Titanosilicate beads with hierarchical porosity (TiSil-HPB-60) were prepared from an anion-exchange resin and proved to be a versatile heterogeneous catalyst displaying activity both in the conversion of trioses to ethyl lactate and in the epoxidation of alkenes. In the former reaction, TiSil-HPB-60 showed higher catalytic activity compared to two well-known titanosilicate catalysts: the crystalline...
The conversion of dihydroxyacetone to ethyl lactate catalysed by different solid acids was investigated by means of High-Throughput Experimentation. A mesoporous amorphous aluminosilicate catalyst displaying very high selectivity and a good yield towards the lactate was identified. The correlation between the type of acid sites and the catalytic behaviour is discussed.
