Production of Maleic Anhydride,ng benzene as a raw material.(1. In 1930, Monsanto made available MA which was a by-product of their phthalic anhydride manufacture. Petrotex also used their butene-based process in the early 1960s, which was later abandoned in favor of a benzene-based process in 1967. Benzene is still the most popuflutter 发表于 2025-3-23 20:36:31
Reactions of Functional Groups,dergo reactions that are typical of an olefin, but, in addition, it enters into reactions such as nucleophilic addition. The electrophilic character of the double bond produced by conjugation plays a significant role in a number of reactions of MA including Diels-Alder, some photoreactions, and so o暗讽 发表于 2025-3-23 22:15:33
Diels-Alder Reaction,cance is the formation of a cyclohexene derivative . from a conjugated diene (butadiene) . and a dienophile (maleic anhydride, MA) . as reported by Otto Diels and Kurt Alder in 1928..* This reaction is called the Diels-Alder (DA) reaction, diene synthesis, or the cycloaddition reaction.

Homopolymerization,olecule of both an electron-acceptor double bond and an anhydride moiety confers unique properties to MA and enables the monomer to be used in both addition and condensation polymerization systems. In fact, one of the largest uses of the monomer, unsaturated polyester resins, employs both moieties fantecedence 发表于 2025-3-24 19:54:25
