Abstract
Procedimiento para la obtención de ftalidas a partir de las mezclas de reacción que se forman durante la fabricación de la ftalida mediante reducción electrolítica continua, por (a) separación por destilación de los compuestos con un punto de ebullición situado por debajo del punto de ebullición de la ftalida, a partir de la mezcla de la reacción, cuando estos compuestos estén presentes en la mezcla de la reacción, para obtener como cola una ftalida en bruto, (b) cristalización de la ftalida a partir de una fusión de la ftalida en bruto.
