Аннотация:2,3-Butanediol (BDO) is an excellent feedstock for expanding the network of bio-based chemicals through catalytic technologies. The dehydration of BDO provides an alternative green route to important chemicals such as methyl ethyl ketone (MEK) and 1,3-butadiene (BD). In this contribution, we report on the catalytic performance of boron (BP), aluminum (AlP), titanium (TiP), zirconium (ZrP), and niobium (NbP) phosphates in BDO dehydration. The kinetic study points to three reaction pathways operating over phosphate catalysts, leading to MEK, 2-methyl-propanal (MP), and BD via intermediate 3-butene-2-ol (3B2OL) formation. The major reaction pathway is shown to involve pinacol rearrangement to MEK. The reactivity of phosphates is found to increase in the order: BP<TiP<ZrP=NbP<AlP. The best catalytic performance is achieved over AlP, which shows the highest selectivity towards MEK (78 %) at 100 % 2,3-butanediol conversion.
