Abstract: A process for the continuous preparation of an aqueous solution of a salt of an alkanedicarboxylic acid of 6 to 12 carbon atoms and an alkanediamine of 6 to 12 carbon atoms by reacting the particular alkanedicarboxylic acid with the particular alkanediamine in an aqueous solution of the salt to be prepared. The aqueous salt solution is recycled from a first mixing zone via a transport zone and a second mixing zone into the first mixing zone, liquid alkanediamine and an aqueous solution of alkanedicarboxylic acid are introduced between the first and second mixing zones. Less than the equivalent amount of alkanediamine is introduced, the remaining amount of liquid alkanediamine is added after the second mixing zone, and aqueous salt solution is taken off the first mixing zone at the rate at which it is formed. The salt prepared is used for the manufacture of a nylon.

Abstract: Salts of oxaalkylenediamines of the formula I 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, and alkanedicarboxylic acids of 4 to 12 carbon atoms, terephthalic acid or isophthalic acid, which contain hydrazine, their preparation, and nylons prepared from them.
