Izinyibilikisi Zamakhemikhali–I-Methylene Chloride Eyenziwe eShayina

Isingeniso Somkhiqizo

I-Rich Chemical ingumhlinzeki ochwepheshe waseShayina we-dichloromethane yezinga lezimboni eyenziwe eShayina, ebilokhu isetshenziswa kumakhemikhali e-organic iminyaka eyi-10. Njengoba inikeza isampula yamahhala, sikwamukela ngemfudumalo ukuthi uthenge amakhemikhali e-CAS No. asezingeni eliphezulu ahlanzekile kakhulu futhi anentengo ephansi nathi.

Imininingwane yomkhiqizo
Ifomula yama-molecule: CH2CL2
Isisindo sama-molecule: 84.93
Izakhiwo zomzimba nezamakhemikhali: uketshezi oluguquguqukayo olungenambala, olufana nephunga le-ether nelimnandi.
Ubuningi obuhlobene: D4201.326Kg/L.
iphuzu lokubilisa: 40.4 DEG C.
iphuzu lokuncibilika: -96.7 degrees, iphuzu lokuvutha elingu-615 DEG C. Lincibilika kancane emanzini, lincibilika ku-ethanol, i-ethyl ether, livuselela ubuthi, futhi lidala i-narcotic. I-Dichloromethane kanye ne-hydrolysis reaction yamanzi, i-dichloromethane equkethe i-commercial stabilizer, ukuvimbela i-hydrolysis. I-Dichloromethane kanye ne-oxygen ephezulu kuzokhiqiza ingxube eqhumayo, kodwa hhayi evuthayo, ivame ukusetshenziswa embonini yobuthi obuphansi, i-solvent engashi kanye nephuzu eliphansi lokubila.

Inhloso
Kwe-solvent engashi: ukuhlanza insimbi, ukususa upende, i-ejenti yokususa amafutha ensimbi, i-solvent ye-cellulose acetate emithathu; ifilimu, i-aerosol, ama-antibiotic namavithamini ekukhiqizweni kwe-solvent; i-ejenti ye-foam yokukhiqiza amapulasitiki obunjiniyela; imikhiqizo evimbela ilangabi; esetshenziselwa ukufaka esikhundleni se-F11 ne-F12 ekuhlanganiseni imikhiqizo; imikhiqizo yamakhemikhali amancane.

Ukupakishwa, ukugcinwa kanye nokuthuthwa
Insimbi egayiwe, isigubhu sensimbi emnyama noma isitsha sokupakisha esivalwe ngethangi, ivolumu yokugcwalisa ye-dichloromethane, engu-80%, ingahlinzeka ngokuvikelwa kwe-nitrogen kubasebenzisi abanezidingo ezikhethekile. Indawo yokugcina kufanele igcinwe endaweni epholile neyomile, isitoreji kufanele singene umoya ukuze kugwenywe ukuthintana nokushisa okuphezulu kwe-oxygen noma ama-oxide, ukuze kugwenywe ukuthintana namanzi ukuze kuvinjelwe i-hydrolysis. Ezokuthutha kufanele zihambisane nezinhlinzeko zeRiphabhulikhi Yabantu baseShayina mayelana nokuthuthwa kwamakhemikhali ayingozi ngemigwaqo emikhulu kanye nezitimela.

Impilo nokuphepha

Umkhawulo wokuqhuma komoya we-Sichloromethane: 8.1 ~ 17.2%, ungowamakhemikhali avuthayo. Ukuhlushwa okuphezulu, ukuchayeka isikhathi eside kubangela kalula isiyezi, ukozela, isicanucanu, i-tinnitus noma ukungabi namandla kwamalungu, kuya emoyeni omusha, izimpawu zibuyiselwa ngokushesha, ngeke zibangele umonakalo ohlala njalo. Ukuchayeka emehlweni kubangela ubuhlungu nokucasuka, ukuthintana isikhathi eside nesikhumba kungabangela i-dermatitis.
