Pehea e hana ʻia ai ke ʻano hana Maleic Anhydrogenation?

ʻAnhydride Maleic ke ʻano hydrogenation
ʻO ke ʻano hana Butadiene anhydride Maleic. Hoʻopili ʻia ka 1,3-butadiene i ka acetoxylation me ka waikawa acetic a me ka oxygen e hana i ka 1,4-diacetoxy-2-butene, a laila hoʻololi ʻia i 1,4-butanediol ma o ka hydrogenation a me ka hydrolysis.
ʻO ke ʻano hana maleic anhydride 1,4-dichlorobutene. ʻO 1,4-dichlorobutene kahi waena i ka hana ʻana o ka chloroprene mai butadiene. Me ka hoʻohana ʻana iā ia ma ke ʻano he mea maka, loaʻa ka 1,4-butanediol ma o ka hydrolysis a me ka hydrogenation.

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!
