Izakhiwo ze-anhydride ye-Maleic
I-anhydride yama-Maleic (eyaziwa nangokuthi i-cis-butenedioic anhydride) iyikristalu emhlophe efana nenaliti ye-orthorhombic. Ifomula yayo yama-molecule yi-C4H2O3.
, enesisindo sama-molecule angu-98.06. Inezinga lokuncibilika elingu-52.8°C, izinga lokubila elingu-202°C, izinga lokusheshisa elingu-103°C, kanye nobuningi obuhlobene obungu-1.314. I-Maleic anhydride kulula ukuyikhulisa, futhi incibilika emanzini, kuma-alcohol kanye nama-ester, kuyilapho incibilika kancane ku-carbon tetrachloride kanye nophethiloli ongahluziwe. Kokubili uthuli kanye nomhwamuko we-maleic anhydride kuyavutha futhi kuyaqhuma; kuyacasula kubantu futhi kungabangela ukusha esikhumbeni.

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!
