Mankhwala osungunula-methylene chloride wopangidwa ku China

Kuyambitsa Zoyambitsa

Wolemera mankhwala ndi wotsatsa wa China wa Kalasi ya Gichloromethane yopangidwa ku China, yomwe yakhala ikupanga mankhwala opangidwa ndi zaka 10. Kupereka zitsanzo zaulere, timalandira bwino kuti mugule make a Cas No. Mankhwala okhala ndi chiyero chachikulu komanso mtengo wotsika nafe.

Tsatanetsatane wazogulitsa
Ma molecular fomula: ch2cl2
Kulemera kwa maselo: 84.93
Mankhwala ndi mankhwala: Madzi opanda utoto amadzimadzi, ofanana ndi fungo la ether komanso lokoma.
Kachulukidwe kakang'ono: D4201.326kg / l.
malo owiritsa: 40.4 deg c.
Malo osungunuka: -96.7 madigiri, malo oyimitsa a 615 c. kusungunuka pang'ono m'madzi, kusungunuka mu ethanol, mphamvu ya ethyl ether, kukondoweza, kukondoweza. Dichlororthane ndi madzi a hydrolysis zomwe zimachitika, Dichloronorthane wokhala ndi malonda ogulitsa, kuteteza hydrolysis. Dichlororthane ndi okhazikika kwambiri oxygen imatulutsa osakaniza ophulika, koma osayaka, nthawi zambiri amagwiritsidwa ntchito popanga zoopsa, zopanda pake komanso zochepa zowira.

Cholinga
Kwa zosungunuka zopanda kanthu: kuyeretsa kwachitsulo, utoto chethetsani, kuwongolera chipembedzo, cellulose sentrate; filimu, aerosol, maantibayotiki ndi mavitamini popanga zosungunulira; wogwirizira wowononga chiwembu chopanga mapulasi; Zogulitsa zobwezera; ankakonda kusintha F11 ndi F12 kugwiritsidwa ntchito kwa kapangidwe ka zinthu; zinthu zabwino zamankhwala.

Kuyika, Kusunga ndi Kuyendetsa
Zitsulo zolimba, ng'oma yam'madzi yosindikizidwa kapena chidendene chosindikizidwa chodzaza ndi DEchloromethane, 80%, amatha kupereka chitetezo cha nayitrogeni kwa ogwiritsa ntchito. Kusunga kuyenera kusungidwa pamalo ozizira komanso ogulitsa ayenera kupumira ndi mpweya woipa kapena oxishones, kuti musalumikizidwe ndi madzi kuti mupewe hydrolysis. Kutumiza kudzatsatira ndi zopezeka kwa Republic of Fable za kunyamula mankhwala owopsa ndi misewu yayikulu ndi njanji.

Thanzi ndi Chitetezo

Sichlororthane mu gawo la mpweya wophulika: 8.1 ~ 17.2%, ndi ya mankhwala oyandikira. Kukhazikika kwakukulu, kuwonekera kwa nthawi yayitali kumayambitsa chizungulire, kugona, tinnitus kapena kukhazikika kwa mpweya, zomwe zimabwezeretsedwa mwachangu, sizingabweretse zinthu zosatha. Kuwaza m'maso kumayambitsa kupweteka komanso kukwiya, kucheza ndi khungu kumayambitsa dermatitis.
