Catalytic Conversion of Dihydroxyacetone to Methyl Lactate Over SnO2/Al2O3 Catalysts
The conversion of dihydroxyacetone solution in methanol to methyl lactate has been studied in flow regime using xSnO 2 /Al 2 O 3 -supported catalysts that have been characterized by XRD, low-temperature nitrogen (ad)desorption analysis, and UV-Vis spectroscopy. It is found that Lewis and Brønsted ac...
