  • Can phthalic anhydride be used as a heterocyclic substrate?
  • This review has been centralized on applications of phthalic anhydride (PA) as a valuable and significant heterocyclic substrate in two- and multicomponent organic reactions. The article has been subdivided into the following parts: (i) PA introduction by focusing on its characterization, synthesizing procedure, and multiple-aspect applications.
  • Which countries use phthalic anhydride?
  • Asia is the largest consumer of phthalic anhydride for the production of plasticizer. Mainland China is the world’s largest consumer of phthalic anhydride for phthalate plasticizers. The next-largest markets for phthalic anhydride outside of Asia are Western Europe and the Indian Subcontinent.
  • What is the largest market for phthalic anhydride?
  • The largest market for phthalic anhydride is the manufacture of phthalate plasticizers, which consumed nearly half of all phthalic anhydride consumed. Asia is the largest consumer of phthalic anhydride for the production of plasticizer. Mainland China is the world’s largest consumer of phthalic anhydride for phthalate plasticizers.
  • What is phthalic anhydride?
  • Phthalic anhydride was the first anhydride of a dicarboxylic acid to be used commercially. It is an important industrial chemical used for the large-scale production of plasticizers for plastics. A. Laurent first discovered phthalic anhydride in 1836, and since 1872, it has been produced by BASF using the naphthalene oxidation process.
  • When was phthalic anhydride reacted with styrene?
  • In 1940, Ellis reported the copolymerization of maleic polyester resins with monomeric styrene. In 1947, Muskat reported that phthalic anhydride and maleic anhydride could be reacted with glycol to form a noncrystallizable unsaturated polyester, which was more compatible with styrene.
  • Where will phthalic anhydride consumption grow in 2022?
  • Above-average growth is expected in Asia (particularly in mainland China), the Indian Subcontinent, and Southeast Asia, even though consumption is declining in Japan and South Korea. Consumption of phthalic anhydride for unsaturated polyester resin production is expected to increase during 2022–27, but growth will vary by region.
