Abstract
The invention provides a process for synthesizing alkanolamines and/or alkyleneamines by reacting either an alkane, an alkene, or both with a source of oxygen and a source of nitrogen and, optionally, additional hydrogen to convert the alkane and/or alkene by selective partial oxidative amination to at least one of the desired end products. The invention further provides a regenerable catalyst for use in synthesizing alkanolamines and/or alkyleneamines by selective partial oxidative amination of alkanes and/or alkenes.
Claims20
A process for synthesizing at least one of an alkanolamine and an alkyleneamine, said process including the step of:
- reacting an alkane and/or an alkene with a source of oxygen, a source of nitrogen and, optionally, additional hydrogen to convert said alkane and/or alkene by partial oxidative amination to at least one of said alkanolamine and alkyleneamine.
A regenerable catalyst for use in synthesizing at least one of an alkanolamine and/or alkyleneamine by partial oxidative amination of alkanes and/or alkenes, said catalyst comprising at least one of:
- a reducible metal oxide that is reduced by reaction with a hydrocarbon moiety to a lower oxidative state, such that the metal oxide provides a lower standard free energy for the partial oxidative amination of alkanes and alkenes:
- and
- a hydrogenation/dehydrogenation metal capable of generating at least one of a hydroperoxo and peroxo intermediate.
