METHOD FOR PRODUCING UNSATURATED ALDEHYDE AND UNSATURATEDE FATTY ACID

摘要

PURPOSE: A method for preparing unsaturated aldehyde and unsaturated fatty acid is provided to enable stable operation of each reactor and production with stable yield, and to reduce only the load amount of source gas of a reactor in which symptom generates. CONSTITUTION: A method for preparing unsaturated aldehyde and unsaturated fatty acid comprises a step for supplying source gas in which oxidants and molecular oxygen-containing gas are mixed to a plurality of reactors(101-A, 101-B, 102-A, 102-B) which are connected in paralle and contains a catalyst layer in order to prepare unsaturated aldehyde and unsaturated fatty.
