Process for the preparation of piperazine derivatives, substituted in positions 1 and 4 by aralcohilic groups of a different nature, characterized in that it consists in reacting on a 1-aralcohyl-piperazine a halide of another aralcohyl, which supposes the formation of an intermediate compound which is obtained by reaction between an r- (cyclic group substituent) piperazine and an r "(substituent aliphatic group), which possesses an aldehydic function and the reduction of this intermediate compound by means of hydrogen under pressure in the presence of a catalyst, being able also use other usable preparation methods, as long as they consist of reacting a 1-aralcohyl-piperazine with an aldehyde of another aralcohyl, the reaction product being subjected to hydrogenation.
