Dimethyl carbonateUsage:
1. A new low toxic solvent inogona kutsiva toluene, xylene, ethyl acetate, butyl acetate, acetone kana butanone mumhizha yepende uye yekunamatira.Icho chigadzirwa chemakemikari chakasvibirira zvakatipoteredza
2. Yakanaka methylating agent, carbonylating agent, hydroxymethylating agent uye methoxylating agent inoshandiswa zvakanyanya kemikari mbishi zvinhu.
3. Phosgene, dimethyl sulfate, methyl chloroformate nemamwe makemikari ane muchetura anoonekwa seanotsiva.
4. Synthesis ye polycarbonate, diphenyl carbonate, isocyanate, nezvimwewo
5. Mukurapa, inoshandiswa kugadzira anti-infective zvinodhaka, antipyretic uye analgesic zvinodhaka, mavhitaminzi uye yepakati tsinga system zvinodhaka.
6. Mishonga yezvipembenene inonyanya kushandiswa kugadzira methyl isocyanate, uyezve mimwe mishonga yecarbamate nemishonga yezvipembenene (anisole)
7. Gasoline additives, lithium battery electrolyte, nezvimwewo

Hazardous Characteristics
Inopisa, inopisa kana moto wakazaruka uye kupisa kwakanyanya.Munzvimbo yemoto, midziyo inopisa ine njodzi yekuputika.
Zvigadzirwa zvinopisa zvinokuvadza
Carbon monoxide, carbon dioxide.
Nzira yekudzima moto
Jecha.Foam, hupfu hwakaoma, carbon dioxide.
Emergency treatment
Bvisa vashandi kubva munzvimbo yakasvibiswa uende kunzvimbo yakachengeteka nekukurumidza, vatsaure uye vadzivise kusvika kwavo.Bvisa tsime remoto.Zvinokurudzirwa kuti vashandi vekurapa kwekukurumidzira vapfeke-yega-yakanaka kudzvinyirira mweya uye zvipfeko zvebasa zve-anti-static.Usabata iyo leakage zvakananga.Cheka panobva kuvuza kusvika pazvinobvira.Dzivirira kuyerera munzvimbo dzakaganhurirwa dzakaita sepombi uye migero inorasa mvura.Kudonha kudiki: kunyura nejecha, vermiculite kana zvimwe zvinhu zvine inert.Unganidza uye utakure kunzvimbo yakashama kunovigwa, kufefeterwa kana kupiswa.Kudonha kukuru: kuvaka dike kana kuchera gomba rekuunganidza.Fukidza nefuro kuderedza njodzi yemhepo.Kuendesa kumota yetangi kana yakakosha muunganidzi ane pombi inoputika-isina kuputika, kudzokorodza kana kutakura kuenda kunzvimbo yekurasira tsvina kuti inoraswa.
Chengetedzo yekushanda
Kushanda kwemhepo uye kuwedzera kufefetera.Vashandi vanofanira kuwana kudzidziswa kwakakosha uye kunyatsotevedzera maitiro ekushanda.Zvinokurudzirwa kuti vashandisi vapfeke masiki egasi egasi (half masks), magirazi ekuchengetedza makemikari, zvipfeko zvebasa zveanti-static uye magurovhosi anodzivirira mafuta erabha.Ramba kure nemoto nekupisa.Kusvuta kunorambidzwa zvachose munzvimbo yebasa.Shandisa kuputika-proof ventilation system uye midziyo.Dzivirira kuti chiutsi chirege kupinda mumhepo yepabasa.Dzivisa kusangana neoxidants, reductants uye acids.Bata nehanya kudzivirira kukanganisa pasuru uye mudziyo.Midziyo yekudzimisa moto uye midziyo yekudzimisa yekukurumidzira yemhando dzinoenderana uye huwandu huchapihwa.Mudziyo wakaputswa unogona kunge uine zvinhu zvinokuvadza.
Kuchengetedza kuchengetedza
Chengeta muimba inotonhorera, yakaoma uye ine mhepo yakanaka isingabatiki.Ramba kure nemoto nekupisa.Tembiricha yekuchengetera haifanirwe kudarika 10 ℃.Chengeta midziyo yakavharwa.Ichachengetwa zvakasiyana kubva kune oxidants, reductants, acids, nezvimwewo uye yakasanganiswa yekuchengetedza haibvumirwi.Kuputika kwemwenje wemwenje uye mhepo yekufefetera ichagamuchirwa.Zvinorambidzwa kushandisa michina michina uye maturusi ari nyore kugadzira sparks.Nzvimbo yekuchengetera ichave yakashongedzerwa neyakavuza yekurapa yekukurumidzira michina uye yakakodzera yekugamuchira zvinhu.
