Zithini iipropati zomzimba nezekhemikhali ze-manhydride ye-maleic?

Iipropati zomzimba nezekhemikhali zeMaleic Anhydride: Kwiqondo lobushushu begumbi, ibonakala njengeegranules ezimhlophe, iinaliti, iiflakes, iintonga, amaqhuma okanye iibhloko, kunye nokucaphuka okukhulu. Uxinano oluhambelanayo: 1.48; Iqondo lokunyibilika: 52.8°C; Iqondo lokubila: 202.2°C. IMaleic Anhydrid inokuba shushu kakhulu kumaqondo obushushu aphantsi (60-80°C). Iyanyibilika kwi-ethanol, i-ether kunye ne-acetone; isabela namanzi ukwenza i-maleic acid. Inokutsha, kwaye umphunga wayo kunye nothuli lungadala imixube eqhumayo xa ixutywe nomoya.

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!
