Abstract
1450632 Preparation of polyarylpolyamines E BILLER 31 May 1974 [1 June 1973 17 Sept 1973 29 April 1974] 24164/74 Heading C2C Polyarylpolyamines are prepared in a multistage process by (a) reacting an aromatic amine which contains at least one hydrogen atom in the amine group and which must be unsubstituted in at least one of positions 2, 4 or 6 with an aliphatic aldehyde in the absence of a catalyst to form a precondensate; (b) removing at least some of the water after the reaction and (c) rearranging the precondensate in the presence of a catalyst which is an acid salt of the aromatic amine or of its condensation product with a saturated aliphatic aldehyde or a. mixture of saturated aliphatic aldehydes in a polar, water-soluble organic solvent, or in the presence of aqueous mineral acid or an aqueous acid salt of the aromatic amine and the catalyst used is either washed out with water and used again or neutralized with alkali. The examples describe the preparation of diaminodiphenylmethanes.
