Yintoni iDimethyl carbonate CAS 616-38-6?

I-Dimethyl carbonate, ebizwa ngokuba yi-DMC, lulwelo olungenambala, olucacileyo olunevumba elibi kubushushu begumbi. Uxinano lwayo (d204) yi-1.0694, iqondo layo lokunyibilika yi-4°C, iqondo layo lokubila yi-90.3°C, iqondo layo lokutsha yi-21.7°C (livuliwe) kunye ne-16.7°C (livaliwe), i-refractive index yayo (nd20) yi-1.3687, kwaye iyatsha kwaye ayinatyhefu. Ingaxutywa phantse nazo zonke izinyibilikisi ze-organic ezifana nee-alcohols, ii-ketones, kunye nee-esters nangayiphi na indlela kwaye iyanyibilika kancinci emanzini. Ingasetyenziswa njenge-methylating agent. Xa ithelekiswa nezinye ii-methylating agents, ezifana ne-methyl iodide kunye ne-dimethyl sulfate, i-dimethyl carbonate ayinabungozi kangako kwaye inokubola.

Isicelo

I-Dimethyl carbonate (DMC) inesakhiwo semolekyuli esahlukileyo (CH3O-CO-OCH3). Isakhiwo sayo semolekyuli siqulathe amaqela e-carbonyl, methyl, methoxy kunye ne-carbonylmethoxy. Ke ngoko, ingasetyenziswa kakhulu kwiimpendulo ze-organic synthesis ezifana ne-carbonylation, i-methylation, i-methoxylation kunye ne-carbonylmethylation. Inoluhlu olubanzi kakhulu lokusetyenziswa. Isetyenziswa kakhulu njenge-carbonylation kunye ne-methylation reagent, isongezo sepetroli, kunye nezinto eziluhlaza zokwenza i-polycarbonate (PC). Imveliso enkulu ye-DMC iphuhlisiwe kunye nenkqubo yokwenziwa kwe-polycarbonate engeyiyo i-phosgene. Ukusetyenziswa kwayo kulandelayo:

1. Uhlobo olutsha lwesinyibilikisi esingenatyhefu ingathabatha indawo yezinyibilikisi ezifana ne-toluene, i-xylene, i-ethyl acetate, i-butyl acetate, i-acetone okanye i-butanone kumashishini epeyinti kunye ne-adhesive. Yimveliso yekhemikhali eluhlaza enobuhlobo nokusingqongileyo.

2. I-arhente elungileyo ye-methylating, i-arhente ye-carbonylating, i-arhente ye-hydroxymethylating kunye ne-arhente ye-methoxylating. Isetyenziswa kakhulu kwicandelo le-antioxidants yokutya, ii-arhente zokukhusela izityalo, njl. Yinto esetyenziswa kakhulu kwi-chemical green material.

3. Indawo efanelekileyo yokuthatha indawo yeziyobisi ezinobuthi obuphezulu ezifana ne-phosgene, i-dimethyl sulfate, kunye ne-methyl chloroformate.

4. Yenza i-polycarbonate, i-diphenyl carbonate, i-isocyanate, njl.njl.

5. Kwizonyango, isetyenziselwa ukwenziwa kwamayeza okulwa nosulelo, amayeza okulwa nokuvuvukala kunye namayeza okuthomalalisa iintlungu, amayeza eevithamini, kunye namayeza enkqubo yemithambo-luvo ephakathi.

6. Kwizibulali-zinambuzane, isetyenziswa kakhulu ukuvelisa i-methyl isocyanate, ize emva koko ivelise amayeza athile e-carbamate kunye nezibulali-zinambuzane (i-anisole).

7. Izongezo zepetroli, ii-electrolytes zebhetri ye-lithium, njl.njl.
