Abstract
The invention relates to a process for the production of 3-cyano-3,5,5-trimethyl-1-cyclo-hexanone comprising the step of reacting isophorone and hydrocyanic acid at a temperature between approximately 80 DEG and 230 DEG C. in the presence of an alkaline catalyst present in an amount of approximately 10-1 to 10-3% by weight of the reaction mixture. The process may be carried out in a batch or continuous manner and in an example of the latter an apparatus and flow sheet are described.
