Abstract
A process for manufacturing a mixture of straight-chain higher ethyleneamines and non-straight-chain higher ethyleneamines selected from branched higher ethyleneamines and cyclic higher ethyleneamines, or the urea derivatives thereof, includes reacting an amine-functional compound with an ethanolamine-functional compound in the presence of a carbon oxide delivering agent, wherein a) an amine-functional compound comprises a combination of straight-chain amine-functional compound and non-straight-chain amine-functional compound and is reacted with straight-chain ethanolamine-functional compound, or b) a straight-chain amine-functional compound is reacted with ethanolamine-functional compound comprising a combination of straight-chain ethanolamine-functional compound and non-straight-chain ethanolamine-functional compound, or c) an amine-functional compound comprising a combination of straight-chain amine-functional compound and non-straight-chain amine-functional compound is reacted with ethanolamine-functional compound comprising a combination of straight-chain ethanolamine-functional compound and non-straight-chain ethanolamine-functional compound.
