Abstract

The invention relates to a novel process for the production of iminostilbene by high temperature dehydration of iminodibenzyl on an iron oxide/potassium salt contact catalyst in the vapour phase, characterised in that an iron oxide/potassium salt contact catalyst is used containing 35 to 90% by weight of an iron compound, calculated as Fe2O3, and 7 to 35% by weight of a potassium compound, calculated as K2O, as well as 0.0 to 3.5% by weight of a chromium compound, calculated as Cr2O3, and with or without conventional promoters.
