Abstract

1498595 Methacrylic acid TOYO SODO MFG CO Ltd 21 May 1976 [23 May 1975] 21226/76 Heading C2C [Also in Division B1] A process for producing methacrylic acid comprises reacting methacrolein with molecular oxygen or a molecular-oxygen containing gas in the vapour phase in the presence of a complex oxide catalyst having the empirical formula Mo a V b P c Ce d O e where a, b, c, d and e represent atomic ratios such that when a = 12, b = 0À01-2, c = 0À1-3, d = 0À01-2 and e assumes a value depending upon the valencies of the other components.
