Reaction Steps

In the reaction, 50 g of SnCl2.2H2O and 100 g of NH4Cl were added into a reactor (inside volume 10.0 L) as catalyst. 3.0 kg of methanol was also added into the reactor. The reactor was sealed and heated to 130° C. under stirring. A solution of 0.500 kg sucrose in 0.500 kg water was pumped into the reactor with a flow of 10.0 mL/min to carry out the reaction. After pumping all of the sucrose solution into the reactor, the reaction was kept running for another 1.5 h to complete the reaction. The resulted solution was analyzed by GC and HPLC. 80.7% of total molar yield of methyl lactate and lactic acid was obtained.
