PCE (Tetrachloroethylene), tseem hu ua perchloroethylene, yog ib hom ethylene chloride compound nrog cov tshuaj formula Cl₂C=CCl₂ thiab molecular hnyav ntawm 165.8. Nws muaj qhov ntom ntom ntawm 1.62 g / cm³ thiab zoo li tsis muaj xim, pob tshab, thiab yooj yim ntws cov kua hauv chav sov. Nws yog nonflammable thiab muaj ib tug txawv tsw. Tetrachlorethylene yog me ntsis soluble hauv dej, nrog rau solubility ntawm 0.015 g ib 100 mL ntawm 20 degree, tab sis nws yog soluble nyob rau hauv organic solvents xws li ethanol thiab ether.
Lub compound yog incompatible nrog muaj zog oxidizing neeg sawv cev thiab tshuaj active hlau (xws li barium, lithium, thiab beryllium). Txawm hais tias tetrachlorethylene kuj ruaj khov, nws muaj zog heev nrog cov concentrated nitric acid, ua rau carbon dioxide.
Txoj kev tsim khoom:
Tetrachlorethylene tuaj yeem tsim los ntawm ntau txoj hauv kev, suav nrog cov txheej txheem ethylene, hydrocarbon oxidation, thiab txheej txheem acetylene.
Kev siv Perchlorethylene:
Qhov tseem ceeb siv ntawmperchlorethylene hnyavyog raws li cov tshuaj nruab nrab, thaum me me yog siv rau kev tu hlau, aerosol degreasing, qhuav tu, thiab textile ua. Nws kuj tseem ntxiv rau aerosols, hnyav soaps, inks, adhesives, sealants, polishes, lubricating oils, thiab silicone khoom.
