Abstract
Procédé pour doser des composés organo-aluminiques dans leurs solutions, par réaction avec un alcool tertiaire, une amine tertiaire ou un ether. A la solution du composé organo-aluminique, qui se trouve dans le ballon 1, on ajoute d'un seul coup un exces de réactif (alcool tertiaire, amine tertiaire ou éther), qui se trouve dans le récipient 4, et on mesure la variation de température. Le récipient réactionnel est construit de telle façon que la réaction soit adiabatique. La mesure est précise, même si la concentration de l'organo-aluminique est inférieure à 10 millimoles/dm**3. Elle permet, en fabrication, une surveillance automatique continue.
