What is phthalic anhydride?

    (1) Uses. Phthalic anhydride is an important chemical intermediate in the plastics industry from which are derived numerous phthalate esters that function as plasticizers in synthetic resins. Phthalic anhydride itself is used as a monomer for synthetic resins such as glyptal, the alkyd resins, and the polyester resins.

Is polymer-supported phthalic anhydride reusable for alkene epoxidation?

    Taddei et al.26employed polymer-supported phthalic anhydride for alkene epoxidation but has never mentioned about the reusability of the polymer catalyst.

What is the odor threshold for phthalic anhydride?

    Phthalic anhydride has an odor threshold of 0.053 parts per million (ppm). (7) The chemical formula for phthalic anhydride is C H O, and it has a molecular weight of 148.12 g/mol.The chemical formula for phthalic anhydride is C8H4O3, and it has a molecular weight of 148.12 g/ mol. (3,6) -4

Does anhydride convert to methyl ester in hydrolyzed-od-Ma-co?

    Since carboxylic acid is inert to methanolysis without acid catalyst, only the anhydride is converted to methyl ester. Thus, we presumed that the amount of Od-MA-CO 2Me methyl ester rep- resented the remaining anhydride in hydrolyzed-Od-MA. In the 1H NMR spectrum of Od-MA-CO
