三. Isicelo
1. Njengesinyibilikisi esiqhelekileyo,Tetrahydrofuranisetyenziswa ngokubanzi kwiingubo zomphezulu, iingubo ezikhuselayo, ii-inki, ii-extractants kunye nokuphathwa kwendawo yesikhumba sokwenziwa.
2.Tetrahydrofuranyimathiriyeli ekrwada ebalulekileyo yokuveliswa kwe-PTMEG kunye ne-solvent ephambili kwishishini lamayeza.
四.Impahla
Tetrahydrofuranlulwelo olungenambala olucacileyo olunevumba le-ether. Iyaxubana namanzi, utywala, iacetone, benzene, ester, ether kunye nehydrocarbon.
五.Ukuphatha kunye noGcino
1. Izilumkiso zokuphatha ngokukhuselekileyo
Kuphephe ukudibana nolusu namehlo. Kuphephe ukuphefumla umphunga okanye inkungu.
Gcina kude kwimithombo yokutshisa - Akukho kutshaya. Thatha amanyathelo okuthintela ukwakhiwa kwe-electrostatic
intlawulo.
2. Imiqathango yokugcina ngokukhuselekileyo, kuquka nakuphi na ukungahambelani
Gcina kwindawo epholileyo. Gcina isikhongozeli sivalwe ngokuqinileyo kwindawo eyomileyo nengena umoya. Izikhongozeli ezivulwayo kufuneka ziphinde zivaliwe kwaye zigcinwe zime nkqo ukuthintela ukuvuza.
Intsalela eyomileyo iyaqhuma. Gcina phantsi kwegesi engasebenziyo. Vavanya ukubunjwa kweperoxide ngamaxesha athile nangaphambi kokuba idistillation.
