CONTINUOUS CONVERSION OF FRUCTOSE INTO METHYL LACTATE OVER SnO2–ZnO/Al2O3 CATALYST
The continuous conversion of fructose into methyl lactate on SnO2–ZnO/Al2O3 catalyst that may be of practical interest is efficiently performed. The supported 10SnO2–5ZnO/Al2O3 catalyst was obtained by a simple impregnation method of granular γ-Al2O3 with the aqueous solution of SnCl4 and Zn(OAc)2. The data on structural analysis, textural and acid-base parameters of synthesized samples are performed. The following optimal conditions for obtaining of 70% methyl lactate yield at 100% fructose conversion were found: use of 4.8 wt.% fructose solution in 80% aqueous methanol as initial mixture, reaction temperature of 180 °С at 3.0 МPа. Addition of Zn ions to catalyst content allows using the initial fructose mixture without potassium carbonate. 10SnO2–5ZnO/Al2O3 catalyst provides full fructose conversion at 70% methyl lactate selectivity for 6 h on stream. Spent catalyst after regeneration by washing at 120 °С restores initial activity.
