Njirimara kemịkalụ:

Maleic Anhydride (MAN) bụ ngwakọta organic nwere usoro kemịkalụ C4H203. Ọ bụ acid anhydride nke maleic acid na n'ọnọdụ ya dị ọcha ọ bụ ihe siri ike na-enweghị agba ma ọ bụ na-acha ọcha nke nwere isi ísì. Maleic anhydride bụ n'ezie molekul dị ịrịba ama n'ihi na ọ nwere ụdị ọrụ kemịkal abụọ na-eme ka ọ bụrụ ihe bara uru pụrụ iche na njikọ kemịkal na ngwa.

Maleic Anhydride bụ kemịkalụ kemịkalụ multifunctional yana ngwa n'ọtụtụ ngalaba nke ụlọ ọrụ kemịkalụ. Isi njedebe ya bụ dị ka nri nri na mmepụta nke polyester resins (UPR).
A na-eji resins ndị a ma na-agbanye ike na iko na ngwa ngwa na-enweghị ike. Ihe njedebe UPR gụnyere ọtụtụ ngwa na-ewu, mmiri na ụgbọ ala.
Na mgbakwunye, Maleic Anhydride nwekwara ike iji dị ka akụrụngwa na mmepụta nke 1,4-butanediol (BDO), gamma-butyrolactone na tetrahydrofuran (THF). Ọ dị mkpa ime ka ọ pụta ìhè na BDO bụ otu n'ime kemịkalụ na-eto ngwa ngwa n'ụwa n'afọ gara aga.
