Iipropati ze-Maleic anhydride

Iprofayili ka I-Maleic Anhydride
Iipropati ze-Maleic anhydride
I-anhydride ye-Maleic (ekwaziwa ngokuba yi-cis-butenedioic anhydride) yikristale emhlophe efana nenaliti ye-orthorhombic. Ifomula yayo yemolekyuli yi-C4H2O3.
, enobunzima beemolekyuli ezingama-98.06. Inendawo yokunyibilika engama-52.8°C, indawo yokubila engama-202°C, indawo yokutsha ye-103°C, kunye noxinano oluhambelanayo lwe-1.314. I-Maleic anhydride kulula ukuyinyibilikisa, kwaye iyanyibilika emanzini, kwiialcohols nakwii-esters, ngelixa inyibilika kancinci kwi-carbon tetrachloride kunye ne-petrol ekrwada. Zombini uthuli kunye nomphunga we-maleic anhydride ziyatsha kwaye ziyaqhuma; ziyacaphukisa abantu kwaye zinokubangela ukutsha eluswini.

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!
