Yintoni i-Dimethyl carbonate CAS 616-38-6?

I-Dimethyl carbonate, ekubhekiselwa kuyo njenge-DMC, lulwelo olungenambala, olungafihliyo kunye nevumba elibi kwiqondo lobushushu begumbi. Ukuxinana kwayo (d204) yi-1.0694, indawo yayo yokunyibilika yi-4 ° C, indawo yokubilisa i-90.3 ° C, i-flash point yayo yi-21.7 ° C (evulekile) kunye ne-16.7 ° C (ivaliwe), isalathisi sayo se-refractive (nd20) yi-1.3687, kwaye ayinakutsha. Inokuxutywa phantse nazo zonke izinyibilikisi eziphilayo ezifana neealkoholi, iiketoni, kunye nee-ester nakweyiphi na indawo kwaye iyanyibilika kancinane emanzini. Ingasetyenziswa njenge methylating agent. Xa kuthelekiswa nezinye ii-agent ze-methylating, ezifana ne-methyl iodide kunye ne-dimethyl sulfate, i-dimethyl carbonate ayinayo ityhefu encinci kwaye inokuthi i-biodegraded.

Isicelo

I-Dimethyl carbonate (i-DMC) inesakhiwo esikhethekileyo se-molecular (CH3O-CO-OCH3). Isakhiwo sayo se-molecular iqukethe i-carbonyl, i-methyl, i-methoxy kunye namaqela e-carbonylmethoxy. Ngoko ke, inokusetyenziswa ngokubanzi kwiimpendulo ze-organic synthesis ezifana ne-carbonylation, i-methylation, i-methoxylation kunye ne-carbonylmethylation. Inoluhlu olubanzi kakhulu losetyenziso. Isetyenziswa kakhulu njenge-carbonylation kunye ne-methylation reagent, i-additive ye-petroli, kunye ne-raw material yokwenza i-polycarbonate (PC). Imveliso enkulu ye-DMC iye yaphuhliswa kunye nenkqubo ye-non-phosgene synthesis ye-polycarbonate. Ukusetyenziswa kwayo ngolu hlobo lulandelayo:

1. Uhlobo olutsha lwe-solvent ye-low-toxic lunokutshintsha i-solvents ezifana ne-toluene, i-xylene, i-ethyl acetate, i-butyl acetate, i-acetone okanye i-butanone kumashishini epeyinti kunye ne-adhesive. Yimveliso yemichiza eluhlaza ehambelana nokusingqongileyo.

2. I-agent ye-methylating efanelekileyo, i-carbonylating agent, i-hydroxymethylating agent kunye ne-methoxylating agent. Isetyenziswa ngokubanzi kwimimandla yokutya kwe-antioxidants, ii-agent zokukhusela izityalo, njl njl. Yinto esetyenziswa ngokubanzi kwimichiza ekrwada.

3. Indawo efanelekileyo yamachiza anetyhefu eninzi njengephosgene, dimethyl sulfate, kunye nemethyl chloroformate.

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

5. Kwiyeza, isetyenziselwa ukudibanisa iziyobisi ezichasayo, i-antipyretic kunye ne-analgesic drugs, iziyobisi ze-vitamin, kunye neziyobisi zenkqubo ye-nervous central.

6. Kwi-pesticides, isetyenziselwa ukuvelisa i-methyl isocyanate, kwaye emva koko ukuvelisa iziyobisi ezithile ze-carbamate kunye ne-insecticides (anisole).

7. Izongezo zepetroli, i-lithium battery electrolytes, njl.
