Chemical Solvents-Methylene Chloride Yopangidwa ku China

Chiyambi cha Zamalonda

Rich Chemical ndi katswiri waku China wogulitsa dichloromethane wamafakitale wopangidwa ku China, yemwe wakhala akupanga mankhwala achilengedwe kwa zaka 10. Kupereka chitsanzo chaulere, tikukulandirani mwachikondi kuti mugule mankhwala apamwamba a CAS No.

Zambiri zamalonda
Fomula ya maselo: CH2CL2
Kulemera kwa molekyulu: 84.93
Thupi ndi mankhwala katundu: colorless mandala kosakhazikika madzi, ofanana ndi fungo la ether ndi okoma.
Kachulukidwe wachibale: D4201.326Kg/L.
kutentha kwapakati: 40.4 DEG C.
malo osungunuka: -96.7 madigiri, poyatsira 615 DEG C. Kusungunuka pang'ono m'madzi, kusungunuka mu ethanol, ethyl ether, poizoni, kukondoweza kwa mankhwala osokoneza bongo. Dichloromethane ndi madzi hydrolysis reaction, dichloromethane munali malonda stabilizer, kuteteza hydrolysis. Dichloromethane ndi mpweya wambiri wa okosijeni umatulutsa kusakaniza kophulika, koma kosayaka, komwe kumagwiritsidwa ntchito m'makampani omwe ali ndi kawopsedwe kakang'ono, zosungunulira zosayaka komanso malo otentha otsika.

Cholinga
Zosungunulira zosayaka: kuyeretsa zitsulo, chochotsera utoto, chosungunulira zitsulo, zosungunulira zitatu za cellulose acetate; filimu, aerosol, maantibayotiki ndi mavitamini pakupanga zosungunulira; chopangira thovu popanga mapulasitiki aumisiri; zinthu zoletsa moto; amagwiritsidwa ntchito m'malo mwa F11 ndi F12 ntchito popanga zinthu; mankhwala abwino.

Kuyika, kusunga ndi zoyendera
Chitsulo chagalasi, ng'oma yachitsulo yakuda kapena thanki yosindikizidwa yodzaza chidebe chodzaza dichloromethane, 80%, imatha kupereka chitetezo cha nayitrogeni kwa ogwiritsa ntchito omwe ali ndi zofunikira zapadera. Zosungirako ziyenera kusungidwa pamalo ozizira ndi owuma, nyumba yosungiramo katunduyo iyenera kukhala ndi mpweya wokwanira kuti musagwirizane ndi mpweya wambiri wa okosijeni kapena ma oxides, kupewa kukhudzana ndi madzi kuti muteteze hydrolysis. Zonyamula zikuyenera kutsatira zomwe dziko la People's Republic of China likufuna zotengera kunyamula mankhwala oopsa kudzera m'misewu yayikulu ndi njanji.

Thanzi ndi chitetezo

Sichloromethane mu malire a kuphulika kwa mpweya: 8.1 ~ 17.2%, ndi ya mankhwala oyaka. Kukhazikika kwakukulu, kuwonetseredwa kwa nthawi yayitali kumayambitsa chizungulire, kugona, nseru, tinnitus kapena dzanzi la miyendo, kusunthira kumpweya wabwino, kubwezeretsedwanso kwazizindikiro, sikungayambitse kuwonongeka kosatha. Kuwombera m'maso kumayambitsa kupweteka ndi kukwiya, kukhudzana kwa nthawi yaitali ndi khungu kungayambitse dermatitis.
