I-Tetraethylene glycol dimethyl ether ingasetyenziswa njenge-solvent egqwesileyo ye-alkaline yegolide ye-hydrides;
I-Tetraethylene glycol dimethyl ether isetyenziselwa kwiinkqubo ezahlukeneyo zokuphendula iikhemikhali ezifana ne-alkylation condensation kunye nokunciphisa;
Ngenxa yesiseko sayo se-Lewis, i-Tetraethylene glycol dimethyl ether inokukhetha ngokukhetha iigesi ze-acidic zokuhlanjululwa kwegesi ye-synthesis, igesi yendalo, i-acetylene, kunye nezinye iigesi; Igas chromatography kwisigaba esimileyo.
1. I-Tetraethylene glycol dimethyl ether (TEGDME) Sebenzisa izikhongozeli ezenziwe ngezinto ezifanelekileyo ezihambelana ne-TEGDME, njengeglasi okanye iiplastiki ezithile (umz., i-polyethylene ephezulu). Qinisekisa ukuba isikhongozeli sivalwe ngokuqinileyo ukunqanda ukungcoliseka kunye nokuba ngumphunga.
2. Zonke izikhongozeli kufuneka zibhalwe ngokucacileyo igama lekhemikhali, i-concentration, ingcaciso yengozi, nomhla ezifunyenwe ngawo. Oku kunceda ukuchonga into kwaye iqinisekise ukuphathwa ngokukhuselekileyo.
3. Gcina i-TEGDME kwindawo epholileyo, neyomileyo, kude nelanga kunye nobushushu. Ngokufanelekileyo, kufuneka igcinwe kwiqondo lokushisa, kodwa nceda ujonge iPhepha leDatha yoKhuseleko (SDS) kwiingcebiso ezithile zokugcina ukushisa.
4. Qinisekisa ukuba iindawo zokugcina zingena umoya kakuhle ukuthintela ukuqokelelwa komphunga, onokuba yingozi.
5. Gcina i-TEGDME kude nezinto ezingahambelaniyo ezifana ne-oxidants eqinile, i-acids kunye neziseko zokuthintela nakuphi na ukuphendula okuyingozi.
6. Ukufikelela kwiindawo zogcino kuthintelwe kuphela abasebenzi abaqeqeshiweyo kwaye kuqinisekiswe ukuba izixhobo zokhuseleko ezifanelekileyo (umz. iiglavu, iiglavu) zikhona zokuphatha imichiza.
7. I-Tetraethylene glycol dimethyl ether (TEGDME) Sebenzisa imilinganiselo yokulawula ukuchitheka, njengezinto ezifunxayo okanye iingxowa zokuchitheka, kwimeko yokuchitheka ngengozi okanye ukuvuza.
8. Ziqhelanise neenkqubo zongxamiseko xa kunokwenzeka ukuba kuvezwe okanye kuchitheke kwaye uqinisekise ukuba amaxwebhu edatha yokhuseleko afumaneka ngokulula.
