三. Application
1.Sechinhu chinowanzogadziriswa,Tetrahydrofuraninoshandiswa zvakanyanya mumucheka wepamusoro, kuvhara kwekudzivirira, inki, zvinyorwa uye kushandiswa kwepamusoro kweganda rekugadzira.
2.Tetrahydrofuranchinhu chakakosha mbishi pakugadzirwa kwePTMEG uye iyo huru solvent yeindasitiri yemishonga.
四.Property
Tetrahydrofuranimvura inoonekera isina ruvara ine hwema hweether. Inosanganiswa nemvura, doro, acetone, benzene, ester, ether uye hydrocarbon.
五.Kubata uye Kuchengeta
1. Chengetedzo yekubata zvakachengeteka
Dzivisa kusangana neganda nemaziso. Dzivisa kufema kwemhute kana mhute.
Ramba kure nepanobatidza moto - Hapana kuputa. Tora matanho ekudzivirira kuwanda kwe electrostatic
charge.
2. Mamiriro ekuchengetedza akachengeteka, kusanganisira chero kusawirirana
Chengeta munzvimbo inotonhorera. Chengeta chigadziko chakavharwa zvakasimba munzvimbo yakaoma uye ine mhepo yakanaka. Magaba anenge akavhurwa anofanirwa kunyatsovharwa uye kugara akati twasu kudzivirira kudonha.
Dry residue inoputika. Chengetedza pasi pegesi inert. Edzai maumbirwo eperoxide nguva nenguva uye musati maita distillation.
