文摘
- •
Na2O/NaX catalyst shows activity (94% methyl esters) after several uses.
- •
After the first use, the methyl esters yield is high (94–98%).
- •
The catalytic activity lost is mainly due to leaching of active sites.
- •
Leaching of Na is significantly less pronounced than K.
- •
Acetone is a better solvent to wash the catalyst than methanol.
