Izici ezithinta iphuzu elibilayo le-tetrahydrofuran kanye nezicelo ezisebenzayo
I-Tetrahydroforan (thf) i-organic solvent esetshenziswa kabanzi embonini yamakhemikhali enesixazululo esiphakeme kanye nobuthi obuphansi, ngakho-ke isetshenziswe kabanzi emikhakheni yezemithi, amakhemikhali kanye nesayensi yezinto zokwakha. Kuleli phepha, sizoxoxa ngokujulile izici eziyisisekelo zephuzu elibilayo le-tetrahydrofoforuran, izici ezithinta lokho futhi zibaluleke kakhulu ezinhlelweni ezisebenzayo.
I. Izakhiwo eziyisisekelo zeTetrahydrofuran kanye nephuzu lazo elibilayo
I-Tetrahydroforan (thf) iyi-ether ye-cyclic ngefomula yamakhemikhali c4h8o. Njenge-solvent esetshenziswa kakhulu, i-tetrahydroforan iwuketshezi olungenamibala futhi olubonakalayo emazingeni okushisa asekamelweni futhi linokuqina okuphezulu. I-Tetrahydroforan inendawo ebilayo ecishe ibe ngu-66 ° C (cishe ama-339 k), okwenza kube lula ukuhwamuka futhi kubuye kube nezinqubo eziningi zamakhemikhali. I-Tetrahydroforuran ephansi ye-boiling ephansi futhi isho ukuthi ingasuswa ohlelweni lokuphendula ngokushesha, kunciphisa ukuphazamiseka ngokuphendula okulandelayo.
Izici ezithinta iphuzu elibilayo le-tetrahydrofuran
Yize iphuzu elibilayo le-tetrahydrofuran linenani elinqunyelwe ezincwadini zamakhemikhali, ekuzijwayeze indawo ebilayo ye-tetrahydrofuran ingathinteka yizici eziningi:
Ithonya lokucindezela okukhona: iphuzu elibilayo le-tetrahydrofuran liyahlukahluka ngengcindezi. Ekucindezelweni okujwayelekile komkhathi, iphuzu elibilayo le-tetrahydrofuran lingu-66 ° C. Ngaphansi kwengcindezi ephezulu noma ephansi, iphuzu elibilayo lizoshintsha ngokufanele. Ngokuvamile, ukukhuphuka kwengcindezi, kukhuphuka iphuzu elibilayo le-tetrahydrofuran; Ngakolunye uhlangothi, endaweni evulekile, iphuzu elibilayo lizokwehla.

Ithonya Lokumsulwa: Ukungcola eTetrahydrofuran kuzoba nomthelela endaweni yaso ebilayo. Uma isixazululo se-tetrahydroforuran siqukethe inani eliphakeme lamanzi noma okunye ukungcola kwe-solvent, iphuzu laso elibilayo lingahluka kulolo lwe-tetrahydrofuran emsulwa. Ikakhulu, ukuba khona komswakama, okuncibilikayo kancane emanzini, kungakha i-azeotrope nge-thf, okuholela ekushintsheni okuncane ngephuzu elibilayo.

I-Azeotropic Phenomena: Ekusebenzeni, i-tetrahydroforunan imvamisa ihlanganiswa namanye ama-solvents ukwakha ama-azeotropic mixtures. Amaphoyinti abilayo ezinhlamvu ezinjengalezi ajwayele ukwehluka kulawo wezinto ezizodwa kanye ne-azeotropy afaka inqubo yokuhlukanisa. Ngakho-ke, lapho ukhetha i-tetrahydroforunan njenge-solvent, kubalulekile ukuqonda indlela yayo yokuziphatha kwe-azeotropic nezinye izinhlanganisela.

III. Ukusetshenziswa okusebenzayo kweTetrahydrofuran Booling Point embonini
Izakhiwo ze-Boiling Point of Tetrahydrofuran zinezicelo ezibalulekile ekukhiqizeni amakhemikhali:
Ukubuyisa futhi kuphinde kusetshenziswe ama-solvents: Njengoba i-tetrahydroforunan inendawo evuthayo ephansi, kulula ukutholwa kwinhlanganisela yokusabela ngokudilisha noma amanye amasu wokuhlukanisa. Le mpahla ayisizi kuphela ukunciphisa izindleko zokukhiqiza, kepha futhi inciphisa umthelela emvelweni.

Izicelo ku-polymerication: Esikhathini esithile sokuphendula kwe-polymerication, i-tetrahydroforan inendawo evumayo yokubilisa, evumela ukuthi ilawula ngempumelelo izinga lokushisa futhi liqinisekise ukuthi ukusabela kuqhubeka kahle. Ukuguquguquka kwalo kungasuswa ngokushesha ekugcineni kokusabela, ukuvimbela imiphumela emibi ekuhlanzekeni komkhiqizo.

Isicelo ekuhlanganiseni izidakamizwa: I-Tetrahydroforunan imvamisa isetshenziswa njenge-solvent enqubweni yokuhlanganiswa kwezidakamizwa, iphuzu layo elibilayo lilinganiselwe, elivumelana nokulawulwa okuqondile kwezimo zokuphendula. Izakhiwo ezisheshayo zeTetrahydrofuran zikwenza isebenze kakhulu ekuhlukanisweni kokuhlala kwezokusabela kwangemva kokuhlanzwa kanye nezinqubo zokuhlanza.

Ukugcina
Iphoyinti elibilayo leTetraHyDrofofon lingenye yezindawo ezibalulekile ezisetshenziselwa izimboni. Ukuqonda iphuzu elibilayo le-tetrahydroforuran kanye nezinto zalo ezinethonya kungasiza izinkampani zamakhemikhali ukuba zilawule kangcono izimo zokuphendula ekukhiqizweni kwangempela futhi zithuthukise ukusebenza kwekhwalithi nokukhiqizwa kwemikhiqizo. Ukusetshenziswa okunengqondo kwezici zayo eziphansi ze-BOAGH POINT Izici kungasiza ukufeza kabusha kabusha kwezinsizakusebenza nokuthuthuka okuqhubekayo kwemvelo. Lapho ukhetha futhi usebenzisa i-Tetrahydroforunan njenge-solvent, ukucubungula okugcwele kwezimpawu zayo ezibilayo kanye nezinto ezinethonya kuyisihluthulelo sokuqinisekisa ukuphepha nokusebenza kahle kwezinqubo zamakhemikhali.
