Abstract
Process for the preparation of acrylic acid nitrile or methacrylic acid nitrile by reaction of propylene or isobutylene with air and/or with oxygen and ammonia at elevated temperatures in the presence of a catalyst, consisting of a mixture of iron oxides, bismuth, molybdenum and phosphorous and is applied on a support of silicic acid, characterized in that the reaction is carried out at temperatures between 350 and 520ºC and pressures between 0.1 and 10 atmospheres in the presence of a catalyst with a surface according to BET between 4 and 30 m2/g, containing the oxides mentioned in the atomic ratio Fe0,5-15Bi1-10Mo15P0,03-3 on silicic acid as support, combining low Fe indices with high BET values, mean Fe indices with mean BET values and high Fe indices with low BET values.
