
