Abstract

Inventia se refera la un procedeu pentru obtinerea anhidridei maleice, conform caruia, în scopul optimizarii randamentului catalizatorului se determina temperatura optima necesara si se controleaza mentinereaacestei temperaturi prin masurarea temperaturii de iesire a gazelor sau a dispozitivelor de îndepartare a caldurii, în cazul folosirii unui reactor tubular cu manta, în cazul scaderii temperaturii din procesul de oxidare se introduce continuu peste catalizator un fosfat de alchil.
