Kaomi mahu (× 103Pa): 5.466 (40 ° C), 13.865 (60 ° C), 30.131 (80 ° C), 58.128 (100 ° C). ʻAʻole hiki ke hoʻoheheʻe ʻia ʻo Tetthylene i ke kō, glycerin a me ka protein, a he mea hoʻoheheʻe iki ia i ka wai (0.015 i ka 25 ° C), hiki ke hoʻoheheʻe ʻia me ka ethanol, ether, chloroform, benzene, a me nā mea hoʻoheheʻe organik chlorine. ʻAʻole i hydrolyzed. Paʻa mau ʻo CHEMICALBOOK ma 500 ° C ma lalo o ke alo o ka ea ʻole, ka makū a me nā mea hoʻouluulu ʻole. Hiki ke hoʻoulu ʻia ʻo Tethelhyloethane i ka wā o ka hydrogenation. Hoʻoulu ʻia ʻo Tiroroethane i ka wā o ka chloride. Hiki iā Tetrachloride ke hana pū me ka bromine e hana i kahi bromine ocean chlorine a i ʻole diptide chloride. Ma lalo o ka hana a kahi mea hoʻouluulu, hiki iā ia ke hana pū me ka hydrogen fluoride. Ma lalo o ke ola ʻana o ka mālamalama, ka ea, a me ka wai no ka manawa lōʻihi, ua hoʻoheheʻe mālie ʻia i trichloride a me ka mālamalama, ʻoiai hiki ke hoʻopau ʻia nā metala ʻawaʻawa e like me ka hao, alumini, a me ka zinc me nā mea hoʻopaʻa. Inā he kalapona i hoʻāla ʻia, hoʻomehana ʻia i 700 ° C e hoʻoheheʻe i ka hex chloride a me ka hex chloroline. Hiki ke hoʻopau ʻia ʻo Tethalothene e kahi oxidant ikaika. Hiki iā Tetthyl chloride ke loaʻa nā hopena kemika koʻikoʻi me ka pauka poni, poni, lithium dandruff, tetraoxide, a me ka sodium hydroxide. He mea ʻawahia ʻo Tetrachloride a he mea hoʻopaʻa i ke kikowaena o ke aʻalolo, hiki ke hoʻoulu i ka ʻeha poʻo, ka nausea, ka luaʻi, a me ka coma. ʻO ka ʻiole he LD508850mg/kg. ʻO ka nui o ka noʻonoʻo ʻana o ka wahi hana he 100 × 10-6.

Nā noi o PERCHLOROETHYLENE

I ka ʻoihana, hoʻohana nui ʻia ʻo PERCHLOROETHYLENE ma ke ʻano he solvent, organic synthesis, metal surface cleaner a me dry cleaner agent, desulfurizer, he mea hoʻoili wela. Hoʻohana ʻia ia ma ke ʻano he anthelmintic. He waena nō hoʻi ia o ka trichloroethylene a me nā mea ola fluorinated. Hiki i nā kamaʻāina maʻamau ke hōʻike ʻia i nā haʻahaʻa haʻahaʻa o ka tetrachloroethylene ma o ka lewa, ka meaʻai a me ka wai inu. He maikaʻi ka solubility o Tetrachloroethylene no nā hui inorganic a me nā mea ola he nui, e like me ka sulfur, iodine, mercuric chloride, aluminum chloride, momona, rubber a me ka resin, hoʻohana nui ʻia kēlā solubility ma ke ʻano he mea hoʻomaʻemaʻe metala degreasing, pena stripper agent, maloʻo hoʻomaʻemaʻe, rubber solvent, ink solvent, wai kopa, huluhulu kiʻekiʻe a me nā huluhulu degreasing; Hoʻohana pū ʻia ʻo Tetrachloroethylene ma ke ʻano he repellent (hookworm a me ka ginger worm); Mea hoʻopau no ka hana ʻana i nā lole.
1. Hoʻohana ʻia ma ke ʻano he mea hoʻoheheʻe organik, mea hoʻomaʻemaʻe maloʻo, mea hoʻokaʻawale aila, mea pale uahi, desulfurizer a me ka mea hoʻopau lole, a pēlā aku
2. Hoʻohana nui ʻia ʻo Tetrachloroethylene, hoʻohana nui ʻia ma ke ʻano he mea hoʻoheheʻe organik, mea hoʻomaʻemaʻe maloʻo, mea hoʻoheheʻe metala, a hoʻohana pū ʻia hoʻi e like me ka mea pale pepeke. Hiki ke hoʻohana ʻia ʻo Tetrachloroethylene ma ke ʻano he mea hoʻokaʻawale momona, mea kinai ahi a me ka mea pale uahi, a hiki ke hoʻohana ʻia e synthesize i nā trichloroethylene a me nā hui organik fluorinated.
3. Hoʻohana ʻia ma ke ʻano he mea hoʻoheheʻe organik, mea hoʻomaʻemaʻe maloʻo, desulfurizer a me ka mea hoʻopau lole
4. Hoʻohana nui ʻia ʻo Tetrachloroethylene, hoʻohana nui ʻia e like me ka mea hoʻoheheʻe organik, mea hoʻomaʻemaʻe maloʻo, mea hoʻoheheʻe metala degreasing, hoʻohana ʻia hoʻi e like me ka mea hoʻoheheʻe lāʻau lapaʻau enteroinsect repellent, mea maʻamau chromatographic analysis. Hiki ke hoʻohana ʻia ʻo Tetrachloroethylene e like me ka mea hoʻokaʻawale momona, mea kinai ahi a me ka mea pale uahi, a hiki ke hoʻohana ʻia e synthesize i nā trichloroethylene a me nā hui organik fluorinated.
