Yiziphi izinzuzo ze-anhydride yama-maleic?

I-anhydride yama-Maleic (ebizwa nangokuthi i-cis-butenedioic anhydride) iyinto ebalulekile yamakhemikhali ephilayo, ebekwe endaweni yesithathu phakathi kwama-anhydride (ngemuva kwe-phthalic anhydride kanye ne-acetic anhydride). Isetshenziswa kakhulu ukukhiqiza ama-polyester angagcwali kanye nama-resin e-alkyd, futhi ithola ukusetshenziswa ezibulala-zinambuzane, ezimbozweni, kuma-inki, ezithasiselweni zokugcoba, kumakhemikhali okwenza amaphepha, kuma-ejenti okuqeda izindwangu, kanye nama-surfactant. Izinto ezivela ku-anhydride yamaleic zifaka phakathi i-1,4-butanediol, γ-butyrolactone, tetrahydrofuran, maleic acid, fumaric acid, kanye ne-tetrahydrophthalic anhydride—konke lokhu kumakhemikhali abalulekile emvelo nacolekile.

Kungani ukhetha i-Maleic Anhydride? Iwumgogodla wama-resin e-polyester angagcwele aphezulu, futhi ivula amakhemikhali ahlukahlukene angaphansi (i-BDO, i-THF, njll.). Sithumelele umyalezo manje ukuze uhlole izixazululo ze-MA ezenzelwe ibhizinisi lakho!
