PROBLEM TO BE SOLVED: To provide a heat exchange type reactor (1) the most upstream zone (31)of which can be kept at the predetermined reaction temperature even when the supply amount of a raw material compound (A) is small. SOLUTION: This heat exchange type reactor (1) is provided with: a reaction pipe (2) through which the raw material compound (A) is made to pass to obtain a product (B) by an exothermic reaction; and a reactor shell (3) which covers the periphery of the reaction pipe (2) and the inside of which is divided into a plurality of zones (31, 32) along the passing direction of the raw material compound (A) and heating media (C1, C2) are packed respectively. Heat is exchanged between the corresponding heating medium (C1 or C2) and the inside of the reaction pipe (2) in each of the divided zones (31, 32). A heater (41) is arranged for heating the heating medium (C1) packed in the most upstream zone (31) independently of the heating media (C2) packed in other zones. COPYRIGHT: (C)2006,JPO&NCIPI
