WIPO Patent Application WO/2013/077543
Kind Code:
A1
Abstract:
The present invention relates to a method for preparing phthalonitriles by the ammoxidation of xylenes. Reaction raw materials are separately supplied from a fixed layer reactor to two or more branches of the reactor, and thus, the temperature of the reactor may be easily controlled. In addition, the amount of raw material reaction gas used may be small, and the yield of the phthalonitriles may be improved. The method for manufacturing phthalonitriles is economical.
