Me pēhea te whakahaere i te Tikanga Maleic Anhydrogenation?

Anhydride Maleic tikanga whakahauwai
Tikanga Butadiene anhydride maleic. Ka pāngia te 1,3-butadiene e te acetoxylation me te waikawa acetic me te hāora hei whakaputa i te 1,4-diacetoxy-2-butene, kātahi ka hurihia hei 1,4-butanediol mā te hauwai me te hydrolysis.
Te tikanga maleic anhydride 1,4-dichlorobutene. Ko te 1,4-dichlorobutene he takawaenga i roto i te hanga chloroprene mai i te butadiene. Mā te whakamahi hei rauemi mata, ka whiwhihia te 1,4-butanediol mā te hydrolysis me te hydrogenation.
