propan-2-yl 2-hydroxypropanoate

Conditions: temp:160.01; pressure:0.00; stir:; See reaction.notes.procedure_details.

Procedure: An autoclave (50 cc microclave) is charged with 8.0 g of 2-propanol, 0.2249 g of sucrose (0.6569 mmol), 119.7 mg naphthalene (internal standard) and finally with 159.7 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 0.68 mmol of isopropyl lactate is formed (26%) together with 0.237 mmol isopropyl 2-hydroxy-3-butenoate (12%). prepared The autoclave is closed charged with 20 bar of argon reaches 100° C. the mixture is heated for 20 hours under these conditions
