The Effect of Hydrothermal Treatment of Silica-based Catalysts on their Efficiency in Acrylic Acid Synthesis via Oxidative Condensation of Methanol with Acetic Acid
Catalysts of Aldol Condensation of Acetic Acid with Formaldehyde
it had been demonstrated that mechanochemical and hydrothermal treatment of support allows increasing activity and selectivity of the catalyst in the studied process. Hydrothermal treatment (HTT) of silica increases mechanical strength of silica gel granules subjected to hydrothermal treatment, also reduction of coke formation takes place, as well as prolongation of the catalysts life. Similarly, the same approaches allow to optimize the pore structure of titanium phosphates
