Process for converting cyclic alkyleneureas into their corresponding alkyleneamines

A process is provided for converting cyclic alkyleneureas into their corresponding alkyleneamines. The process includes reacting a feedstock comprising cyclic alkyleneureas in the liquid phase with water in an amount of from about 0.1 to about 20 mole water per mole urea moiety, at a temperature of...

More Information
Summary:A process is provided for converting cyclic alkyleneureas into their corresponding alkyleneamines. The process includes reacting a feedstock comprising cyclic alkyleneureas in the liquid phase with water in an amount of from about 0.1 to about 20 mole water per mole urea moiety, at a temperature of at least 230° C., with removal of CO2. The process may allow the efficient conversion of alkyleneureas into the corresponding alkyleneamines. In certain embodiments, the process has a high yield and low side product production.
