I-Tetrahydrofuraniyinhlanganisela yamakhemikhali ene-molecular formula C4H8O. Iwuketshezi olungenambala, oluvuthayo olunephunga elimnandi elipholile. Lo mkhiqizo uyincibilikisi evamile ezimbonini ezihlukahlukene, okuhlanganisa ezemithi, amapulasitiki, kanye nokukhiqizwa kwe-polymer. Nakuba inezinye izingozi ezingase zibe khona, jikelele, i-Tetrahydrofuran ayiwona umkhiqizo oyingozi.
Ingozi eyodwa engaba khonaI-Tetrahydrofuranukuvutha kwayo. Uketshezi lune-flashpoint engu -14°C futhi lungavutha kalula uma luhlangana nenhlansi, ilangabi noma ukushisa. Kodwa-ke, lobu bungozi bungalawuleka ngokulandela izinqubo eziphephile zokulondoloza nokuphatha. Ukunciphisa ingozi yomlilo nokuqhuma, kubalulekile ukugcina umkhiqizo kude nemithombo yokuthungela nokusebenzisa umoya ofanele.
Enye ingozi engenzeka yeI-Tetrahydrofuranyikhono layo lokubangela ukucasuka kwesikhumba kanye nokushiswa kwamakhemikhali. Lapho uketshezi luthintana ngqo nesikhumba, lungabangela ukucasuka, ububomvu, nokuvuvukala. Le ngozi ingancishiswa ngokugqoka izingubo ezifanele kanye nezinto zokuzivikela ngenkathi uphatha umkhiqizo. Amagilavu, izibuko, nezingubo zokuzivikela kungavimbela ukuchayeka kwesikhumba.
I-Tetrahydrofuranfuthi iwuketshezi oluguquguqukayo, okusho ukuthi ingahwamuka kalula futhi yethule ingozi yokuhogela. Ukuchayeka emhwamukeni isikhathi eside kungaholela ekubeni nesiyezi, ikhanda elibuhlungu nezinkinga zokuphefumula. Kodwa-ke, lobu bungozi bungagwenywa ngokusebenzisa umkhiqizo endaweni enomoya omuhle kanye nokugwema ukuchayeka isikhathi eside.
Naphezu kwalezi zingozi ezingaba khona, i-Tetrahydrofuran iwumkhiqizo owusizo kakhulu. Ivame ukusetshenziswa embonini yezemithi njenge-solvent yezithako ezisebenzayo. Kubuye kube yi-solvent ebalulekile ekukhiqizeni ama-polymers namapulasitiki, lapho kunika amandla ukulawula okunembile kwezimo zokucubungula kanye nezakhiwo zokugcina zomkhiqizo.
Ngaphezu kwalokho, lo mkhiqizo kulula ukuwuphatha futhi unobuthi obuphansi. Kuboniswe ukuthi kunamazinga aphansi obuthi ezifundweni zezilwane, okwenza kuphephe ukusetshenziswa ezinqubweni zokukhiqiza ezilawulwayo. Lo mkhiqizo futhi uyabola, okusho ukuthi uqhekeka ngokwemvelo ube yizinto ezingenabungozi ngokuhamba kwesikhathi.
Sengiphetha, kuyilapho zikhona izingozi ezihlobeneI-Tetrahydrofuran, lezi zingozi zingalawulwa ngokulandela izinqubo zokuphatha nokugcina ngokuphephile. Ngokusetshenziswa kwayo kabanzi ezimbonini ezihlukahlukene kanye nobuthi bayo obuphansi kakhulu, i-Tetrahydrofuran iwumkhiqizo ophephile nobalulekile odlala indima ebalulekile ezinqubweni zokukhiqiza zanamuhla. Uma nje isetshenziswa ngendlela efanele, asikho isizathu sokuyibheka njengomkhiqizo oyingozi.
