99.95% Tetrahydrofuran (THF) CAS 109-99-9

Tetrahydrofuran tuaj yeem tawg thaum sib xyaw nrog huab cua;nws tuaj yeem tsim tawg peroxide nyob rau hauv cov huab cua, uas yog flammable nyob rau hauv cov ntaub ntawv ntawm qhib nplaim taws, kub thiab oxidant;burning ua irritating pa taws.Nws yog heterocyclic organic compound.Nws belongs rau ethers thiab yog ua tiav hydrogenation khoom ntawm cov aromatic compound furan.Nws yog siv los ua ib qho nruab nrab polar aprotic hnyav hauv tshuaj lom neeg cov tshuaj tiv thaiv thiab extractions.Tetrahydrofuran yog ib feem miscible nrog dej nyob rau hauv chav tsev kub, thiab ib co unscrupulous reagent manufacturers siv qhov no kom tau nyiaj loj los ntawm kev ntxiv dej rau tetrahydrofuran reagent.Tetrahydrofuran yooj yim hloov mus rau hauv peroxide thaum khaws cia.Yog li ntawd, kev lag luam tetrahydrofuran feem ntau tiv thaiv oxidation nrog BHT, 2,6-Di-tert-butyl-4-methylphenol.Tetrahydrofuran tuaj yeem khaws cia rau hauv lub vial kaw nrog sodium hydroxide hauv qhov chaw tsaus.

Tetrahydrofuran muaj cov yam ntxwv ntawm cov tshuaj toxicity tsawg, qis boiling point thiab zoo fluidity.Nws yog ib qho tseem ceeb raw khoom rau cov organic synthesis thiab cov kuab tshuaj zoo heev.Nws muaj ntau yam kev siv.Tetrahydrofuran muaj solubility zoo rau ntau cov organic tshuaj.Tag nrho cov organic tebchaw uas tsis yog propylene thiab fluororesins, tshwj xeeb tshaj yog rau polyvinyl chloride, polyvinylidene chloride, thiab aniline, muaj ib tug zoo dissolving nyhuv, thiab yog dav siv raws li qhov tsim nyog hnyav rau cov tshuaj tiv thaiv, uas yog hu ua "universal hnyav".
