- Molecular formula:C9H8O4
- Molecular Weight:180.16
Yield:4376-18-5 99%
Reaction Conditions:
with 5 wt percent zeolite NaY-Bf at 180; for 5 h;Autoclave;Green chemistry;
Steps:
Methylation of carboxylic acids with dimethylcarbonate. General procedure
General procedure: Into a stainless steel pressure microreactor of capacity 17 mL was charged 5 wt % of zeolite NaY-Bf, 100 mmol of carboxylic acid, and 300-400 mmol of dimethyl carbonate, the reactor was hermetically closed, and the reaction mixture was heated at 180-200°C for 5 h. On completion of the reaction the reactor was cooled to room temperature, opened, the reaction mixture was filtered through a bed of Al2O3. Unreacted dimethyl carbonate was distilled off, the residue was distilled at atmospheric pressure or in a vacuum, or it was crystallized from ethanol.
