Abstract

A continuous process for the production of 3-cyclohexene-1-carboxaldehyde by reaction of acrolein with butadiene at an elevated temperature and increased pressure is described in which good yields are obtained by establishing the weight ratio of the starting substances fed per time unit into a circulation reactor in relation to the reaction mixture circulated per time unit in the range of 1:5 to 1:60 and by carrying out a secondary reaction in successive reactors.
