Abstract:
The present invention relates to a method for continuously preparing a betaine aqueous solution, including the reaction of an amine with an ω-halocarboxylic acid, in the presence of water and a base. Said method is characterized in that it is carried out in a device consisting of at least two consecutive reactors (R1) and (R2), the reactor (R2) being a tubular reactor.
