Indlela ye-Maleic Anhydride Benzene isebenza njani?

I-Maleic Anhydride Indlela ye-benzene
I-Maleic Anhydride C4 indlela yeengcenye. Indlela le isebenzisa iingcenye ezisebenzako (ezifana ne-butene, i-butadiene) eengcenyeni ze-C4 njengezinto ezisetjenziswako, ezisabelana nomoya (nofana i-oksijini) ekuphenduleni kwe-gas-phase oxidation ngaphasi kwesenzo se-V2O5-P2O5 catalyst ukukhiqiza i-maleic anhydride. Ngebanga leendleko eziphezulu zezinto ezisetjenziswako kanye nokuvuna okuphasi, indlela le sele iqediwe.
I-Maleic Anhydride Phthalic anhydride by-product methodNgesikhathi sokukhiqizwa kwe-phthalic anhydride evela ku-o-xylene, inani elithileko le-maleic anhydride lingatholwa njenge-by-product, elingaba yi-5% yomkhiqizo we-phthalic anhydride.

Kubayini ukhetha i-Maleic Anhydride? Ngumgogodla we-polyester resin ephezulu, begodu ivula amakhemikhali ahlukahlukeneko (i-BDO, i-THF, njll.). Sithumelele umlayezo nje ukuhlola iinsombululo ze-MA ezilungiselelwe ibhizinisi lakho!
