Abstract: Synthesis reactor (I) for preparing vinyl acetate monomer by catalytically reacting gaseous ethylene, acetic acid and oxygen or oxygen containing gas, is a barrier reactor. (I) comprises several reaction chambers in which the catalytic synthesis takes place, where the free conduit in each reaction chamber has dimension less than 2000 mu m and the wall of the chambers is coated with catalysts and is indirectly cooled. An independent claim is also included for a catalyst used in (I) comprising a palladium content of 0.5-10 (preferably 0.8-5) wt.%.

Abstract: 15The invention relates to a synthesis reactor and to a method for producing vinyl acetate, in which gaseous ethylene and acetic acid, in addition to oxygen or gases containing oxygen, react catalytically. The inventive synthesis reactor is a wall reactor, in which the catalytic synthesis takes place in a plurality of reaction chambers, whose free flow cross-sections measure less than 2000 pm, preferably 1000 pm and whose indirectly cooled walls are coated with a palladium-gold catalyst.

Abstract: The invention relates to a high performance catalyst containing a layer on an inert carrier body comprising noble metals from the platinum group deposited on support materials. The catalyst is characterised in that, the layer comprises platinum deposited in a washcoat consisting of A1203 which is stabilized with lanthana (La203), ceria (CeO2), which is stabilized with zirconia (ZrO2) and praseodymium (Pr6011). The supprot is promoted by sulfur-containing compounds which come from at least one of following compounds: platinum sulfite (PtSO3), sulfuric acid (H2SO4), ammonium sulfate ((NH4)2SO4), titanium oxysulfate (TiOSO4), titanium sulfate (Ti2(SO4)3), and zirconium sulfate (Zr(SO4)2).
