Whakakoki Whakakotahitanga me te Waa Waiwai whakakorikori
Ina whakamahia te ethylene me te propylene mai i te pakaru o te hauwai waro hinu hei rauemi polymerization, ka hiahiatia te hauwaitanga whiriwhiri hei tango i nga mea poke penei i te alkyne, diene, carbon monoxide, carbon dioxide me te oxygen, me te kore e ngaro te korefin.Ko te whakakorikori e whakamahia ana ko te palladium, te konukawata, te nickel ranei, te cobalt, te molybdenum, me etahi atu, i runga i te alumina.He whakakōkī hauwais he rereke nga ahuatanga ka taea te whiwhi ma te whakahaere i te nui o te matū kaha, te tikanga hanga tautoko me te whakakorikori.Ko etahi atu penei i te pakaru penehīni para, te nitrobenzene hydrogenation reduction ki te aniline, hydrogenation catalyst.
He whakakōkī mō te hauwai hōhonu ki ngā pūhui kukū.Pērā i te hauwai benzene ki te cyclohexane me te nickel alumina catalyst, te phenol hydrogenation ki te cyclohexanol, he dinitrile hydrogenation ki te hexdiamine me te nickel catalyst.
Te whakamahi carbide silicon, α-alumina ranei hei tautoko (me te iti o te waikura barium hei cocatalyst).I muri i te whakapai tonu o te whakakorikori me nga tikanga tukanga, kua neke ake te taumaha o te ethylene i te 100%.
He whakakōkī i maputia ki te silicon carbide, corundum ranei mo te hāora o-xylene ki te phthalic anhydride.He whakakōkī i mahia mā te rehu i te wāhanga kaha o te waikura raupapa vanadium-molybdenum ki te corundum mo te hāoratanga o te benzene, butane ranei ki te maleic anhydride.Ko te whakapai ake o tenei momo whakakorikori ko te whanaketanga o nga waahanga-maha, e waru nga waahanga whakakorikori kua puta.Ka huri ano te ahua o te kaikawe mai i te porowhita ki te porowhita, te porowhita kia pai ai te whakawhiti wera.Ko te tikanga whanui ko te whai i te kawenga nui, te hua nui me te tino ma o nga hua.
Pērā i te waikura methanol ki roto i te formaldehyde me te hiriwa – te pumice (te konumohe ranei), te waikura rino – te waikura molybdenum me te whakakōkī hiriwa hiko.
I te tekau tau atu i 1960, i hangaia he whakakorikori kei roto te bismuth-mo-phosphorus pūhui waikura whakakōkī.Ka taea te whakahiato i te Acrylonitrile i te taahiraa kotahi ma te taapiri i te propylene, te haukini me te hau ki runga i te whakakorikori.Hei whakapai ake i te whiriwhiringa me te whakaputa me te whakaiti i te parahanga o te taiao, kei te whakapai tonu nga momo whenua i te whakakorikori, a, kei etahi momo whakakorikori hou ki te 15 nga momo huānga.Ko te whakakōkī hāora pūhaumāota, te 60's whakawhanake parahi pūhaumāota alumina whakakōkī, i roto i te pire moenga wīwī i roto i te ethylene, hauwai pūhaumāota me te hau hāora ranei e taea te tiki dichloroethane.Ko te Dichloroethane i pirolyzed hei whakaputa i te monomer vinyl chloride.He painga tenei tikanga mo te whakawhanaketanga o te PVC i nga waahi e utu nui ana te hiko me te whakawhanaketanga o te petrochemical, te tikanga hanga tautoko me te whakakorikori.Ko etahi atu penei i te pakaru penehīni para, te nitrobenzene hydrogenation reduction ki te aniline, hydrogenation catalyst.
He whakakōkī hāora wā wai
Ko te nuinga:
(1) Ethylene, propylene oxidation acetaldehyde, acetone (Wacker tikanga), me te iti o te palladiumpūhaumāota pūhaumāota pūhaumāota wairewa whakakōkī, i roto i te olefin, hau hāora ranei, i muri i te kotahi e rua ranei nga kaupae o te tauhohenga ki te tiki i te e hiahiatia ana.pūhui whai hāora.Ko te kino ko te pirau kino o nga taputapu tauhohenga.
(2) Te hāora mekameka taha kakaramō te whakakōkī waikawa aryl, pēnei i te p-xylene i roto i te wairewa waikawa acetate me te acetate cobalt me te iti o te haukinia bromide.whakawera, hau hāora production waikawa terephthalic, engari te waikura nui o taputapu tauhohenga.
