Process for producing hydroxyalkyltriethylenediamine compound, and catalyst composition for the production of polyurethane resin using the hydroxyalkyltriethylenediamine compound

Abstract

To provide a process for producing a hydroxyalkyltriethylenediamine or hydroxytriethylenediamine simply and in a small number of steps without requiring multistage reaction steps; a novel catalyst composition whereby a polyurethane product can be obtained with good productivity and good moldability without bringing about odor problems or environmental problems; and a process for producing a polyurethane resin using the catalyst composition. For example, a hydroxyalkyltriethylenediamine or hydroxytriethylenediamine is produced by subjecting a mono-substituted dihydroxyalkylpiperazine and / or a di-substituted hydroxyalkylpiperazine to an intramolecular dehydration condensation reaction in the presence of an acid catalyst. Further, for example, a polyurethane resin is produced by using a catalyst composition which comprises a hydroxyalkyltriethylenediamine or hydroxytriethylenediamine (A), and an amine compound (B) having, in its molecule, one or more substituents selected from the group consisting of a hydroxy group, a primary amino group and a secondary amino group, or a tertiary amine compound (C) having a value of [blowing reaction rate constant / gelling reaction rate constant] of at least 0.5.
