A process for producing phthalonitrile, which comprises reacting o-xylene with ammonia in the presence of oxygen or a mixture thereof with inert gases and a catalyst; as the latter use is made of a mixture of oxides of bismuth, antimony, molybdenum and chromium taken in a molar ratio of 1-15:1-10:0.5-5:0.5-20 respectively or a mixture of oxides of bismuth, antimony, molybdenum and vanadium taken in a molar ratio of 1-20:1-10:0.1-15:1-20 respectively deposited onto a support.
A process for producing phthalonitrile comprising reacting o-xylene with ammonia at a temperature ranging from 350.degree. to 550.degree. C in the presence of oxygen or a mixture thereof with inert gases and a catalyst selected from the group consisting of a mixture of oxides of bismuth, antimony, molybdenum and chromium taken in a molar ratio of 1-15:1-10:0.5-5:0.5-20 respectively, and a mixture of oxides of bismuth, antimony, molybdenum and vanadium taken in a molar ratio of 1-20:1-10:0.1-15:1-20 respectively, deposited onto a support, followed by isolation of the desired product.
