This invention generally provides blocked isocyanate compositions and more specially blocked isocyanate compositions useful in aminoplastic resins, phenoplastic resins or latex resins for composite wood products, wherein the blocked isocyanate composition is obtained by adding alkylene carbonate to a blocked isocyanate (A), wherein the blocked isocyanate (A) is obtained by reacting a secondary amine (al) with a reaction product (a2) of a polyfunctional isocyanate and a monofunctional hydroxyl containing compound, wherein the monofunctional hydroxyl containing compound is a polyethylene oxide polymer with terminal hydroxyl group, polyoxyethylene-polyoxypropylene monols or a mixture thereof, wherein the portion of blocked isocyanate (A) by weight percentage of the blocked isocyanate composition is between 50 and 90, preferably between 60 and 80. The compositions are stable at room temperature when mixed with active hydrogen containing compounds. The composition has low visicosity and after de-block has the potential to reduce free formaldehyde levels in formaldehyde containing resins.

A process for extracting a phosgene compound, comprising providing a membrane extracting unit comprising at least one extracting cell that comprises at least one membrane contactor module having at least two sides, a gas side and a liquid side; letting an initial gas stream comprising a phosgene compound flow on the gas side of the membrane contactor module; and letting an extractant liquid stream, suitable for dissolving a phosgene compound, flow on the liquid side of the membrane contactor module so that the extractant liquid stream absorbs the phosgene compound from the initial gas stream and provides a second extractant liquid stream enriched with the phosgene compound.

Abstract

Process for preparing rigid polyurethane or urethane-modified polyisocyanurate foams from polyisocyanates and polyfunctional isocyanate-reactive compounds in the presence of blowing agents wherein the polyfunctional isocyanate-reactive compounds comprise a polyether polyol having a hydroxyl number of between 50 and 650 mg KOH/g obtained by reacting a polyfunctional initiator first with ethylene oxide and subsequently with propylene oxide wherein the propoxylation degree is between 0.33 and 2 mole propylene oxide per active hydrogen atom in the initiator and wherein the molar ratio of ethylene oxide to propylene oxide in said polyether polyol is at least 2.
