Kopo

Dimethyl carbonate (DMC) e na le sebopeho se ikhethang sa limolek'hule (CH3O-CO-OCH3). Sebopeho sa eona sa limolek'hule se na le lihlopha tsa carbonyl, methyl, methoxy le carbonylmethoxy. Ka hona, e ka sebelisoa haholo liketsong tsa tlhaho tse kang carbonylation, methylation, methoxylation le carbonylmethylation. E na le mefuta e mengata ea ts'ebeliso. E sebelisoa haholo-holo e le carbonylation le methylation reagent, e leng se eketsang peterole, le thepa e tala bakeng sa ho kopanya polycarbonate (PC). Tlhahiso e kholo ea DMC e ntlafalitsoe hammoho le ts'ebetso ea ho kopanya polycarbonate e seng phosgene. Ts'ebeliso ea eona ke e latelang:

1. Mofuta o mocha oa tharollo e se nang chefo e ka nka sebaka sa li-solvent tse kang toluene, xylene, ethyl acetate, butyl acetate, acetone kapa butanone indastering ea pente le sekhomaretsi. Ke sehlahisoa sa lik'hemik'hale tse tala tse sireletsang tikoloho.

2. Moemeli o motle oa methylating, moemeli oa carbonylating, moemeli oa hydroxymethylating le moemeli oa methoxylating. E sebelisoa haholo masimong a li-antioxidants tsa lijo, metsoako ea tšireletso ea limela, jj. Ke thepa e tala ea lik'hemik'hale e sebelisoang haholo.

3. Sebaka se setle sa meriana e chefo haholo e kang phosgene, dimethyl sulfate le methyl chloroformate.

4. Synthesize polycarbonate, diphenyl carbonate, isocyanate, jj.

5. Bongaka, e sebelisetsoa ho kopanya meriana e thibelang tšoaetso, meriana e thibelang ho ruruha le e kokobetsang bohloko, meriana ea livithamine, le meriana bakeng sa tsamaiso ea methapo e bohareng.

6. Ho chefo e bolaeang likokoanyana, e sebelisoa haholo ho hlahisa methyl isocyanate, ebe e hlahisa meriana e itseng ea carbamate le chefo e bolaeang likokoanyana (anisole).

7. Lisebelisoa tsa peterole, li-electrolyte tsa betri ea lithium, jj.
