Abstract
Developing efficient catalysts for the conversion of bio-renewable feedstocks to selected key chemicals such as lactic acid esters. In the present study, we are interested in designing one-pot approach for the production of lactic acid (LA)/alkyl lactates and pyruvic acid from dihydroxyacetone (DHA) over synthetic zeolite catalysts. Various synthetic BEA zeolites modified with metals (Sn, Cu, Na, Zn and Fe) were prepared using 98 ion exchange. The catalysts were tested in liquid phase using one-pot periodic autoclave (3 h, 120C). The investigated catalysts trends in following byproduct formation: lactic acid, ethyl lactate, ethyl acetate, acetic acid or acetaldehyde. The best selectivity towards lactic acid was achieved using the Cu-modified natural clinoptilolite (only 16%). The best yield towards ethyl lactate was obtained using Na-BEA zeolite (50%).
