Abstract: A solution (I) contains: (A) a salt of a mono or dialkyl ester of a sulfonated dicarboxylic acid; and (B) a solvent having a b.pt. greater than 250 degrees C at 1 bar. An Independent claim is also included for an aqueous polymer dispersion (II) containing the solution (I).

Abstract: Cyanoalkylation of ammonia or organic compounds containing one or more NH functions, by reaction with a carbonyl compound and hydrocyanic acid in a solvent, is carried out in two stages comprising a first stage (i) at a temperature (T1) below the boiling point of the reaction mixture, and a second stage (i) at a temperature (T2) below 150 degrees C. Cyanoalkylation of ammonia or organic compounds containing one or more NH functions, by reaction with a carbonyl compound and hydrocyanic acid (each at 1 mol per NH function to be converted) in a solvent, is carried out in two stages comprising a first stage (i) at a temperature (T1) below the boiling point of the reaction mixture, carried out until the degree of HCN conversion is at least 60% and a second stage (i) at a temperature (T2) below 150degreesC, carried out until the degree of HCN conversion is at least 90%. An Independent claim is included for alpha -cyanoalkylamines (I) obtained by the process.
