三. Isicelo
1.Ngokuba i-solvent ejwayelekile,TetrahydroforunanIsetshenziswa kabanzi embozweni ongaphezulu, izimbobo ezivikelayo, ama-inks, ama-extractants kanye nokwelashwa komhlaba kwesikhumba sokufakelwa.
2.TetrahydroforunanIngabe impahla ebalulekile eluhlaza ekhiqizwayo ye-PTMeG kanye ne-solvent eyinhloko embonini yezemithi.
四 .Izimpawu
Tetrahydroforunanuketshezi olungenamibala ngephunga le-ether. Akubukeki ngamanzi, utshwala, i-acetone, i-benzene, ester, ether kanye ne-hydrocarbon.
五 .Ukugcina nokugcina
1. Ukuqapha kokuphatha okuphephile
Gwema ukuxhumana nesikhumba namehlo. Gwema ukuphefumula komoya noma inkungu.
Gcina kude nemithombo yokulahla - azikho izinyathelo zokubhema.Take ukuvimbela ukwakhiwa kwe-electrostatic
Shaja.
2. Izimo zesitoreji esiphephile, kufaka phakathi noma yikuphi ukungahambisani
Gcina endaweni epholile. Gcina isitsha esivalwe ngokuqinile endaweni eyomile futhi enomoya. Iziqukathi ezivuliwe kufanele zithathwe ngokucophelela futhi zigcinwe ziqonde ukuvikela ukuvuza.
Izinsalela ezomile ziqhuma. Gcina ngaphansi kwegesi ye-inert. Hlola ukwakheka kwe-peroxide ngezikhathi ezithile nangaphambi kokufakwa.
