Abstract

In a process in which heat is extracted from an elongated catalyst-filled reactor through which an organic vapour is passed for partial oxidation, a stream of heat transfer fluid is passed in contact with the length of the reactor, and heat transfer fluid is added to and/or removed from said stream at intermediate points thereof to control the temperature independently of the variation of heat flow produced by the reaction occurring along the length of the reactor. The process is exemplified in respect of (a) the production of phthalic anhydride from naphthalene (1 part by weight) using air (30 parts by weight) and an initial temperature of 250-350 DEG C. rising to a hot-spot zone temperature of 550-600 DEG C. and falling to 350 DEG C. at the end of the reactor; (b) the oxidation of benzene with air to form maleic acid under the same conditions; (c) the oxidation of o-xylene to phthalic anhydride using a hot-spot temperature of 425-650 DEG C. and (d) the oxidation of 1,2,4,5-tetramethylbenzene (durene) to pyromellitic anhydride using a hot-spot temperature of 550-600 DEG C. following an initial temperature of 200-300 DEG C.
