  • Ethyl Ethanol

    Ethyl Ethanol

    Ethanol, paub los ntawm cov qauv tshuaj molecular C2H5OH lossis EtOH, yog xim tsis muaj xim, pob tshab, nplaim taws thiab cov kua hluav taws xob.Ethanol uas nws cov feem ntau tshaj li 99.5% yog hu ua anhydrous ethanol.Ethanol yog ib hom cawv, yog qhov tseem ceeb ntawm cawv, feem ntau hu ua cawv, nws yog cov nplaim taws, qhov tsis tshua muaj xim tsis muaj pob tshab ntawm cov kua hauv chav sov, qhov ntsuas cua, nws cov dej tov tau muaj qhov tshwj xeeb, ntxhiab tsw qab, thiab me ntsis ua kom tsis haum.Ethanol tsis tshua ntom dua li dej thiab tuaj yeem sib cuam tshuam ntawm txhua tus nqi. Soluble hauv dej, methanol, ether thiab chloroform.Nws tuaj yeem yaj ntau cov organic sib txuas thiab qee qhov sib xyaw ua ke.

  • Ethyl Acetate(≥99.7%)

    Ethyl Acetate ≥ .799.7%)

    Ethyl acetate yog xim tsis muaj pob tshab ua kua nrog lub txiv ntsej muag thiab muaj qhov tsis haum.Qhov kub siab -83 ℃, kub taw tes 77 ℃, qhov ntsuas tsis ua haujlwm 1.3719, nyem qhov taw tes 7.2 ℃ (qhib lub khob), nplaim taws, tuaj yeem tsis haum nrog chloroform, ethanol, acetone thiab ether, soluble hauv dej, tab sis kuj nrog qee cov kuab tshuaj los ua azeotrope sib tov.

  • 1,6-Hexanediol

    1,6-Hexanediol

    1, 6-hexadiol, tseem hu ua 1, 6-dihydroxymethane, lossis HDO rau luv, muaj cov qauv molecular ntawm C6H14O2 thiab molecular hnyav ntawm 118.17. Thaum sov sov chav, nws yog xim dawb waxy khoom, soluble hauv ethanol, ethyl acetate thiab dej, thiab muaj tsawg toxicity.
