Abstract: A method for making metal organic frameworks (MOFs) includes the step of dissolving metal salts in deionized water to form first solution, followed by adding a cyclic propyl phosphonic anhydride reagent to the first solution to form a second solution. The second solution is heated to form a reaction mixture containing MOF crystals, and is then cooled. The MOF crystals are filtered therefrom, washed and dried. To make metal organic framework-based thin film nanocomposite membranes, the MOF crystals are mixed with an m-phenylene diamine aqueous solution to form a mixture, which is then poured on a top surface of an ultrafiltration membrane substrate to form a first intermediate membrane structure. The first intermediate membrane structure is dried, and trimesolyl chloride in n-hexane solution is poured thereon to form a second intermediate membrane structure, which is cured to form an MOF-based thin film nanocomposite membrane, which is then rinsed and dried.

Abstract: A process is provided for converting one or more cyclic ethylene ureas into corresponding ethylene amines and carbon dioxide. The process may include contacting water with one or more cyclic alkylene urea compounds comprising one or more cyclic alkylene urea moieties in a reaction vessel at a temperature of 150 to 400° C., optionally in the presence of an amine compound selected from the group of primary amines, cyclic secondary amines and bicyclic tertiary amines. The mole ratio of water to cyclic alkylene urea moieties is in the range of from about 0.1 to about 20. In the reaction, at least a portion of the cyclic alkylene urea moieties are converted to corresponding alkylenediamine moieties and carbon dioxide. The process may further include removing the carbon dioxide from the liquid reaction mixture in a stripping vessel by feeding a stripping fluid to the stripping vessel. Further, the process may include removing a carbon dioxide-containing stripping fluid.

Abstract: A process is provided for converting cyclic alkyleneureas into their corresponding alkyleneamines. The process includes, in a first step, converting cyclic alkyleneureas into their corresponding alkyleneamines by reacting cyclic alkyleneureas in the liquid phase with water with removal of CO2, so as to convert from about 5 mole % to about 95 mole % of alkyleneurea moieties in the feedstock to the corresponding amines. The process further includes, in a second step, adding an inorganic base and reacting cyclic alkylene ureas remaining from the first step with the inorganic base to convert them partially or completely into their corresponding alkyleneamines. Certain embodiments of the two-step process obtain a high conversion of cyclic alkyleneureas, while using substantially less strong inorganic base. Certain embodiments of the process process also show a higher selectivity to amines than prior art processes.
