三. Karata yanchito
1.TetrahydroforanAmagwiritsidwa ntchito kwambiri pamtunda, zokutira zotchinga, inks, zowonjezera komanso kuzunzidwa kwa zikopa zopangidwa.
2.Tetrahydroforanndi chinthu chofunikira chopangira ptmeg ndi zosungunulira zazikulu zamakampani opanga mankhwala.
四 .Party
Tetrahydroforanndi fungo lowoneka bwino ndi fungo la ether. Ndizolakwika ndi madzi, mowa, acetone, benzene, erster, ethercarbon.
五. Heandling ndi kusungidwa
1. Kusamala kuti mugwiritse ntchito bwino
Pewani kulumikizana ndi khungu ndi maso. Pewani kupuma kwa nthunzi kapena mtengo.
Pewani kutali ndi magwero oyatsira - palibe ma stoking.Ake kuti mupewe kupanga magetsi
mlandu.
2. Mikhalidwe yosungirako bwino, kuphatikizapo zosagwirizana zilizonse
Sungani pamalo abwino. Sungani chidebe chotsekedwa bwino m'malo owuma komanso owuma. Zotengera zomwe zimatsegulidwa ziyenera kusinthidwa mosamala ndikusunga zowongoka kuti zisawonongeke.
Zouma zouma ndizophulika. Sungani pansi pa mpweya. Yesani mapangidwe a peroxide nthawi ndi nthawi komanso musanakhale distillation.
