Abstract

In a process for the production of cationic starch derivatives by reacting starch during and immediately after cooking with a quaternary ammonium salt containing epoxide groups, the alkaline starch paste with the derivatisation reagent added thereto is transported in aqueous medium from the cooking zone into a reaction by transportation means such as a pump at a temperature above 100 DEG C, at a high pH-value (e.g. 9 to 13) and at a starch concentration of more than 15% by weight. The reagent used is preferably an epoxy alkyl trialkyl ammonium salt.
