He aha te āhua o te Tukanga Maleic Anhydride (MA) C4 Olefin?

Maleic Anhydride (MA) C4 Tukanga Olefin
Ka whakamahia e tēnei tukanga ngā wāhanga whai hua (n-butene, butadiene) i roto i ngā wāhanga C4 whakaranu hei rauemi mata, ka tauhohe ki te hau (te hāora rānei) mā te whakakōkī hau-āhua i runga i te whakakōkī V₂O₅-P₂O₅ hei whakaputa i te maleic anhydride ma. I roto i te tauhohenga, ka mimiti te n-butene ki te butadiene, kātahi ka whakakōkī ki te maleic anhydride ma. Ko ngā hua taha ko te CO, CO₂, te wai, he iti noa te acetaldehyde, te waikawa acetic, te acrolein, me te furan.

He aha koe i whiriwhiri ai i te Maleic Anhydride? Koinei te pou tuarā o ngā kapia polyester kounga teitei, ā, ka wetewetehia hoki ngā matū rerekē o muri mai (BDO, THF, me ētahi atu). Tukua mai he karere inaianei hei tūhura i ngā otinga MA kua whakaritea mō tō pakihi!
