This invention relates to a preparation for a polyurethane foam and a polymer polyol preparation for a polyurethane foam, each of which exhibits high coloration and discoloration inhibition properties over a long period of time when stored, and to a composition for a polyurethane foam, which is excellent in storage stability and is preferable as a resin premix. The composition comprises (i) at least one polyol, (ii) a compound having a P&#x2550;N bond, (iii) an antioxidant having a hydroxyphenyl group, (iv) at least an acid and/or its salt, (v) a catalyst for polyurethane foam production and (vi) a blowing agent.

A method for treating an isocyanate residue, which comprises carrying out a thermal decomposition reaction of a carbamate that is produced by the reaction among an amine, urea and/or an N-unsubstituted carbamic acid ester and an alcohol to produce a decomposition solution, separating an isocyanate and the alcohol from the decomposition solution to produce the isocyanate residue, and bringing the isocyanate residue into contact with high-pressure/high-temperature water to decompose the isocyanate residue into an amine; and a method for treating a carbonate, which comprises bringing the carbonate into contact with high-pressure/high-temperature water to decompose the carbonate into an alcohol.
