Abstract: Acrolein is oxidized to acrylic acid in the presence of an oxide of W, V, Mo, and optionally>=1 of Cu, Sn, and Ce, deposited as a thin layer on the surface or an inter particulate support of diameter >= 20 microns. Thus, 25g 10-30 mesh alundum was wetted 1.03cm3 water and tumbled with 6.25g W1.2 V3 Mo12 Ox catalyst powder to give a supported catalyst. Passing 1:10:6 acrolein-air-steam over the supported catalyst at heating bath temp. 260≦̸C and contact time 2.1 sec gave conversion 93.6%, acrylic acid selectivity 93.7% and yield 87.7%, and acetic acid yield 0%, with an exotherm of 9≦̸C.

Abstract: Maleic anhydride(I) was manufd. from butane by oxidn. over catalysts of high life and of the type VaPbVcOx (a,b = 0.1-10, c = 0.01-5, X = Numbers of O atom which satisfy the atomic value of other atoms) Thus, 33.6g V2O5 in 438ml concentrated HCl was treated with 31.3g VO2(C2H3O2) 2HO2, refluxed 1hr, treated with H3PO4, refluxed, dried, and used at 482≦̸C to prepare I in 47-50% yield from a 1:100 butane air mixt.
