An alternative non-toxic route for the synthesis of pentamethyldiethylenetriamine using methanol as a greener and cheaper methylating reagent is presented. The reaction proceeds fast and selectively over composite copper catalysts, yielding pentamethyldiethylenetriamine with a yield of 75% and resistance to sintering.
Pentamethyldiethylenetriamine is a permethylated polyamine that is widely used to prepare foam polyurethane. The current technology for its synthesis relies on diethylenetriamine methylation with formaldehyde under H-2. This route is selective, but the use of formaldehyde raises safety and environmental concerns. Herein we present an alternative non-toxic route using methanol as greener and cheaper methylating reagent. The reaction proceeds fast and selectively over composite copper catalysts with a pentamethyldiethylenetriamine yield of 75% and resistance to sintering.
