Izityholo zekhemikhali-i-phethylene chloride eyenziwe eTshayina

Intshayelelo Intshayelelo

Imichiza etyebileyo inguMthengisi wase-chine onobuchule weBanga lezoMveliso yeBanga lezemizi-mveliso eyenziwe eTshayina, ebibandakanyeke kwiikhemikhali ze-organic iminyaka eli-10. Ukuhambisa isampulu yasimahla, sikwamkela ngokufudumeleyo ukuba uthenge i-CAS ephezulu esemgangathweni. Imichiza enobunyulu obuphezulu kunye nexabiso eliphantsi nathi.

Iinkcukacha zemveliso
Ifomula yemolekyula: Ch2cl2
Ubunzima bemolekyuli: 84.93
Ipropathi yomzimba kunye neekhemikhali: Ulwelo olungenamibalabala lwe-prootile, olufanayo kwiphunga le-ether kwaye limnandi.
Ukuxinana kwesihlobo: D4201.3226KG / L.
Inqaku lokubila: 40.4 Deg c.
Inqaku lokunyibilika: I-Dichloromethane kunye ne-Hydrolysis yokuphendula, iDichloromethane iqulathe i-stabilizer yentengiso, ukuthintela i-hydrolysis. I-Dichloromethane kunye neoksijini ephezulu iya kuvelisa umxube wokuqhuma, kodwa isetyenziswa ngokutsha, isetyenziswa kwimizi-mveliso yetyhefu yetyhefu yetyhefu, engafakwanga kunye nendawo yokubila ephantsi.

Injongo
Ngesolvent engafunekiyo: Ukucoca intsimbi, ipeyinti yepeyinti, i-piepreds, isinyithi esithathu se-seluplose ye-selcetate isombo; ifilimu, i-aerosol, i-antibiotics kunye neevithamini kwimveliso yesolutywa; iarhente yokugweba yokuveliswa kwemveliso yobunjineli; iimveliso ezihlawulelweyo; isetyenziselwa ukutshintsha i-F11 kunye ne-F12 ye-synthesis yemveliso; Iimveliso ezintle zekhemikhali.

Ukupakisha, ukugcinwa kunye nokuhamba
Intsimbi ye-galvanited, isigubhu sentsimbi emnyama okanye itanki yokutsala itayitile yokugcwalisa ivolumu yedigrimethane, i-80%, inokubonelela ngokhuseleko lwe-witrogen kubasebenzisi abaneemfuno ezizodwa. Ukugcinwa kufuneka kugcinwe kwindawo epholileyo neyomileyo, indawo yokugcina izinto kufuneka iphumelele ukunqanda ukunxibelelana neoksijini okanye i-oxidal, ukuthintela ukunxibelelana namanzi ukuze kuthintelwe i-hydrolysis. Uthutho luya kuthobela izibonelelo zeRiphabliki yase China malunga nothutho lweekhemikhali eziyingozi kwiindlela eziphezulu kunye neendlela zololiwe.

Impilo nokhuseleko

I-Sichloromethane kumda wokuqhushumba womoya: 8.1 ~ 17.2%, yeyakwimichiza enokutsha. Uxinzelelo oluphezulu, ukuvezwa kwexesha elide kubangela isikizi, ukunxila, isicaphucaphu, i-tinnitus okanye ukungcungcutheka kwamalungu, kuya kukhawuleza iimpawu, akuyi kuvuyela ukonakala okungapheliyo. I-Splash emehlweni ibangela ukuba iintlungu kunye nokucaphuka, ukunxibelelana kwexesha elide kunye nolusu kunokubangela i-dermatitis.
