Figure 3

Glycerol conversion and selectivity as a function of reaction time over H5PW11TiO40 and H3PW12O40.

Reaction conditions: 75 °C, glycerol/acetic acid = 1:5 (molar ratio), 3 wt% catalyst loading relative to glycerol. This figure is to confirm that extending the reaction time could enhance the selectivities to DAG and TAG which are our target products.
