Sehlahisoa sebopeho sa molek'hule:

Lintho tsa Lik'hemik'hale:

Maleic Anhydride (MAN) ke motsoako oa manyolo o nang le foromo ea lik'hemik'hale C4H203. Ke asiti ea anhydride ea asiti ea maleic 'me boemong ba eona bo hloekileng ke ntho e se nang 'mala kapa e tšoeu e tiileng e nang le monko oa acrid. Maleic anhydride ehlile ke molek'hule e makatsang kaha e na le mefuta e 'meli ea ts'ebetso ea lik'hemik'hale e e etsang hore e be ea bohlokoa ka tsela e ikhethang inchemical synthesis le ts'ebeliso.

Maleic Anhydride ke lik'hemik'hale tse sebetsang ka bongata tse sebelisoang likarolong tse 'maloa tsa indasteri ea lik'hemik'hale. Tšebeliso ea eona e kholo ea ho qetela ke ea ho fepa lihlahisoa tsa lihlahisoa tsa polyester resins (UPR).
Li-resin tsena li sebelisoa ka bobeli ka likhalase tse matlafalitsoeng le lits'ebetsong tse sa matlafatsoang. Tšebeliso ea ho qetela ea UPR e kenyelletsa mefuta e mengata ea likopo ho indasteri ea kaho, ea metsing le ea likoloi.
Ho phaella moo, Maleic Anhydride e ka boela ea sebelisoa e le lisebelisoa tse tala ha ho etsoa 1,4-butanediol (BDO), gamma-butyrolactone le tetrahydrofuran (THF). Ho bohlokoa ho totobatsa hore BDO ke e 'ngoe ea lik'hemik'hale tse holang ka potlako lefatšeng lilemong tse fetileng.

Kopo:

Ho Diels-Alder syntheses (e le dienophile), ho etsoa ha alkyd-mofuta oa li-resin, li-intermediate tsa dae, meriana, lik'hemik'hale tsa temo (maleic hydrazide, malathion), ka liketso tsa copolymerization.

Maleic Anhydride ke motsoako oa heterocyclic o sebelisoang ha ho etsoa li-resin tsa polyester tse sa tsitsang. Maleic Anhydride e na le mefuta e mengata ea lisebelisoa tse ling; e sebelisoa ho li-tensides tsa maiketsetso, meriana e bolaeang likokoanyana, meriana e bolaeang limela le fungicides.
