A catalyst comprising the oxides of bismuth, molybdenum, iron and at least one element of the Group II metals as essential components and optionally oxides of cobalt, nickel, phosphorus, arsenic and an alkali metal.

Catalyst for the manufacture of acrylonitrile and methacrylonitrile

The drying board supports a freshly coated article during drying and includes a plurality of rigid upright projections extending upward from a rigid support structure. Each projection has base connected to the support structure and terminates in an upper end. The projection upper ends define a support plane for supporting a freshly coated article during drying. The projections are spaced apart to allow air flow to the supported side of the coated article. In an exemplary embodiment, the projections are randomly positioned such as not to present a pattern on the object and yet to provide a substantially uniform support area for said support plane. The projections are asymmetrically positioned relative to the perimeter of the support structure such that one drying board may be inverted and stacked upon another such that their perimeters are congruent and such that the projections do not interfere with one another.

Certain catalysts containing iron and molybdenum plus bismuth or tellurium and nickel, cobalt, manganese, magnesium, zinc, cadmium, calcium or beryllium have been found to give especially large volumes of acrylonitrile or methacrylonitrile in a given time when boron, gallium or indium are incorporated into the catalyst.

Production of unsaturated nitriles using catalysts containing boron,

A process for conducting a combination of fixed and fluid-bed catalytic reactions is achieved by employing fixed-bed catalysts on supports within the fluid bed. The fluid-bed catalysts may move in both directions through the fixed bed, thereby giving advantages of both types of beds in one reactor.

Preparation of acrylic acid and methacrylic acid in a combination

The present invention relates to a method for the preparation of phosphomolybdic acid based catalysts utilized in the oxidation of aldehydes to unsaturated carboxylic acids by forming a solution of hydrated phosphomolybdic acid in a substantially anhydrous alkanol, adding a base to the solution, evaporating the solution to yield a catalyst powder and thereafter drying and calcining the powder to form the active catalyst. A second method for preparation is also provided and includes the steps of forming a solution of hydrated phosphomolybdic acid in a substantially anhydrous alkanol, evaporating the solution to form a concentrate, impregnating a catalyst support material with the concentrate, contacting the impregnated support with ammonia gas in an amount sufficient to form an insoluble precipitate of ammonium alkyl phosphomolybdic acid within the pore structure of said support material and thereafter drying and calcining said impregnated support material so as to form a coated catalyst.

A protective coating which is resistant to attack by basic solutions is formed from interpolymers containing maleic anhydride (MAH). An article is coated with a solution of the dissolved ammonium or amine salts of the MAH interpolymer, or if the article itself contains MAH the salts may alternatively be formed on the surface of the article by applying a basic solution containing the ammonium or amine ions. The article is then dried and heated at a temperature sufficient to form the cyclic imide structure from the ammonium or amine salt of the MAH, typically about 160 to 200.degree. C.

Imidized surface protection for maleic anhydride interpolymer articles

Monoolefins such as propylene and isobutylene are converted to the corresponding unsaturated nitriles, acrylonitrile and methacrylonitrile, respectively, by reacting a mixture of the olefin, ammonia, and a molecular oxygen-containing gas in the presence of a catalyst containing the oxides of iron, bismuth, molybdenum, and cobalt or nickel or both, and optionally an oxide of at least one element selected from the group consisting of the alkali metals, rare earth metals, tantalum and niobium, and optionally one or more of the oxides of the elements selected from the group consisting of phosphorus and arsenic.

Process for the manufacture of acrylonitrile and methacrylonitrile

Certain catalysts containing iron, bismuth and molybdenum plus nickel, cobalt, manganese, magnesium, zinc, cadmium or calcium have been found to give especially large volumes of acrylonitrile or methacrylonitrile in a given time when germanium, tin, copper, silver, chromium, ruthenium, titanium, tungsten and/or beryllium are incorporated into the catalyst.

Method for the preparation of high activity phosphomolybdic acid based

The present invention relates to a method for the preparation of phosphomolybdic acid based catalysts by forming a solution of hydrated phosphomolybdic acid in a substantially anhydrous alkyl alcohol, heating the solution to form a concentrate, and thereafter drying and calcining the concentrate support material so as to form the catalyst. Because the catalyst is prepared in alcoholic rather than aqueous solution, it has a greater activity in converting aldehydes to their respective unsaturated carboxylic acids than known phosphomolybdic acid based catalysts. Furthermore, the deammoniation step of the prior art is no longer required.

An electrochemical method is provided for maintaining the optimum activity of copper-containing catalysts for the production of amides from nitriles and water. Also provided is a process for producing amides from nitriles and water by hydrolysis.
