A fluid bed process for the manufacture of vinyl acetate from ethylene, acetic acid and oxygen comprising feeding ethylene and acetic acid into a fluid bed reactor through a first inlet, introducing the oxygen into the reactor through a second inlet, co-joining the oxygen, ethylene and acetic acid in the reactor in contact with a fluid bed catalyst to produce vinyl acetate. The particle size diameter of the particulate catalyst material has a range of 60% of the particles being below 200 microns (0.1 mm) with no more than 40% of the particles being below 40 microns (0.04 mm).

Fluid bed process for the acetoxylation of ethylene in the production of vinyl acetate

A process for the preparation of a fluid bed vinyl acetate (VAM) catalyst comprising impregnating a support comprising a mixture of substantially inert microspheroidal particles with a solution comprising a metal salt of Pd and M, wherein M comprises Ba, Cd, Au, La, Nb, Ce, Zn, Pb, Ca, Sr, Sb or mixtures thereof, reducing the metal salts to form a deposit of Pd and M on the support surface and impregnating the support with at least one alkali metal salt. At least 50% of the particles used for the microspheroidal support have a particle size below 105 microns.

A process for the preparation of a fluid bed vinyl acetate (VAM) catalyst comprising impregnating a support comprising a mixture of substantially inert microspheroidal particles with a solution comprising a halide-free metal salt of Pd and M, wherein M comprises Ba, Au, La, Nb, Ce, Zn, Pb, Ca, Sr, Sb or mixtures thereof, reducing the metal salts to form a deposit of Pd and M on the support surface and impregnating the support with at least one halide-free alkali metal salt. At least 50% of the particles used for the microspheroidal support have a particle size below 100 microns, preferably below 60 microns.

A process of producing a fluid bed oxacylation catalyst for olefins and diolefins having the following formula Pd-M-A where M=Au, Cd, Bi, Cu, Mn, Fe, Co, Ce, U and mixtures thereof, A=an alkali metal or mixture thereof, and M is present in the range of from 0 to 5 wt %, comprising milling a fixed bed oxacylation catalyst precursor comprising Pd-M on a fixed support with a fluid bed catalyst aqueous binder material to form a uniform aqueous slurry, drying the aqueous slurry to remove the water to form microspheroidal particles of solid fluid bed catalyst precursor, impregnating the microspheroidal particles with a solution of alkali metal salt to form the fluid bed catalyst. The catalyst is particularly useful in the manufacture of vinyl acetate from ethylene, acetic acid and oxygen.

An apparatus for carrying out a photochemical reaction incorporates a housing (11) and a lid (15), removably affixed thereto, which together define a reaction chamber (20). The lid has an axial opening (26) therein for the passage of a light beam therethrough. Means for transmitting light energy (30) within the reaction chamber (20) having a tapered end (31) optically communicating in a sealed disposition with the axial opening (26), extends into the reaction chamber (20) and terminates in a uniquely configured end (32). The light beam received by the tapered end (31) of the means for transmitting light energy (30) is controllably dispersed within the reaction chamber (20) by the uniquely configured end (32). As such, it is possible to use an external light source to activate a photochemical reaction of the reactants, and/or a photocatalyst, contained within the reaction chamber (20). Methods for carrying out photochemical reactions in the aforementioned apparatus are likewise embodied herein.

A novel process for the isomerization of olefins which employs a photocatalytic mixed metal cluster, wherein a solution of the olefin and the cluster is irradiated causing the cluster to become catalytically active and to isomerize the olefin. The photocatalytic mixed metal cluster has the empirical formula:
