Abstract

1481641 Oxidizing aldehydes NIPPON ZEON CO Ltd 14 March 1975 [14 March 1974] 10882/75 Heading C2C [Also in Division B1] Unsaturated carboxylic acids are made by the vapour phase oxidation of unsaturated aldehydes with O 2 in the presence of a catalyst comprising an oxidic composition of empirical formula MO 12 P 0À1-8 Cr 0À1-8 Q 0À1-8 L 0À01-6 O f where Q=K, Rb, Cs and/or Tl and L = Sr, Zn, Cd, B, Pb, V, Nb, Bi and/or W. Preferred reaction conditions are 300-500‹ C., up to 15 atm. and a contact time of 0.1-20 s. Acrylic and methacrylic acid are made in the examples from acrolein and methacrolein respectively with a feed gas containing the aldehyde, O 2 , N 2 and H 2 0.
