I-Chemical Solvents-Methylene Chloride Yenziwe eChina

Isingeniso Somkhiqizo

I-Rich Chemical ingumphakeli wase-China ochwepheshile we-dichloromethane yezinga lezimboni eyenziwe e-china, osekuyiminyaka eyi-10 yenza amakhemikhali emvelo. Ukunikeza isampula yamahhala, sikwamukela ngemfudumalo ukuthi uthenge amakhemikhali ekhwalithi ephezulu ye-CAS No. anokuhlanzeka okuphezulu kanye nenani eliphansi nathi.

Imininingwane yomkhiqizo
Ifomula yemolekyuli: CH2CL2
Isisindo se-molecule: 84.93
Izakhiwo zomzimba namakhemikhali:uketshezi oluguquguqukayo olungenambala olungenambala, olufana nephunga le-ether nelimnandi.
Ukuminyana okuhlobene: D4201.326Kg/L.
indawo abilayo: 40.4 DEG C.
indawo encibilikayo: -96.7 degrees, indawo yokuthungela engu-615 DEG C. Incibilika kancane emanzini, inyibilika ku-ethanol, i-ethyl ether, i-toxic, i-narcotic stimulation. I-Dichloromethane ne-water hydrolysis reaction, i-dichloromethane equkethe i-commercial stabilizer, ukuvimbela i-hydrolysis. I-Dichloromethane ne-high concentration oxygen izokhiqiza ingxube eqhumayo, kodwa engashi, ivame ukusetshenziswa embonini yobuthi obuphansi, i-solvent engashi nendawo yokubilisa ephansi.

Inhloso
I-solvent engashi: ukuhlanzwa kwensimbi, isikhiphi sikapende, i-ejenti yokwehlisa insimbi, i-solvent ye-cellulose acetate emithathu; ifilimu, i-aerosol, ama-antibiotics namavithamini ekukhiqizeni i-solvent; i-ejenti ekhihliza amagwebu yokukhiqiza amapulasitiki obunjiniyela; imikhiqizo ye-flame retardant; esetshenziselwa ukufaka esikhundleni se-F11 ne-F12 ekuhlanganiseni kwemikhiqizo; imikhiqizo emihle yamakhemikhali.

Ukupakisha, ukugcinwa kanye nezokuthutha
Insimbi ebilisiwe, isigubhu sensimbi esimnyama noma ithangi elivalwe uphawu lokugcwalisa umthamo we-dichloromethane, i-80%, linganikeza ukuvikelwa kwe-nitrogen kubasebenzisi abanezidingo ezikhethekile. Isitoreji kufanele sigcinwe endaweni epholile futhi eyomile, indawo yokugcina impahla kufanele ingene umoya ukuze igweme ukuthintana ne-oksijeni ephezulu noma ama-oxides, ukugwema ukuthintana namanzi ukuze kuvinjelwe i-hydrolysis. Izinto zokuthutha zizothobelana nezinhlinzeko ze-People's Republic of China mayelana nokuthuthwa kwamakhemikhali ayingozi ngemigwaqo emikhulu nojantshi.

Impilo nokuphepha

I-Sichloromethane emkhawulweni wokuqhuma komoya: 8.1 ~ 17.2%, ingeyamakhemikhali avuthayo. Ukugxila okuphezulu, ukuchayeka isikhathi eside kubangela kalula isiyezi, ukozela, isicanucanu, i-tinnitus noma ukuba ndikindiki kwamalungu, ukuya emoyeni omusha, izimpawu zibuyiselwa ngokushesha, ngeke zidale umonakalo ohlala njalo. Ukuqhuma emehlweni kubangela ubuhlungu nokucasuka, ukuthintana isikhathi eside nesikhumba kungabangela i-dermatitis.
