摘要： Polyamines containing from 0.19 to 20.3 wt % primary amino groups are produced by hydrolyzing in a single stage an isocyanate with an excess of water, a relatively weak basic compound and a water-miscible polar solvent at a temperature from 50.degree. to 165.degree. C. The hydrolysis is conducted in a manner such that the reactants are substantially homogeneous during the reaction. The isocyanate should have an NCO-content of from 0.5 to 40 wt %. The weakly basic compound may be a carbonate or hydrogen carbonate of an alkali metal or an alkali or alkaline earth salt of a monocarboxylic or polycarboxylic acid or mixtures of such materials. The polyamines produced by this process are particularly useful in the production of polyurethanes.

摘要： Homogeneous storage stable solutions of cyanamide in a polyol are made by dehydrating a mixture of an aqueous cyanamide solution and at least one polyol under mild conditions. The aqueous cyanamide solution contains from 10 to 55 wt % cyanamide. The polyol may have a molecular weight of from 62 to 12,000. Polyether and/or polyester polyols having molecular weights from 400 to 12,000 are preferred. Mixtures of high and low molecular weight polyols which are not completely miscible with each other are also preferred. The dehydration is generally carried out at pressures less than 100 mbar and temperatures less than 130.degree. C. The product solution has a cyanamide content of from 0.1 to 50 wt % and a residual water content which is generally no greater than 1 wt %. These homogeneous and storage stable cyanamide in polyol solutions are particularly useful in the production of polyurethanes.

摘要： Polyisocyanates are produced by phosgenating a primary polyamine in the presence of at least one compound containing at least one primary and/or secondary alcoholic hydroxyl group in accordance with techniques known in the art. The reactants are used in quantities such that the equivalent ratio of primary amino groups to alcoholic hydroxyl group of from 1:0.005 to 1:0.99 is maintained during the phosgenation reaction. Where phosgenation is carried out in a two-stage process, the compound containing alcoholic hydroxyl groups must at least be present in the required quantity during the second stage. The primary polyamine may optionally be converted into a phosgenatable salt or a carbon dioxide adduct prior to being phosgenated to form the polyisocyanate. The polyisocyanates thus-produced may then be used in the production of polyurethanes or polyamines.

摘要： A compound having a terminal isocyanate group is hydrolyzed to produce a polyamine having a urethane and/or a urea and/or a biuret group. More particularly, a carbamate is made by mixing an isocyanate prepolymer having urethane and/or urea and/or biuret groups present with aqueous base solutions at a temperature of from 0.degree. to 0.degree. C. and in quantities such that the equivalent ratio of hydroxyl to isocyanate groups is between from 0,3:1 to .gtoreq.1,01 to 1. The carbamate is then treated with an acid ion exchanger to form an amine. The amine is then removed from any other material which may be present. A preferred polyamine thus-produced corresponds to the general formula: ##STR1## in which each R radical may represent a divalent straight or branched- chain aliphatic radical; a divalent cycloaliphatic radical; a 4,4'- and/or a 2,4'-dicyclohexylmethane radical; or a 2,4- and/or 2,6-methyl cyclohexane radical. Such an amine may be reacted with a polyisocyanate and optionally with other known additives to form a polyurethane plastic or foam.
