Dimethyl kaboneti CAS 616-38-6
Kaboneti Dimethyl, ti a tọka si bi DMC, jẹ omi ti ko ni awọ, ti o han gbangba pẹlu õrùn õrùn ni iwọn otutu yara. Idiwọn ojulumo rẹ (d204) jẹ 1.0694, aaye yo jẹ 4°C, aaye didan rẹ jẹ 90.3°C, aaye filasi rẹ jẹ 21.7°C (ṣii) ati 16.7°C (ni pipade), atọka itọka rẹ (nd20) jẹ 1.3687, ati pe kii ṣe majele. O le wa ni idapo pelu fere gbogbo Organic olomi bi alcohols, ketones, ati esters ni eyikeyi o yẹ ati ki o jẹ die-die tiotuka ninu omi. O le ṣee lo bi oluranlowo methylating. Ti a ṣe afiwe pẹlu awọn aṣoju methylating miiran, gẹgẹbi methyl iodide ati dimethyl sulfate, dimethyl carbonate ko kere si majele ti o le jẹ biodegraded.

Dimethyl carbonate (DMC) ni eto molikula alailẹgbẹ (CH3O-CO-OCH3). Ilana molikula rẹ ni carbonyl, methyl, methoxy ati awọn ẹgbẹ carbonylmethoxy ninu. Nitorinaa, o le jẹ lilo pupọ ni awọn aati iṣelọpọ Organic gẹgẹbi carbonylation, methylation, methoxylation ati carbonylmethylation. O ni iwọn lilo pupọ pupọ. O jẹ lilo ni akọkọ bi carbonylation ati reagent methylation, aropo petirolu, ati ohun elo aise fun iṣelọpọ polycarbonate (PC). Iṣelọpọ titobi nla ti DMC ti ni idagbasoke pẹlu ilana iṣelọpọ ti kii-phosgene ti polycarbonate. Awọn lilo rẹ jẹ bi wọnyi:
1. Iru tuntun ti epo kekere-kekere le rọpo awọn ohun elo bi toluene, xylene, ethyl acetate, butyl acetate, acetone tabi butanone ninu awọ ati awọn ile-iṣẹ alamọpọ. O jẹ ọja kemikali alawọ ewe ti o ni ibatan ayika.
2. Aṣoju methylating ti o dara, oluranlowo carbonylating, oluranlowo hydroxymethylating ati oluranlowo methoxylating. O ti wa ni o gbajumo ni lilo ninu awọn aaye ti ounje antioxidants, ọgbin Idaabobo òjíṣẹ, bbl O jẹ kan ni opolopo lo kemikali aise ohun elo.
3. Apopo ti o dara julọ fun awọn oogun majele ti o ga julọ gẹgẹbi phosgene, dimethyl sulfate, ati methyl chloroformate.
4. Synthesize polycarbonate, diphenyl carbonate, isocyanate, bbl
5. Ni oogun, o ti wa ni lo lati synthesize egboogi-arun oloro, antipyretic ati analgesic oloro, vitamin oloro, ati oloro fun awọn aringbungbun aifọkanbalẹ eto.
6. Ni awọn ipakokoropaeku, o jẹ pataki julọ lati ṣe iṣelọpọ methyl isocyanate, ati lẹhinna lati ṣe awọn oogun carbamate kan ati awọn ipakokoro (anisole).
7. Awọn afikun petirolu, awọn elekitiroti batiri litiumu, ati bẹbẹ lọ.
