Japanese Patent JPH0825969

B2

In the continuous process described for the preparation of dimethyldiallylammonium chloride by reaction, with stirring, of dimethylamine, allyl chloride and alkali metal hydroxide which is dissolved in water, the reaction is carried out in at least two stirred vessels arranged in the form of a cascade. Dimethylamine and allyl chloride in the stoichiometric amount in each case and only 60 to 95 mol % of the stoichiometrically necessary amount of alkali metal hydroxide are fed to the first stirred vessel and conducted through the vessel at a temperature of 20 DEG to 70 DEG C. with a residence time such that the product leaving the vessel and flowing to the further vessels still contains at most 10 mol % of free amine, mol percentages being related to the molar amount of dimethylamine employed; the alkali metal hydroxide lacking in the first stirred vessel compared to the stoichiometric amount is fed continuously to the further stirred vessels mentioned and in these vessels, at a temperature of 20 DEG to 70 DEG C., a residence time is set such that the product leaving the vessel still contains at most 2 mol % of free amine in each case. The desired dimethyldiallylammonium chloride is obtained from the product leaving the stirred vessel cascade.
