description The invention relates to a process for the ammonolysis of 11-aminoundecanoic acid, carried out under conditions that make it possible to limit secondary reactions that produce impurities, especially secondary amine type reactions, while considerably reducing the reaction time. According to the invention, the process comprises the following steps: i) a step of dispersing 11-bromoundecanoic acid, molten or non-molten, in an aqueous solution of ammonia, and ii) an ammonolysis step comprising the reaction of 11-bromoundecanoic acid with excess ammonia water under conditions whereby the reaction medium is stirred and heated gradually so as to obtain 11-aminoundecanoc acid with total consumption of the 11-bromoundecanoic acid.
