摘要： The present invention relates to a new organic heterocyclic isocyanate which is the reaction product of an organic diisocyanate and an amino or hydroxy nitrile. The invention also relates to a process of producing such isocyanates by reacting an excess of the diisocyanate with the nitrile under conditions under which the nitrile will not decompose and then maintaining the reaction mixture at an elevated temperature until the isocyanate nitrile adduct cyclizes. The reaction may be carried out in the presence of a catalyst for isocyanate addition reactions. Additionally, the invention relates to a process for the production of polyurethane by the reaction of the heterocyclic isocyanates with compounds carrying at least two isocyanate reactive hydrogen atoms per molecule.

摘要： The invention relates to new polyamines, preferably containing polyether segments, a process for their preparation and their use as starting components for the production of polyurethane resins. The process involves producing ketimines, aldimines or enamines containing hydroxyl groups by reacting a hydroxyl amine with an aldehyde or ketone and removing the water by product. The ketimine, aldimine, or enamine is then reacted with an NCO prepolymer wherein the hydroxyl group of the material reacts with the isocyanate group without disturbing the blocked amine. This polyaddition product is then hydrolyzed to unblock the high molecular weight polyamine.

摘要： This invention relates to an improved process for the production of a mixture of low molecular weight polyhydric alcohols, hydroxy aldehydes and hydroxy ketones by condensing formaldehyde hydrate in the presence of calcium hydroxide as catalyst and in the presence of compounds capable of enediol formation as co-catalyst. A formaldehyde-containing enediol formation as co-catalyst. A formaldehyde containing solution of the co-catalyst in water and, optionally, low molecular weight monohydric or polyhydric alcohols and/or relatively high molecular weight polyhydroxyl compounds is adjusted to a pH value of from 9 to 12, preferably from 9 to 10, by the addition of calcium hydroxide at a temperature of from 80.degree. to 110.degree. C., preferably from 90.degree. to 105.degree. C., so that condensation of the formaldehyde hydrate is initiated. An aqueous formalin solution and/or paraformaldehyde dispersion containing from 20 to 65%, by weight, of formaldehyde and calcium hydroxide are then introduced in such a quantity that the reaction mixture is maintained at a pH value of from 7.5 to 9.5, preferably from 8 to 9, at a temperature of from 80.degree. to 110.degree. C., preferably from 90.degree. to 105.degree. C. The concentration of formaldehyde is maintained at from 0.5 to 10%, by weight, preferably from 1.2 to 6%, by weight, based on the reaction mixture as a whole, throughout the condensation reaction. Finally, the residual quantity of formaldehyde, amounting to from 0.5 to 10%, by weight, is optionally removed by further condensation at pH values below 7 or by reaction with other compounds that are reactive with formaldehyde hydrate.
