He aha nā kaʻina hana synthesis ma waho no ka maleic anhydride?

Nā Kaʻina Hana Hana ma waho
ʻOihana o kēia manawa ʻAnhydride Maleic ʻO nā ala hana e pili ana i ka benzene, ka n-butane, ka C4 olefin, a me ka phthalic anhydride byproduct.
Ua lōʻihi ka manawa i lilo ai ʻo Benzene i mea maka kuʻuna no ka maleic anhydride, akā ua hoʻokele nā ​​​​kumu waiwai benzene i ka hoʻomohala ʻana o nā ala C4 olefin a me n-butane. Ua hoʻonui koke nā ʻāina waiwai i ke kinoea kūlohelohe a me ke kinoea e pili ana i ka ʻaila (nāna e hāʻawi i ka nui o ka n-butane) i nā kaʻina hana n-butane—i kēia manawa he ~80% o ka mana hana honua.

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!
