Abstract: The prodn. of polyurethane (PU) foam comprises reacting (a) polyisocyanate(s); with (b) high-mol. wt. polyol(s) with at least two reactive H atoms, comprising (B1) polyoxyalkylene-polyol(s) with an OH no. of 30-500, obtd. by alkoxylating N,N'-bis(3-aminopropyl)-ethylenediamine, tripropylene-tetramine and/or tetrapropylene-pentamine with alkene oxide(s); and opt. (c) low-mol wt. chain extenders and/or crosslinkers; in the presence of (d) blowing agents. Also claimed are polyols (b1) obtd. as above.

Abstract: EN UN PROCEDIMIENTO PARA LA N - ALQUILACION DE AMINAS, EN EL QUE LOS ALCOHOLES REACCIONAN CON ALQUILAMINAS O DIALQUILAMINAS EN PRESENCIA DE HIDROGENO, SE PRODUCE LA REACCION EN UN CATALIZADOR BASADO EN SILICATO DE COBRE Y DE MAGNESIO, QUE CONTIENE CADA UNO INDEPENDIENTEMENTE ENTRE 0 Y 2 % EN PESO DE BAO, CR 2 O 3 Y/O ZN/O. EN LAS AMINAS UTILIZADAS SE TRATA DE MONO O DIETILAMINA O MONO O DIETILAMINA, EN LOS ALCOHOLES UTILIZADOS, AL , OE - DIOLES, ESPECIALMENTE DIETILENGLICOL O PENTADIOL. ESPECIALMENTE REACCIONA EL DIETILENGLICOL CON MONOMETILAMINA Y/O MONOETILAMINA DANDO N METILMORFOLINA Y/O N - ETILMORFOLINA.

Abstract: A process for the production of beta -alkoxy-nitriles which is carried out in the presence of a basic diazabicycloalkene catalyst. Production of beta -alkoxy-nitriles which involves reaction of alpha , beta -unsaturated nitriles with mono-, di- or tri- valent alcohols in the presence of a basic diazabicycloalkene of formula (1), at (-) 20-200 degrees C. n, m = 1-6; and where the 1-4 H atoms are optionally substituted by R -R ; R -R = 1-20C alkyl, 6-20C aryl or 7-20C arylalkyl. An Independent claim is also included for a production process of a gamma -alkoxy-amine by hydrogenation of the beta -alkoxy-nitrile in the presence of a hydrogenation catalyst and the catalyst of formula (1).
