A METHOD FOR MANUFACTURING ALDEHYDE FROM OLEFIN, AND AN APPARATUS FOR THE METHOD

摘要

PURPOSE: A producing method of aldehyde using olefin and a reactor for the method are provided to improve the reaction conversion rate by performing an additional hydroformylation reaction process. CONSTITUTION: A producing method of aldehyde using olefin comprises the following steps: hydroformylation reacting the olefin in a main hydroformylation reactor(1) under the presence of synthetic gas of hydrogen and carbon dioxide to obtain the aldehyde product; separating a catalyst from the aldehyde product for re-circulating; and secondly hydroformylation reacting the aldehyde product in a second hydroformylation reactor under the presence of the synthetic gas.
