Dimethyl carbonateUkusetyenziswa:
1. I-solvent entsha ephantsi enetyhefu ingathatha indawo ye-toluene, i-xylene, i-ethyl acetate, i-butyl acetate, i-acetone okanye i-butanone kwishishini lepeyinti kunye ne-adhesive.Yimveliso yeekhemikhali eziluhlaza ezihambelana nokusingqongileyo
2. I-agent ye-methylating elungileyo, i-carbonylating agent, i-hydroxymethylating agent kunye ne-methoxylating agent zisetyenziswa ngokubanzi imathiriyeli ekrwada yeekhemikhali.
3. I-Phosgene, i-dimethyl sulfate, i-methyl chloroformate kunye nezinye iikhemikhali ezinetyhefu kakhulu zithathwa njengeendawo ezithatha indawo.
4. I-synthesis ye-polycarbonate, i-diphenyl carbonate, i-isocyanate, njl
5. Kwezamayeza, isetyenziselwa ukwenza amayeza e-anti-infective, i-antipyretic kunye ne-analgesic drugs, iivithamini kunye namachiza e-central nervous system.
6. I-Pesticides isetyenziselwa ukuvelisa i-methyl isocyanate, kunye neziyobisi ze-carbamate kunye nezibulali-zinambuzane (i-anisole)
7. Izongezo zepetroli, i-lithium battery electrolyte, njl
Dimethyl carbonateulwazi lwezothutho:

Iimpawu ezinobungozi
Ukutsha, ukutsha kwimeko yomlilo ovulekileyo kunye nobushushu obuphezulu.Kwindawo yomlilo, izikhongozeli ezishushu zinomngcipheko wokudubula.
Iimveliso zokutsha ezinobungozi
Ikharbhon monoxide, ikharbon diokside.
Indlela yokucima umlilo
Isanti.Igwebu, umgubo owomileyo, ikharbon diokside.
Unyango olungxamisekileyo
Bakhuphe abasebenzi kwindawo evuzayo ubase kwindawo ekhuselekileyo ngokukhawuleza, babeke bodwa kwaye uthintele ngokungqongqo ukufikelela kwabo.Sika umthombo womlilo.Kucetyiswa ukuba abasebenzi bonyango olungxamisekileyo banxibe izixhobo zokuphefumla zoxinzelelo ezizimeleyo kunye nempahla yokusebenza echasene ne-static.Musa ukubamba ukuvuza ngokuthe ngqo.Sika umthombo wokuvuza kangangoko.Thintela ekungeneni kwiindawo ezithintelweyo ezifana nemijelo ephantsi komhlaba ehambisa amanzi amdaka kunye nemisele yokukhupha izandyondyo.Ukuvuza okuncinci: ukufunxa ngesanti, i-vermiculite okanye ezinye izinto ezingenayo.Ukuqokelela uze uthuthelwe kwindawo evulekileyo ukuze kungcwatywe, kube ngumphunga okanye ukutshiswa.Ukuvuza okukhulu: Yakha idike okanye umbe umngxuma ukuze uqokelelwe.Gquma ngegwebu ukunciphisa intlekele yomphunga.Ukutshintshela kwimoto yetanki okanye umqokeleli okhethekileyo ngempompo engagqabhukiyo, isetyenziswe ngokutsha okanye ithuthelwe kwindawo yokucoca inkunkuma ukuze ilahlwe.
Imiqathango yokusebenza
Ukusebenza okungangeni moya kunye nokuphucula umoya.Abanini-zithuthi kufuneka bafumane uqeqesho olulodwa kwaye bathobele ngokungqongqo iinkqubo zokusebenza.Kucetyiswa ukuba abaqhubi banxibe iimaski zegesi yokucoca i-self-priming (i-half masks), iiglasi zokhuseleko lwekhemikhali, iimpahla ezichasene ne-static kunye neeglavu ezixhathisa i-oyile yerabha.Zigcine kude nomlilo kunye nemithombo yobushushu.Ukutshaya akuvumelekanga ngokungqongqo emsebenzini.Sebenzisa isixokelelwano sokungenisa umoya esingagqabhukiyo kunye nezixhobo.Thintela umphunga ekubeni ungavuzi emoyeni wasemsebenzini.Kuphephe ukudibana ne-oxidants, i-reductants kunye ne-asidi.Phatha ngononophelo ukukhusela umonakalo kwiphakheji kunye nesitya.Izixhobo zokucima umlilo kunye nokuvuza kwezixhobo zonyango olungxamisekileyo kwiindidi ezihambelanayo kunye nobungakanani ziya kubonelelwa.Izikhongozeli ezikhutshiweyo zisenokuba nezinto eziyingozi.
Izilumkiso zokugcina
Gcina kwindawo epholileyo, eyomileyo nengena moya kakuhle engatshiyo.Zigcine kude nomlilo kunye nobushushu.Ubushushu bokugcina akufunekanga budlule kwi-10 ℃.Gcina izikhongozeli zivaliwe.Iya kugcinwa ngokwahlukileyo kwi-oxidants, i-reductants, i-acids, njl. kunye nokugcinwa okuxutywe akuyi kuvunyelwa.Izibane ezikhusela uqhushumbo kunye neendawo zokungenisa umoya ziya kwamkelwa.Akuvumelekanga ukusebenzisa izixhobo zoomatshini kunye nezixhobo ezilula ukuvelisa iintlantsi.Indawo yokugcina iya kuxhotyiswa ngezixhobo zonyango olungxamisekileyo oluvuzayo kunye nezixhobo ezifanelekileyo zokufumana.
