propylene oxidewaa nooc ka mid ah alaabta ceeriin kiimikaad organic muhiim ah iyo dhexdhexaad ah. Waxaa inta badan loo adeegsadaa isku dhafka polyols-ka, polyester polyols, polyurethane, polyether amine, iwm. Propylene oxide waxa kale oo loo isticmaalaa sida walxo ceeriin ah oo lagu diyaariyo noocyada kala duwan ee surfactants, daroogooyinka, kiimikooyinka beeraha, iwm, waana mid ka mid ah alaabta ceeriin ee muhiimka ah ee warshadaha kiimikada.

Propylene oxide waxa lagu soo saaraa oksaydhaynta propylene oo leh kiciye. Propylene alaabta ceeriin waxaa lagu qasaa hawo ciriiri ah ka dibna la dhex mariyo reactor ka buuxsamay kicinta. Heerkulka falcelinta guud ahaan waa 200-300 DEG C, cadaadiskuna waa qiyaastii 1000 kPa. Alaabada falcelinta waa isku dhafka ka kooban propylene oxide, carbon dioxide, carbon monoxide, biyo iyo xeryahooda kale. Dareeraha loo isticmaalo falcelintan ayaa ah kicinta oksaydhka birta ee kala-guurka ah, sida kicinta oksaydhka silver, chromium oxide kisheeyaha, iwm. Xulashada kicinta kuwan propylene oxide waa mid aad u sareysa, laakiin hawshu waa yar tahay. Intaa waxaa dheer, kicinta lafteeda ayaa la demi doonaa inta lagu jiro falcelinta, markaa waxay u baahan tahay in dib loo soo nooleeyo ama la beddelo si joogto ah.

Kala-soocidda iyo nadiifinta propylene oxide ee isku-dhafka falcelinta ayaa ah tallaabooyin aad muhiim u ah habka diyaarinta. Habka kala-soocidda guud ahaan waxaa ka mid ah biyo-dhaqidda, nadiifinta iyo tillaabooyinka kale. Marka hore, isku darka falcelinta waxaa lagu dhaqaa biyo si meesha looga saaro qaybaha karkaraya sida propylene iyo carbon monoxide. Kadibna, isku dar ah ayaa la nadiifiyaa si loo kala saaro oxide propylene iyo qaybaha kale ee karkarin kara. Si loo helo propylene oxide saafi ah oo sarreeya, waxaa loo baahan karaa tillaabo nadiifin dheeraad ah sida adsorption ama saarista.

Guud ahaan, diyaarinta propylene oxide waa nidaam adag, kaas oo u baahan tallaabooyin badan iyo isticmaalka tamarta sare. Sidaa darteed, si loo yareeyo kharashka iyo saameynta deegaanka ee habkan, waxaa lagama maarmaan ah in si joogto ah loo hagaajiyo tignoolajiyada iyo qalabka habka. Waqtigan xaadirka ah, cilmi-baarista hababka cusub ee loogu talagalay diyaarinta oxide propylene inta badan waxay diiradda saartaa hababka deegaanka saaxiibtinimo leh isticmaalka tamarta yar iyo waxtarka sare leh, sida oxidation catalytic iyadoo la adeegsanayo oksijiinta molikula sida oxidant, habka oksaydhka ee microwave-ka caawiyay, habka oksaydhka supercritical, iwm.
