Utu Pai a te Kaihanga PERCHLOROETHYLENE CAS: 127-18-4

whakaahuatanga poto:

PERCHLOROETHYLENE: e mōhiotia ana hoki ko te chloride katoa. Mō te hanganga ngota, i whakakapia ngā matū i hangaia e ngā ngota hauwai katoa i roto i te ethylene ki te chlorine. I te tau 1821, ko te wā tuatahi tēnei i hangaia ai mā te whakamahana wera o FaraDay. He wai mārama, kāore he tae. He kakara rite ki te ether. Kāore e mura.

Whakaahuatanga

Papatipu ngota whanaunga 165.85. Kiato whanaunga 1.6220. Ko te ira rewa -22.7 ℃. Ko te ira kohua 121.2 ℃, 33.2 ℃ (4.000 × 103Pa). Ko te taupū whakaata ko 1.5055. Ko te matotoru ko 0.839MPA · s (20 ° C). Pēhanga kohu (× 103Pa): 5.466 (40 ° C), 13.865 (60 ° C), 30.131 (80 ° C), 58.128 (100 ° C). Kāore te Tetthylene e wairewa i roto i te huka, te glycerin me te pūmua, ā, he paku wairewa ki te wai (0.015 ina 25 ° C), ka taea te wairewa ki te etanoru, te etera, te chloroform, te benzene, me ngā whakarewa waro chlorine. Kāore e waikura. Kei te pumau tonu a CHEMICALBOOK i te 500 °C i raro i te aroaro o te hau kore, te makuku me te kore he whakakorikori. Ka taea te whakaputa i te Tethelhyloethane i te wā o te hauwai. Ka puta te Tiroroethane i te wā o te hauota. Ka taea hoki e te Tetrachloride te tauhohe ki te bromine hei whakaputa i te bromine moana chlorine, i te diptide chloride rānei. I raro i te mahi a te whakakorikori, ka taea hoki e ia te tauhohe ki te hauwai fluoride. I raro i te noho o te mārama, te hau, me te wai mō te wā roa, ka pōturi te pirau ki te trichloride me te mārama, ko ngā konganuku waikura pēnei i te rino, te konumohe, me te konutea ka taea te pehi ki ngā whakau. Mena he waro whakahohe, ka whakamahanahia ki te 700 °C kia pirau ki te hex chloride me te hex chloroline. Ka taea te waikura i te Tethalothene e te waikura kaha. Ka taea e te Tetthyl chloride te whai tauhohe matū kino ki te paura māwhero, māwhero, te lithium dandruff, te tetraoxide, me te konutai hauwai. He paitini te Tetrachloride, ā, he aukati io pokapū, ka taea te mamae o te upoko, te whakapairuaki, te ruaki, tae noa ki te koma. Ko te kiore he LD508850mg/kg. Ko te rahinga mōrahi e whakaaetia ana mō te wāhi mahi he 100 × 10-6.

Ngā Whakamahinga o te PERCHLOROETHYLENE

I roto i te ahumahi, ko te PERCHLOROETHYLENE te nuinga e whakamahia ana hei whakarewa, hei hanga rauropi, hei horoi mata whakarewa me te kaihoko horoi maroke, hei tango i te whanariki, hei reo whakawhiti wera. E whakamahia ana i roto i te rongoā hei rongoā anthelmintic. He takawaenga hoki o te trichloroethylene me ngā mea rauropi fluorinated. Tērā pea ka pāngia te hunga noho whānui e te iti o te kukū o te tetrachloroethylene mā te hau, te kai me te wai inu. He pai te wairewatanga o te Tetrachloroethylene mō te maha o ngā matū kore-rauropi me ngā matū rauropi, pērā i te whanariki, te iodine, te mercuric chloride, te konumohe chloride, te ngako, te rapa me te kapia, ā, he whānuitia te whakamahinga o taua wairewatanga hei kaihoko horoi tango hinu whakarewa, hei kaihoko tango peita, hei kaihoko horoi maroke, hei whakarewa rapa, hei whakarewa waituhi, hei hopi wai, hei tango hinu huruhuru me ngā huruhuru kounga teitei; E whakamahia ana hoki te Tetrachloroethylene hei ārai (kutukutu matau me te kutukutu kanekane); hei kaihoko whakaoti mō te tukatuka kakahu.
1. Whakamahia hei whakarewa waro, hei horoi maroke, hei tango hinu, hei mata paowa, hei tango whanariki me te whakaoti kakahu, me ētahi atu
2. He whānuitia te whakamahinga o te Tetrachloroethylene, ko te nuinga hei whakarewa waro, hei horoi maroke, hei whakarewa tango hinu whakarewa, ā, hei ārai pepeke hoki. Ka taea te whakamahi i te Tetrachloroethylene hei tango ngako, hei tinei ahi, hei ārai paowa, ā, ka taea hoki te whakamahi hei hanga i te trichloroethylene me ngā matū waro kua whakapūhaumāotahia.
3. Whakamahia hei whakarewa waro, hei horoi maroke, hei tango pūhā me te whakaoti kakahu
4. He whānuitia te whakamahinga o te Tetrachloroethylene, te nuinga hei whakarewa waro, hei horoi maroke, hei whakarewa tango hinu whakarewa, hei whakarewa rongoā ārai pepeke, hei rauemi paerewa tātari chromatography. Ka taea te whakamahi i te Tetrachloroethylene hei tango ngako, hei tinei ahi me te ārai paowa, ā, ka taea hoki te whakamahi hei hanga i te trichloroethylene me ngā matū waro fluorinated.
5. He whakarewa e whakamahia ana hei ngako, hei matū rite-ngako rānei i roto i te tātaritanga rauropi. He matū matū chromatography wai pēhanga teitei. He whakarewa mō te whakatau irahiko. He hanga rauropi.
