Abstract: Compounds containing ester groups and tertiary amino groups and optionally hydroxyl groups are made by reacting optionally hydroxyfunctional acetoacetic acid esters of monofunctional or polyfunctional alcohols (particularly polyfunctional polyether polyols) with primary/tertiary polyamines (particularly diamines). These compounds are useful as optionally incorporable catalysts for the isocyanate addition reaction in the production of polyurethane foams by the isocyanate polyaddition process.

Abstract: N,N-disubstituted monourethanes and oligourethanes are produced by reacting (a) N-aliphatically and/or N-cycloaliphatically and/or N-araliphatically substituted monourethanes and/or oligourethanes with an alkylating agent in the presence of a solid alkali metal hydroxide. No solvent need by employed but if a solvent is used, that solvent should be an aprotic organic solvent. The alkali metal hydroxide must be used in an equivalent amount. A phase transfer catalyst may optionally be employed. The N,N-disubstituted urethanes obtained by this process are useful in the production of dyes, pharmaceutical products and thermostable synthetic materials.
