EXAMPLE 2; [0012] 30 g of the catalyst - (3% K2HPO4 and 0.5% H3PO4VAI2O3 - was charged into a stainless steel tubular reactor, having a volume of 50 cm3. The temperature of the catalytic layer was maintained at 2400C and pressures of reactor - 10 bar.[0013] 16 g/h mixture of ethyl lactate (20%), lactic acid (10%) and ethanol (60%) was vaporized through a preheating layer and supplied into the catalytic layer. The products of the reaction was condensed and analyzed. A conversion of ethyl lactate - 96%, lactic acid - 98%, selectivity to ethyl 2- ethoxypropionate was 98%, the yield of ethyl 2-ethoxypropionate was 93%. Even in 60 hours after starting the reaction, the yield of ethyl 2- ethoxypropionate was 92.3%.
