Abstract

Reattore multitubolare a film cadente per la solfonazione e la solfatazione in continuo di sostanze organiche allo stato liquido mediante reazione con anidride solforica (SO3 ) gassosa, caratterizzato dal fatto che ciascun elemento tubolare è fissato in modo non permanente alle piastre e comprende un ugello (10) inserito in un manicotto (20) solidale con un tubo di reazione (23). Detto ugello (10) può scorrere entro detto manicotto (20) e può essere posizionato a varie altezze rispetto a quest'ultimo, determinando con l'estremità (14) un'apertura (18) a corona cilindrica di ampiezza fissa e di altezza variabile. Tale disposizione consente di regolare la portata del liquido da solfonare. L'altra estremità di ciascun tubo (23) è inserita in un sistema di tenuta a doppia piastra.
