Diethyl Carbonate Darajada Warshadaha DEC

Diethyl carbonate waa dareere aan midab lahayn oo hufan oo leh cabbirrada jireed ee soo socda: cufnaanta 0.975 garaam halkii senti mitir cubic, barta dhalaalaysa -43 ℃, barta karkarinta 126 - 128 ℃, dhibicda 25 ℃ (koob xiran), index refractive 1.384 at 20.1 kilomitir vaposrated. 20 ℃, cadaadiska muhiimka ah 3.39 megapascals, dhibic shiida 445 ℃. Xadka qarxa waa 1.4% - 11.0% (mugga/mugga). Walaxdani kuma milmi karto biyaha, laakiin waxa ay noqon kartaa mid la isku khaldo inta badan dareerayaasha organic (sida alkolada, ketones, esters, iyo hydrocarbons caraf udgoon).

Carbonate Diethyl waxaa inta badan loo isticmaalaa isku-dhafka dabiiciga ah iyo isku-darka daroogada. Waxa kale oo loo isticmaali karaa sida dareere loogu talagalay resins, saliidaha, nitrocellulose iyo ethers cellulose, oo waxay ku dabaqi kartaa xaaladaha warshadaha kala duwan.

Codsiyada ugu muhiimsan ee kaarboonaytka diethyl waxaa ka mid ah in loo isticmaalo sidii qayb elektrolyte ah oo ku jirta baytariyada lithium, dhex dhexaad u ah isku dhafka dabiiciga ah, dhexdhexaadinta isku dhafka daroogada, iyo sida dareere loogu talagalay resins, saliidaha, nitrocellulose iyo ethers cellulose.

Meelaha codsiga gaarka ah waa sida soo socota

Codsiga warshadaha batteriga:

Waxaa inta badan loo isticmaalaa si warshado ahaan ah sida elektrolytka loogu talagalay baytariyada lithium-ion ee dib loo dallaci karo waxaana lagu shaqeyn karaa oo kaliya jawi qalalan (sida sanduuqa galoofyada oo leh wax ka yar 20 ppm ee qoyaanka deegaanka).

Codsiga isku dhafka dabiiciga ah:

1. Sida diethyl carbonate, waa reagent kaarboonylation ah oo caadi ahaan loo isticmaalo, kaas oo loo isticmaali karo in lagu farsameeyo ketones, alkolada sare iyo xeryahooda heterocyclic.

2. Waxaa inta badan loo isticmaalaa carbonylation of enol negative ions, oo leh xaalado falcelin khafiif ah iyo dhalidda sare.

3. Waxa loo isticmaali karaa sidii silicate karboonayt ah iyo reagent alkylation substrates nucleophilic.

Codsiga daawada iyo sunta cayayaanka:

1. Warshadaha dawooyinka, waxa loo isticmaalaa in lagu soo saaro dawooyinka sida phenobarbital iyo erythromycin.

2. Warshadaha cayayaanka, waxaa loo isticmaalaa in lagu soo saaro sunta cayayaanka sida pyrethroids.

Codsiga dareeraha warshadaha:

1. Wax soo saarka kiimikaad, waxaa loo isticmaalaa sida dareeraha nitrocellulose, ethers cellulose, resins synthetic iyo resins dabiiciga ah.

2. In daabacaadda dharka iyo dheehidda, waxay ka dhigi kartaa qaybinta dheeha lebbiska, hagaajinta waxqabadka qorraxda iyo hagaajinta dareenka dharka.

Codsiyada kale:

1. Warshadaha qalabka, waxaa loo isticmaalaa in lagu soo saaro qalabka wax lagu dhejiyo, kuwaas oo loo isticmaalo xirmooyinka dhejiska ee cathodes ee tuubooyinka elektiroonigga ah.

2. Kiimikada falanqaynta, waxa loo istcimaalaa sidii reagen kiimiko ahaan.

Shuruudaha kaydinta

Kaarboonaytka Diethyl waa in lagu kaydiyaa bakhaar qabow, qalalan oo hawo leh, kana fog ilaha dabka iyo meelaha kulaylka. Heerkulka bakhaarku waa inuusan dhaafin 37 ℃. Weelka waa in la xidhaa oo waa in lagu kaydiyaa si gooni ah oo ka soocan oksaydhiyeyaasha, reductants, acids, iyo kiimikooyinka cuntada. Ka fogow kaydinta isku dhafan oo isticmaal nalalka aan qarxin iyo tas-hiilaadka hawo-siinta.

Kiimikadayada sida aadka ah loo iibiyo waxaa ka mid ah dareerayaasha warshadaha iyo dhexdhexaadiyeyaasha kiimikaad, sida Taxanaha Alcohol, Taxanaha Ether, Esters, Precursor Series, Acid-Ester Solvents, Bacrimiyeyaasha NPK-Biyaha-Milan, iyo Kiimikada kale ee Warshadaha. Alaabooyinkani waxay ka kooban yihiin sahay deggan, nadiifnimo la isku halayn karo, iyo heerar tayo leh oo joogto ah. Weydiinta waa la soo dhawaynayaa.
