Chii chinonzi Dimethyl carbonate CAS 616-38-6?

Dimethyl carbonate, inonzi DMC, imvura isina ruvara, inoonekera uye inonhuhwirira zvine hukasha patembiricha yemumba. Kuwanda kwayo (d204) i1.0694, nzvimbo yayo yekunyunguduka i4°C, nzvimbo yayo yekufashaira i90.3°C, nzvimbo yayo yekufuratira i21.7°C (yakavhurika) uye 16.7°C (yakavharwa), refractive index yayo (nd20) i1.3687, uye inobvira uye haina chepfu. Inogona kusanganiswa nezvinhu zvinenge zvese zve organic solvents zvakaita sealcohols, ketones, uye esters chero zvodini uye inonyunguduka zvishoma mumvura. Inogona kushandiswa se methylating agent. Kana ichienzaniswa nezvimwe zvinhu zvinosanganisa methylating, zvakaita se methyl iodide ne dimethyl sulfate, dimethyl carbonate haina chepfu yakawanda uye inogona kuora.

Kushandiswa

Dimethyl carbonate (DMC) ine chimiro chakasiyana chemorekuru (CH3O-CO-OCH3). Chimiro chayo chemorekuru chine mapoka ecarbonyl, methyl, methoxy uye carbonylmethoxy. Nokudaro, inogona kushandiswa zvakanyanya mukuita kweorganic synthesis reactions senge carbonylation, methylation, methoxylation uye carbonylmethylation. Ine mashandisirwo akasiyana-siyana. Inonyanya kushandiswa se carbonylation uye methylation reagent, peturu inowedzera, uye raw material yekugadzira polycarbonate (PC). Kugadzirwa kukuru kweDMC kwakagadzirwa pamwe chete nemaitiro ekugadzira polycarbonate asiri phosgene. Mashandisirwo ayo ndeaya anotevera:

1. Rudzi rutsva rwe solvent isina chepfu yakawanda runogona kutsiva solvents dzakadai se toluene, xylene, ethyl acetate, butyl acetate, acetone kana butanone mumaindasitiri ependi ne namatidza. Ichi chigadzirwa chemakemikari chegirini chine hushamwari kune zvakatipoteredza.

2. Mushonga wakanaka we methylating, carbonylating agent, hydroxymethylating agent uye methoxylating agent. Unoshandiswa zvakanyanya muminda ye antioxidants yechikafu, makemikari ekudzivirira zvirimwa, nezvimwewo. Imishonga inoshandiswa zvakanyanya.

3. Chinhu chakakodzera chinotsiva mishonga ine chepfu yakawanda yakaita sephosgene, dimethyl sulfate, uye methyl chloroformate.

4. Gadzira polycarbonate, diphenyl carbonate, isocyanate, nezvimwewo.

5. Mukurapa, inoshandiswa kugadzira mishonga inorwisa utachiona, mishonga inorwisa hutachiona uye inonyaradza marwadzo, mishonga inorwisa mavhitamini, uye mishonga yetsinga huru.

6. Mumishonga yezvipembenene, inonyanya kushandiswa kugadzira methyl isocyanate, uyezve kugadzira mimwe mishonga yecarbamate nemishonga yezvipembenene (anisole).

7. Zvinowedzerwa peturu, lithium battery electrolytes, nezvimwewo.
