    摘要: The invention pertains to tertiary amines used as catalysts for the preparation of polyurethane foams prepared via the catalytic reaction of a polyisocyanate with a polyol in the presence of blowing agents, etc. The tertiary amine catalysts are prepared by reacting an olefinic nitrile with aliphatic polyol having at least secondary hydroxyl functionality in a ratio less than stoichiometric for providing cyanoalkylated polyol having residual hydroxyl functionality. The resulting cyanoalkylated polyol then is reacted with a secondary amine under conditions for effective reductive alkylation.
    The tertiary amine catalysts, because of residual secondary hydroxyl functionality, provide for uniform dispersion within a polyurethane formulation; they provide for additional or extended pot life in polyurethane formulations at temperatures below reaction condition, and they are bound by reaction on cure.

    摘要: This invention relates to a process for the coproduction of propanediamines and alkylated aminopropanediamines. The process contemplates an initial cyanoethylation of ammonia under conditions for producing aminopropionitrile and modest levels of iminobispropionitrile. After separation of the iminobispropionitrile from the aminopropionitrile, the process involves the catalytic reductive alkylation of the iminobispropionitrile by reaction with an aldehyde in the presence of hydrogen to form the alkylated iminobispropionitrile followed by the catalytic hydrogenation of the nitrile group in aminopropionnitrile and iminobispropionitrile to the amine.
