Applicant's summary and conclusion
- Validity criteria fulfilled:
- not applicable
- Conclusions:
- Dimethyl carbonate contains functional groups susceptible to hydrolysis. At pH values in the range of 7, no hydrolysis occurs whereas 50% of dimethyl carbonate were hydrolyzed to methanol and CO2 within one week in the presence of K2CO3 at 70°C. Similar results are to be expected for diethyl carbonate.
- Executive summary:
In this review article, hydrolysis of dimethyl carbonate is discussed. Dimethyl carbonate contains functional groups susceptible to hydrolysis. At pH values in the range of 7, no hydrolysis occurs. Conditions which favour hydrolysis are elevated temperature and alkali metal carbonates: 50% of dimethyl carbonate were hydrolyzed to methanol and CO2 within one week in the presence of K2CO3 at 70°C. Similar results are to be expected for diethyl carbonate.
