In addition to the use of the carbon-based catalyst for the acetalization reaction to produce 2-MD, to complete the process of reactive extraction, the possibility of employing the sulfonated carbon-based catalyst for hydrolysis of 2-MD back to 1,3-PDO was also evaluated. For this experiment, equal molar quantities of 2-MD and water were placed in the distillation equipment in which the carbon-based catalyst was added. The reaction was allowed to take place at 90 °C for 20 min, and the hydrolysis products were analyzed by GC.8
