Isopropanolke motsoako o tloaelehileng oa organic o nang le ts'ebeliso e fapaneng, ho kenyeletsoa libolaea likokoana-hloko, lihlapolli le lisebelisoa tse tala tsa lik'hemik'hale. E na le mefuta e mengata ea lits'ebetso indastering le bophelong ba letsatsi le letsatsi. Leha ho le joalo, ho utloisisa ts'ebetso ea tlhahiso ea isopropanol ke ea bohlokoa haholo hore re utloisise hamolemo thepa le lits'ebetso tsa eona. Sengoliloeng sena se tla fana ka kenyelletso e qaqileng mabapi le ts'ebetso ea tlhahiso ea isopropanol le litaba tse amanang le eona.

'Mele oa mantlha:

1.Synthesis mokhoa oa isopropanol

Isopropanol e hlahisoa haholo ke hydration ea propylene. Propylene hydration ke mokhoa oa ho arabela propylene ka metsi ho hlahisa isopropanol tlas'a ketso ea catalyst. Li-Catalyst li bapala karolo ea bohlokoa ts'ebetsong ena, kaha li ka potlakisa sekhahla sa karabelo le ho ntlafatsa khetho ea sehlahisoa. Hajoale, li-catalyst tse sebelisoang hangata li kenyelletsa sulfuric acid, alkali metal oxides, le li-resin tsa ion exchange.

2.Mohloli oa propylene

Propylene haholo-holo e tsoa ho libeso tsa khale tse kang oli le khase ea tlhaho. Ka hona, ts'ebetso ea tlhahiso ea isopropanol e itšetlehile ka tekanyo e itseng ka mafura a mafura. Leha ho le joalo, ka tlhokomeliso e ntseng e eketseha ea ts'ireletso ea tikoloho le nts'etsopele ea matla a tsosolositsoeng, batho ba ntse ba hlahloba mekhoa e mecha ea ho hlahisa propylene, e kang ka ho belisoa ha likokoana-hloko kapa ho kopanya lik'hemik'hale.

3.Manufacturing process flow

Ts'ebetso ea tlhahiso ea isopropanol haholo-holo e kenyelletsa mehato e latelang: propylene hydration, catalyst recovery, ho arohana ha lihlahisoa, le ho hloekisa. Propylene hydration e etsahala ka mocheso o itseng le khatello, nakong eo motsoako o kenyelletsoang motsoako oa propylene le metsi. Ka mor'a hore karabelo e phethoe, catalyst e hloka ho khutlisoa ho fokotsa litšenyehelo tsa tlhahiso. Ho arohana ha lihlahisoa le ho ntlafatsa ke mokhoa oa ho arola isopropanol ho tloha motsoako oa karabelo le ho e hloekisa ho fumana sehlahisoa se phahameng sa bohloeki.

Qetello:

Isopropanol ke motsoako oa bohlokoa oa tlhaho o nang le lisebelisoa tse ngata. Ts'ebetso ea tlhahiso haholo-holo e kenyelletsa karabelo ea hydration ea propylene, mme catalyst e phetha karolo ea bohlokoa ts'ebetsong ena. Leha ho le joalo, ho ntse ho e-na le litaba tse amanang le mofuta oa catalyst e sebelisoang tlhahiso ea isopropanol le mohloli oa propylene, joalo ka tšilafalo ea tikoloho le tšebeliso ea lisebelisoa. Ka hona, re hloka ho tsoela pele ho hlahloba mekhoa e mecha ea tlhahiso le theknoloji ho finyella tlhahiso e tala, e sebetsang hantle le e tsitsitseng ea isopropanol.
