Abstract: A process for the preparation of salts of dicarboxylic acids and diamines of the formula H2N-(R1-O)n-R2-NH2 I where R1 and R2 may be identical or different and are each alkylene of 2 to 4 carbon atoms and n is an integer from 1 to 3, which contain hydrazine in the form of hydrazine hydrate.

Abstract: A process for the manufacture of a highly concentrated aqueous solution of a salt of a dicarboxylic acid and a diamine, as well as of a nylon precondensate, by reacting an alkanedicarboxylic acid of 6 to 12 carbon atoms and a diamine of the formula NH2RNH2, where R is alkylene of 6 to 12 carbon atoms or is An aqueous solution, of lower concentration, of a salt of a dicarboxylic acid and a diamine, containing an appropriate dissolved excess of the particular dicarboxylic acid, is reacted with the particular diamine in the molten state, in an equivalent amount to the dissolved dicarboxylic acid, the reaction being carried out under superatmospheric pressure and the final reaction temperature being kept at from 140 DEG to 210 DEG C. The solution obtained is used for the manufacture of a nylon.
