    摘要: Polyamines containing primary amino groups are made by hydrolyzing an isocyanate with water in the presence of a solvent which is a carboxylic acid amide. The solvent must be used in a quantity of at least 10% by weight solvent based on 100% by weight of isocyanate. The weight ratio of solvent to water must be from 3 to 200. A homogeneous phase is maintained during the hydrolysis which is carried out at temperatures of from 20.degree. to 210.degree. C. A not incorporable basic and/or metal catalyst particularly alkali metal hydroxides may be employed. The polyamines produced by this process are particularly useful for the production of polyurethanes.

    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.

    摘要: Polyamines containing primary amino groups are prepared in a single stage process by hydrolyzing an isocyanate in the presence of a catalyst incorporable through an NCO reactive group and a water-miscible aprotic-dipolar solvent. This hydrolysis is carried out at from 20.degree. to 210.degree. C. with the reactants being in substantially homogeneous phase. The isocyanate starting material has an NCO content of from 0.5 to 40% by weight. The catalyst is used in a quantity of at least 0.0001% by weight, based on 100% by weight of isocyanate compound. The water-miscible solvent is used in a quantity of at least 10% by weight, based on 100% by weight of isocyanate compound. The polyamines thus produced are particularly useful in the production of polyurethanes.
