Organic isocyanates are converted to ureas by heating in the presence of certain cobalt, magnesium, chromium and lanthanide series organometallic catalysts. The process requires no water or other reactants. The process is particularly useful for removing small quantities of monoisocyanates from a solvent stream recovered from a polyisocyanate manufacturing process. The urea compounds in some instances can be recycled back into the polyisocyanate manufacturing process and reacted with polyisocyanate compounds to form biurets.

Method for converting monoisocyanates to ureas

Monoisocyanate impurities are removed from a process stream obtained when solvent is separated from a polyisocyanate product. The monoisocyanates are reacted with amine compounds at specific molar ratios to produce ureas. The ureas can be discarded by burning, landfilling or otherwise. Alternatively the ureas can be recycled back into the polyisocyanate manufacturing process, where they are formed into biuret compounds that can remain with the polyisocyanate product.

Method for removing monoisocyanates from organic solution

Phenyl isocyanates are removed from a solvent stream obtained from an MDI and/or PMDI manufacturing process by reaction in the presence of a carbodiimidization catalyst to form the corresponding N,N-diphenylcarbodiimides. The N,N-diphenylcarbodiimides can be recycled into the MDI and/or PMDI manufacturing process where they can react with MDI and/or PMDI to form uretonimines. The uretonimines have at most minimal effect on the properties and usefulness of the MDI and/or PMDI product and so can be left in the MDI and/or PMDI product.

Disclosed is a composition and use thereof for the recovery of hydrocarbon fluids from a subterranean reservoir. More particularly, this invention concerns sulfonated epoxy resin polymers comprising an epoxide-containing compound, a primary amino sulfonate, and optionally one or more of a primary monoamine alkylene oxide oligomer, that modify the permeability of subterranean formations and increase the mobilization and/or recovery rate of hydrocarbon fluids present in the formations.

Method for reducing the permeability of a subterranean formation to aqueous-based fluids

Disclosed is a composition and use thereof for the recovery of hydrocarbon fluids from a subterranean reservoir. More particularly, this invention concerns &#x3b1;-glycol containing sulfonated epoxy resin composition and method for preparing said composition. The &#x3b1;-glycol containing sulfonated epoxy resin composition is made by forming a reaction product comprising an epoxide-containing compound, a primary amino sulfonate, and optionally one or more of a primary monoamine alkylene oxide oligomer, followed by converting any unreacted epoxide groups in the reaction product to &#x3b1;-glycol groups by hydrolysis. Said &#x3b1;-glycol containing sulfonated epoxy resin compositions demonstrate good solubility in aqueous solutions and are useful for modifying the permeability of subterranean formations and increasing the mobilization and/or recovery rate of hydrocarbon fluids present in the formations.
