Resumen
In 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 ...

In 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. [--]
