1.I-hydration catalyst

I-hydration yindlela yokusabela lapho amanzi ehlangana nenye into yakhe i-molecule eyodwa.Ama-molecule amanzi ane-hydrogen ne-hydroxyl yawo kanye nama-molecule we-unsaturated bond ahlanganisa ukwakha izinhlanganisela ezintsha, kule nqubo idlala indima ekhuthazayo entweni ebizwa ngokuthi i-hydration catalyst, le ndlela yokuhlanganiswa iye yasetshenziswa ekukhiqizeni amakhemikhali e-organic.Inqubo ye-hydration ingenye yezindlela ze-organic synthesis, kodwa njengendlela yokukhiqiza ebalulekile, inqunyelwe ezinhlotsheni ezimbalwa zemikhiqizo, njenge-ethanol nama-diols.

2.I-Dehdration Catalst

Ukukhipha amanzi emzimbeni kungenziwa ngokushisisa noma nge-catalyst noma ngokusabela nge-ejenti eqeda amanzi emzimbeni.Ukusabela kokuphelelwa amanzi emzimbeni kuyinkqubo ehlehlayo yokusabela kwe-hydration, ngokuvamile ukusabela kwe-endothermic, ngokuvamile, izinga lokushisa eliphezulu nokucindezela okuphansi kuyasiza ekuphenduleni.Ngaphezu kwalokho, iningi lenqubo yokuqeda amanzi emzimbeni kufanele yenziwe phambi kwama-catalysts.I-catalyst esetshenziselwa inqubo ye-hydration - i-acid catalyst ibuye ifanele ukuphelelwa amandla kwamanzi, evame ukusetshenziswa yi-sulfuric acid, i-phosphoric acid, i-aluminium oxide nokunye.Ama-catalyst ahlukene anemikhiqizo eyinhloko ehlukene kanye nokukhetha okuphezulu.

3.I-Alkylation Catalyst

I-alkylation ukudluliselwa kweqembu le-alkyl lisuka kwelinye i-molecule liye kwelinye.Ukusabela lapho iqembu le-alkyl (i-methyl, i-ethyl, njll.) lethulwa ku-molecule ehlanganisiwe.Ama-alkylation agents avame ukusetshenziswa embonini i-olefin, i-halane, i-alkyl sulfate ester, njll.

Enqubweni evamile yokucwenga, uhlelo lwe-alkylation luhlanganisa ama-alkenes esisindo samangqamuzana aphansi (ikakhulukazi i-propylene ne-butene) ne-isobutane esebenzisa i-catalyst (i-sulfonic noma i-hydrofluoric acid) ukwenza ama-alkylates (ikakhulukazi ama-octane aphezulu, ama-alkanes aseceleni).Ukusabela kwe-alkylation kungahlukaniswa ku-alkylation eshisayo kanye ne-catalytic alkylation.Ngenxa yokushisa okuphezulu kokusabela kwe-alkylation eshisayo, kulula ukukhiqiza i-pyrolysis nokunye ukusabela ohlangothini, ngakho-ke indlela ye-catalytic alkylation iyamukelwa embonini.

Ngenxa yokuthi i-sulfuric acid ne-hydrofluoric acid ine-asidi eqinile, ukugqwala kwemishini kubi kakhulu.Ngakho-ke, ngokombono wokukhiqiza okuphephile nokuvikelwa kwemvelo, lezi zisusa ezimbili aziwona ama-catalysts afanelekile.Njengamanje, i-superacid eqinile isetshenziswa njenge-alkylation catalyst, kodwa ayikakafinyeleli esigabeni sokusetshenziswa kwezimboni kuze kube manje.

4.I-Isomerization Catalyst

Ukuguqulwa kwe-isomer eyodwa nenye.Inqubo yokushintsha ukwakheka kwenhlanganisela ngaphandle kokushintsha ukwakheka kwayo noma isisindo samangqamuzana.Ushintsho endaweni ye-athomu noma yeqembu ku-organic compound molecule.Ngokuvamile phambi kwama-catalysts.

5.I-Disproportionation catalyst

Uhlobo olulodwa lwe-hydrocarbon lungashintshwa lube izinhlobo ezimbili ze-hydrocarbon ehlukene ngokusebenzisa inqubo yokuhlukanisa, ngakho-ke ukungafani kungenye yezindlela ezibalulekile zokulawula ukuhlinzekwa kanye nokufunwa kwe-hydrocarbon embonini.Izinhlelo zokusebenza ezibaluleke kakhulu ukungafani kwe-toluene ukuze kukhuliswe ukukhiqizwa kwexylene nokukhiqiza i-benzene ehlanzekile ngesikhathi esisodwa, nokuhlukaniswa kwe-propylene ukukhiqiza izinqubo ze-triolefin ze-polymer-grade ethylene kanye ne-high purity butene.Ukuguqulwa kwe-toluene ibe yi-benzene nexylene ngokuvamile kusebenzisa i-silicon aluminium catalyst.Njengamanje, ucwaningo oludume kakhulu yi-molecular sieve catalyst, njenge-meridionite-type silk molecular sieve.
