EXAMPLE 1; [0010] 30 g of the catalyst - 5% by weight NaH₂Pθ4/Siθ2 - was charged into a stainless steel tubular reactor, having a volume of 50 cm³. The temperature of the catalytic layer was maintained at 26O⁰C.[0011] 20 g/h mixture of methyl lactate with a concentration of 50% in methanol was vaporized through a preheating layer and supplied into the catalytic layer. The products of the reaction was condensed and analyzed. A conversion of methyl lactate was 94%, selectivity to methyl 2- methoxypropionate was 98%, the yield of methyl 2-methoxypropionate was 92%. Even in 60 hours after starting the reaction, the yield of methyl 2-methoxypropionate was 91.7%.
