    IPC: G01N33/00

    Abstract: THE INVENTION RELATES TO A METHOD OF CONTROLLING A HYDRO.-ENATION OF A STARTING MATERIAL IN A HYDROGENATION REACTOR, IN WHICH THE AMOUNT OF HYDROGEN REACTED IN THE BYDROGENATION IS FIRSTLY DETERMINED, THE RATIO OF THE AMOUNT OF HYDROGEN REACTED TO THE AMOUNT OF STARTING MATERIAL FED IN IS THEN DERIVED, THIS RATIO IS COMPARED WITH A PRESCRIBED VALUE AND, FINALLY, AT LEAST ONE PROCESS PARAMETER IS ALTERED IF THE RATIO OF THE AMOUNT OF HYDROGEN REACTED TO THE AMOUNT OF STARTING MATERIAL FED IN DEVIATES BY A PRESCRIBED AMOUNT FROM THE PRESCRIBED VALUE.

    Abstract: A process for preparing xylylenediamine, comprising the steps of ammoxidizing xylene to phthalonitrile and hydrogenating the phthalonitrile, which comprises contacting the vaporous product of the ammoxidation stage directly with a liquid organic solvent or with molten phthalonitrile (quench), partly or fully removing components having a boiling point lower than phthalonitrile (low boilers) from the resulting quench solution or suspension or phthalonitrile melt and, after the low boiler removal and before the hydrogenation, removing products having a boiling point higher than phthalonitrile (high boilers).
