Mtengo Wabwino Wopanga PERCHLOROETHYLENE CAS:127-18-4

kufotokozera mwachidule:

PERCHLOROETHYLENE： imadziwikanso kuti chloride yonse. Ponena za kapangidwe ka mamolekyulu, mankhwala opangidwa ndi maatomu onse a haidrojeni mu ethylene adasinthidwa ndi chlorine. Mu 1821, nthawi yoyamba idapangidwa ndi kuwonongeka kwa kutentha kwa FaraDay. Madzi owonekera opanda utoto. Pali fungo lofanana ndi ether. Losayaka.

Kulemera kwa mamolekyulu 165.85. Kuchulukana kwa 1.6220. Kusungunuka -22.7 ℃. Kuwira 121.2 ℃, 33.2 ℃ (4.000 × 103Pa). Chizindikiro cha refractive ndi 1.5055. Kukhuthala ndi 0.839MPA · s (20 ° C). Kuthamanga kwa nthunzi (× 103Pa): 5.466 (40 ° C), 13.865 (60 ° C), 30.131 (80 ° C), 58.128 (100 ° C). Tetthylene sisungunuka mu shuga, glycerin ndi mapuloteni, ndipo imasungunuka pang'ono m'madzi (0.015 pamene 25 ° C), yomwe imatha kusungunuka ndi ethanol, ether, chloroform, benzene, ndi chlorine organic solvents. Sizimasungunuka ndi hydrolyzed. CHEMICALBOOK ikadali yokhazikika pa 500 ° C ngati pali mpweya wopanda mpweya, chinyezi komanso palibe ma catalyst. Tethelhyloethane imatha kupangidwa ikapangidwa ndi hydrogenation. Tiroroethane imapangidwa panthawi ya chloride. Tetrachloride imathanso kuchitapo kanthu ndi bromine kuti ipange bromine sea chlorine kapena diptide chloride. Pogwira ntchito ya catalyst, imathanso kuchitapo kanthu ndi hydrogen fluoride. Pokhala ndi kuwala, mpweya, ndi madzi kwa nthawi yayitali, imasungunuka pang'onopang'ono kukhala trichloride ndi kuwala, pomwe zitsulo zowononga monga chitsulo, aluminiyamu, ndi zinc zimatha kuchepetsedwa ndi zokhazikika. Ngati pali mpweya woyatsidwa, umatenthedwa mpaka 700 ° C kuti uwole kukhala hex chloride ndi hex chlorine. Tethalothene imatha kusungunuka ndi oxidant wamphamvu. Teththyl chloride imatha kukhala ndi zotsatira zoyipa za mankhwala ndi ufa wa pinki, pinki, lithium dandruff, tetraoxide, ndi sodium hydroxide. Tetrachloride ndi poizoni ndipo ndi choletsa chapakati cha mitsempha, chomwe chingayambitse mutu, nseru, kusanza, komanso ngakhale chikomokere. Mbewa ndi LD508850mg/kg. Kuchuluka kovomerezeka kwa malo ogwirira ntchito ndi 100 × 10-6.

Kugwiritsa ntchito PERCHLOROETHYLENE

Mu mafakitale, PERCHLOROETHYLENE imagwiritsidwa ntchito kwambiri ngati zosungunulira, kupanga zinthu zachilengedwe, chotsukira pamwamba pa zitsulo ndi chotsukira chouma, desulfurizer, ndi chosinthira kutentha. Imagwiritsidwa ntchito pachipatala ngati anthelmintic. Ndiwonso pakati pa trichloroethylene ndi zinthu zachilengedwe zosungunuka. Anthu wamba amatha kukhala ndi tetrachloroethylene yochepa kudzera mumlengalenga, chakudya ndi madzi akumwa. Tetrachloroethylene ili ndi kusungunuka kwabwino kwa zinthu zambiri zosapangidwa ndi organic, monga sulfure, ayodini, mercuric chloride, aluminiyamu chloride, mafuta, rabara ndi resin, kusungunuka koteroko kumagwiritsidwa ntchito kwambiri ngati chotsukira chochotsa mafuta chachitsulo, chotsukira utoto, chotsukira chouma, chosungunulira rabara, chosungunulira inki, sopo wamadzimadzi, chotsukira ubweya wapamwamba ndi nthenga; Tetrachloroethylene imagwiritsidwanso ntchito ngati chothamangitsa (hookworm ndi ginger worm); chotsukira chomaliza cha kukonza nsalu.
1. Amagwiritsidwa ntchito ngati zosungunulira zachilengedwe, chotsukira chouma, chotsukira mafuta, chotsukira utsi, chotsukira sulfurizer ndi chotsukira nsalu, ndi zina zotero.
2. Tetrachloroethylene imagwiritsidwa ntchito kwambiri, makamaka ngati zosungunulira zachilengedwe, chotsukira chouma, chosungunulira zitsulo, komanso ngati choletsa tizilombo toyambitsa matenda. Tetrachloroethylene ingagwiritsidwe ntchito ngati chotsitsa mafuta, chozimitsira moto komanso chotchingira utsi, ndipo ingagwiritsidwenso ntchito popanga trichloroethylene ndi mankhwala achilengedwe okhala ndi fluorine.
3. Amagwiritsidwa ntchito ngati zosungunulira zachilengedwe, chotsukira chouma, chotsukira sulfurizer ndi chotsukira nsalu
4. Tetrachloroethylene imagwiritsidwa ntchito kwambiri, makamaka ngati zosungunulira zachilengedwe, chotsukira chouma, chosungunulira zitsulo, chomwe chimagwiritsidwanso ntchito ngati chosungunulira mankhwala chochotsa tizilombo toyambitsa matenda, komanso ngati zinthu zoyeretsera chromatographic analysis standard. Tetrachloroethylene ingagwiritsidwe ntchito ngati chotsitsa mafuta, chozimitsira moto komanso chotchingira utsi, komanso ingagwiritsidwe ntchito popanga trichloroethylene ndi mankhwala achilengedwe okhala ndi fluorine.
5. Chosungunulira chomwe chimagwiritsidwa ntchito ngati mafuta kapena chinthu chonga mafuta mu kusanthula kwachilengedwe. Chotsukira chamadzimadzi cha chromatography chopanikizika kwambiri. Chosungunulira chowunikira spectrophotometric. Kapangidwe kachilengedwe.
