Abstract

Inventia se refera la o metoda de masurare si reglare a concentratiei substratului în timpul hidrogenarii catalitice a nitroderivatilor care se efectueaza prin masurarea continua a potentialului electrochimic redox al amestecului de reactie, la eventualele devieri de la valorile optime determinate, în prealabil, introducându-se în sistem noi cantitati de substrat sau catalizator.
