Reaction Conditions

Reaction Steps

An autoclave (50 cc microclave) is charged with 8.0 g of ethanol, 0.2252 g of sucrose (0.6578 mmol), 118.9 mg naphthalene (internal standard) and finally with 160.0 mg Sn-BEA (prepared according to U.S. Pat. No. 6,306,364). The autoclave is closed, charged with 20 bar of argon and heated to 160° C. After the temperature reaches 100° C., the mechanical stirrer is started (500 rpm) and the mixture is heated for 20 hours under these conditions. GC-analysis of the reaction mixture shows that 1.03 mmol of ethyl lactate is formed (39%) together with 0.316 mmol ethyl 2-hydroxy-3-butenoate (16%).
