Abstract

1,257,118. Catalysts &c. STAMICARBON N.V. 19 Dec., 1969 [25 Dec., 1968], No. 62031/ 69. Heading B1E. [Also in Division C2] Catalyst compositions comprising antimony or vanadium, material supported on a carrier are prepared by suspending carrier particles in a solution of a soluble compound of antimony or vanadium, agitating the suspension and gradually and homogeneously decreasing the pH of the suspension while controlling the temperature thereof, whereby precipitation of antimony or vanadium material takes place substantially entirely on the surface of the suspended carrier particles and the loaded carrier is then separated from the suspension and dried. The pH may be lowered by (i) addition of acid, e.g. nitric acid; (ii) hydrolysis of a hydroyzable compound, e.g. methylacetate, butyrolactone, ethyl chlorofomiate or formamide; composition leaves the mixer by a jet 8 to enter or (iii) oxidation of an oxidizable organic compound, e.g. methanol or sucrose with hydrogen peroxide or peroxysulphate. Specified soluble compounds of antimony and vanadium are antimony tartrate and ammonium vanadate. Carriers specified are titanium dioxide and silica. The catalyst may be calcined before use. The Examples describe (i) antimony oxide on silica (some carbon also being present) and (ii) vanadium pentoxide on titania.
