    Abstract: The invention relates to a method for producing ethyldimethylamine and triethylamine, comprising the steps of (i) reacting a mixture from diethylamine and dimethylamine with ethylene in the presence of a catalyst from the group of the alkali metal dimethylamides, alkali metal diethylamides and alkali metal hydrides, (ii) removing the catalyst, (iii) separating by distillation the obtained mixture into triethylamine and ethyldimethylamine and optionally diethylamine and dimethylamine, (iv) optionally returning the catalyst and the educt amines to the reaction. The inventive method allows the coupled production of ethyldimethylamine and diethylamine in a simple process.

    Abstract: The present invention describes a process for the preparation of ethyldimethylamine and triethylamine with the following steps: (i) reaction of a mixture of diethylamine and dimethylamine with ethylene in the presence of a catalyst from the group of alkali metal dimethylamides, alkali metal diethylamides and alkali metal hydrides (ii) removal of the catalyst (iii) distillation separation of the resulting mixture in triethylamine and ethyldimethylamine and optionally diethylamine and dimethylamine (iv) optional return of the catalyst and of the starting amines to the reaction. The process according to the invention permits the coproduction of ethyldimethylamine and diethylamine in a simple process.

    Abstract: A new method for preparing foamed materials involves the reaction of: (a) isocyanates; (b) compounds reactive to isocyanates of molecular weight 500-8500; and optionally (c) chain lengthening and/or crosslinking agents of molecular weight 60-499 in the presence of: (d) a propellant; and (e) a catalyst, and optionally (f) adjuvants and/or additives. Foamed materials are prepared by reaction of (a) isocyanates with (b) compounds reactive to isocyanates of molecular weight 500-8500 and optionally (c) chain lengthening and/or crosslinking agents of molecular weight 60-499 in the presence of (d) a propellant and (e) a catalyst, and optionally (f) adjuvants and/or additives. The isocyanate (a) is 2,4- and or 2,6-toluylenediisocyanate and/or 4,4, 2,2, and/or 2,4-diphenylmethane diisocyanate, and the reaction is carried out in the presence of (e1) 0.02-0.08 wt.% triethylenediamine and 0.05-0.3 wt.% of at least one aminoalkyl and/or aminophenyl-imidazole (e2) of formulas (I) and/or (II): where: R -R = phenyl, halogen, H, 1-10C linear or branched alkyl, 1-4C alkoxy, N-mono- or 1-4C N,N-dialkylamino, N-mono- or N,N-dialkylaminoalkylene, i.e. 1-4C alkyl and 2-4C alkylene, R = R , with the exception of halogen and alkoxy; Y = H, 2-4C hydroxalkyl, or hydroxypolyoxyalkyl with 2-20 alkylene oxide units, X (catalyst) = 2-6C alkylene or phenyl, Z = H, 1-4C alkylene, phenyl, 2-4C hydroxyalkyl, or 2-20C hydroxypolyoxyalkylene, and the weigh proportions of (e1) and (e2) are based on the weight proportion of component (b)(sic). Independent claims are included for: (1) A spongy plastic based on polyurethanes, prepared as above; (2) a mixture containing (e1) triethylenediamine and (e2) at least one aminoalkyl- and/or aminophenyl-imidazole at an e1 to e2 ratio of 1.6:1 to 0.06:1.
