Pehea ke ʻano o ke kaʻina hana ʻo Maleic Anhydride (MA) C4 Olefin?

ʻAnhydride Maleic (MA) C4 Kaʻina Hana Olefin
Hoʻohana kēia kaʻina hana i nā ʻāpana kūpono (n-butene, butadiene) i loko o nā ʻāpana C4 i hui ʻia ma ke ʻano he mea maka, kahi e hana ai me ka ea (a i ʻole oxygen) ma o ka oxidation gas-phase ma luna o kahi mea hoʻouluulu V₂O₅-P₂O₅ e hana i ka maleic anhydride ma. I ka hopena, hoʻoheheʻe mua ʻia ka n-butene i ka butadiene, a laila oxidizes i ka maleic anhydride ma. ʻO nā huahana ʻaoʻao e komo pū me CO, CO₂, wai, nā liʻiliʻi o ka acetaldehyde, acetic acid, acrolein, a me furan.

No ke aha e koho ai i ka Maleic Anhydride? ʻO ia ke kumu o nā resins polyester unsaturated kiʻekiʻe, a wehe pū ia i nā kemika like ʻole ma hope (BDO, THF, a pēlā aku). E leka mai iā mākou i kēia manawa e ʻimi i nā hoʻonā MA i hana kūikawā ʻia no kāu ʻoihana!
