Abstract
Instalación para la preparación continua de alcoholatos de metales alcalinos por transalcohilación de alcoholatos de metales alcalinos de alcoholes inferiores, especialmente de metanol o etanol, con alcoholes superiores introducidos en exceso, especialmente alcoholes monovalentes alifáticos o ciclo alifáticos, y separación del alcohol de más bajo punto de ebullición, caracterizada porque comprende una columna provista de platos, en donde están dispuestas una zona de reacción inferior para la fase líquida y una zona de concentración superior pudiendo ser calentada la zona de reacción inferior de la columna a fin de conseguir de este modo la relación de reflujo apropiada del alcohol inferior en la zona de concentración superior
