摘要: 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.

摘要: A process to convert cyclic alkylene ureas into their corresponding alkylene amines is provided. An exemplary process includes reacting the cyclic alkylene ureas with an amine compound chosen from the group of primary amines or secondary amines that have a higher boiling point than the alkylene amines formed during the process, wherein the process is a reactive separation process and the reaction mixture contains less than about 10 wt % of water on the basis of total weight of the reaction mixture.

摘要: The present disclosure pertains to a process for preparing hydroxyethylethyleneamines, ethyleneamines, or mixtures thereof, and/or ethylene urea derivatives thereof. The process includes reacting diethanolamine with an amine-functional compound that includes at least two —NH— units of which at least one is selected from the group of primary amine groups and cyclic secondary amine groups. The amine-functional compound includes at least one —NH—CH2-CH2-NH— unit wherein one or more —NH—CH2-CH2-NH— units in the amine-functional compound may be present in the form of cyclic ethylene urea moieties, piperazine moieties, or linear ethylene urea moieties, in the presence of a carbon oxide delivering agent.

摘要: The invention pertains to a process for converting a feedstock comprising cyclic alkyleneureas into their corresponding alkyleneamines, comprising —a CO2 removal step in which cyclic alkyleneureas are converted into their corresponding alkyleneamines by reacting cyclic alkyleneureas in the liquid phase with water with removal of CO2, —an amine removal step wherein cyclic alkyleneureas are converted in a reactive separation process into their corresponding alkyleneamines by reaction with an amine compound selected from the group of primary amines or secondary amines which have a higher boiling point than the alkyleneamines formed during the process. It has been found that the combination of a CO2 removal step and an amine removal step makes it possible to convert alkyleneureas into the corresponding amines in an efficient manner in a high reaction rate.

摘要: A process for preparing polyethyleneamines of formula NH2-(CH2-CH2-NH-)pH wherein p is at least 3 and wherein one or more —NH-CH2-CH2-NH— units may be piperazine units and/or ethylene urea derivatives of these compounds, includes reacting monoethylene glycol with an amine-functional compound having at least two —NH— units, of which at least one is selected from primary amine groups and cyclic secondary amine groups, in the presence of a carbon oxide-delivering agent. The amine-functional compound includes at least one —NH-CH2-CH2-NH— unit, and one or more —NH-CH2-CH2-NH— units may be in the form of cyclic ethylene urea moieties, piperazine moieties, or linear ethylene urea moieties. The molar ratio of amine-functional compound to monoethylene glycol is above 1.2:1 and the molar ratio of carbon oxide delivering agent to —NH-CH2-CH2-NH— units is at least 0.5:1. The process makes it possible to obtain ethylene amines and derivatives thereof without using ammonia or metal-containing catalysts.
