Ziziphi iindlela zokusebenzisa i-anhydride ye-maleic?

I-anhydride ye-Maleic (ekwabizwa ngokuba yi-cis-butenedioic anhydride) yinto ephambili kwi-organic chemical raw material, ibekwe kwindawo yesithathu phakathi kwe-anhydride (emva kwe-phthalic anhydride kunye ne-acetic anhydride). Isetyenziswa kakhulu ukuvelisa ii-polyester ezingagcwaliyo kunye nee-alkyd resins, kwaye ikwasetyenziswa nakwizibulali zinambuzane, kwiingubo, kwii-inki, kwizithambisi zezithambisi, kwiikhemikhali zokwenza iphepha, kwii-arhente zokugqiba amalaphu, nakwii-surfactants. Izinto ezivela kwi-maleic anhydride ziquka i-1,4-butanediol, γ-butyrolactone, tetrahydrofuran, maleic acid, fumaric acid, kunye ne-tetrahydrophthalic anhydride—zonke ezi zinto zibalulekileyo kwi-organic kunye neekhemikhali ezintle.

Kutheni ukhetha iMaleic Anhydride? Yisiseko seeresini zepolyester ezingagcwaliyo eziphezulu, kwaye ivula iikhemikhali ezahlukeneyo ezisezantsi (i-BDO, i-THF, njl.njl.). Sithumelele umyalezo ngoku ukuze uhlole izisombululo ze-MA ezenzelwe ishishini lakho!
