Dimethyl carbonate (DMC) e na le sebopeho se ikhethang sa molek'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 ho li-organic synthesis reactions tse kang carbonylation, methylation, methoxylation le carbonylmethylation. E na le mefuta e mengata haholo ea lisebelisoa. Haholo-holo e sebelisoa e le carbonylation le methylation reagent, addititive peterole, le thepa e tala bakeng sa synthesizing polycarbonate (PC). Tlhahiso e kholo ea DMC e tsoetse pele hammoho le ts'ebetso ea non-phosgene synthesis ea polycarbonate. Tšebeliso ea eona ke e latelang:
1. Mofuta o mocha oa motsoako o tlaase oa chefo o ka nka sebaka sa li-solvents tse kang toluene, xylene, ethyl acetate, butyl acetate, acetone kapa butanone liindastering tsa pente le tse khomarelang. Ke sehlahisoa sa lik'hemik'hale tse tala tse nang le tikoloho.
2. Mokelikeli o motle oa methylating, carbonylating agent, hydroxymethylating agent le methoxylating agent. E sebelisoa haholo masimong a li-antioxidants tsa lijo, lisebelisoa tsa tšireletso ea limela, joalo-joalo Ke lisebelisoa tse sebelisoang haholo tsa lik'hemik'hale.
3. Se ka nkelang lithethefatsi tse chefo haholo tse kang phosgene, dimethyl sulfate, le methyl chloroformate sebaka se loketseng.
4. Kopanya polycarbonate, diphenyl carbonate, isocyanate, joalo-joalo.
5. Meriana, e sebelisetsoa ho kopanya lithethefatsi tse thibelang likokoana-hloko, lithethefatsi tsa antipyretic le analgesic, lithethefatsi tsa vithamine, le lithethefatsi bakeng sa tsamaiso ea methapo e bohareng.
6. Likokoana-hloko, e sebelisoa haholo-holo ho hlahisa methyl isocyanate, ebe joale ho hlahisa lithethefatsi tse itseng tsa carbamate le likokoanyana tse bolaeang likokoanyana (anisole).
7. Lisebelisoa tsa peterole, li-electrolyte tsa betri tsa lithium, joalo-joalo.
