Publication Embargo A layered titanosilicate AM-4 as a novel catalyst for the synthesis of 1-methoxy-2-propanole from propylene oxide and methanol(Elsevier, 2019) Timofeeva, Maria N.; Kurchenko, Julia V.; Kalashnikova, Galina O.; Panchenko, Valentina N.; Nikolaev, Anatoliy I.; Gil Bravo, Antonio; Zientziak; Institute for Advanced Materials and Mathematics - INAMAT2; CienciasIn this paper we report for the first time the catalytic properties of the titanosilicate AM-4 in the synthesis of 1-methoxy-2-propanol (PGME) from methanol and propylene oxide (PO). PGME is widely used as a pollution-free solvent and intermediate in the synthesis of propylene glycol methyl ether acetate, the herbicide metolachlor and in other industrial applications. We found that the catalytic properties of AM-4 could be adjusted by treatment with 0.0625–0.25 M HNO3. Increasing the concentration of HNO3 led to a decrease in basicity, which played a critical role in the reaction rate and the selectivity towards PGME. The yield of PGME decreased with increased acid concentration. The maximum conversion of PO (88.4%) and the selectivity towards PGME (92.3%) were found to be in the presence of AM-4 at 110 °C and 8 mol/mol MeOH/PO. Our results suggest that titanosilicate AM-4 has great potential for application in basic catalysis.
