Elevated temperature, gas-phase, catalyzed processes for preparing HCN in which induction heating is used as a source of energy, and novel apparatus for carrying out said processes.

Induction-heated reactors for gas phase catalyzed reactions

Provided is a selective hydrogenation process for producing aminonitriles by contacting the corresponding dinitriles with a hydrogen-containing fluid in the presence of a hydrogenation catalyst, a solvent and an additive for improving the yield of and/or selectivity to the aminonitrile.

Aminonitrile production

This invention provides a process for the catalytic partial oxidation of a hydrocarbon feedstock by contacting a feed stream including a hydrocarbon feedstock and an oxygen-containing gas with a catalyst in a reaction zone maintained at conversion-promoting conditions effective to produce an effluent stream including carbon monoxide and hydrogen. The process of this invention is characterized by using an unsupported porous catalyst containing rhodium, such as rhodium foam.

Rhodium foam catalyst for the partial oxidation of hydrocarbons

Provided is a selective hydrogenation process for producing aminonitriles by contacting the corresponding dinitriles with a hydrogen-containing fluid in the presence of a hydrogenation catalyst, a solvent and an additive for improving the yield of and/or selectivity to the aminonitrile. The additive comprises a carbon monoxide; a tetraalkylammonium hydroxide compound; a tetraalkylphosphonium hydroxide compound; a multi-centered metal carbonyl cluster; an organic isonitrile; a cyanide compound having at least one cyano group bound to other than a carbon atom; and afluoride compound.

Process for hydrogenating dinitriles in aminonitriles

Process for converting a dinitrile to a diamine and optionally an aminonitrile, in which a Group VIII element catalyst is treated with a modifier either before or during a substantially solvent-free hydrogenation reaction in which the dinitrile is contacted with hydrogen in the presence of the catalyst.

Environmentally friendly process for the hydrogenation of dinitriles

A process for making 6-aminocaproic acid by hydroformylating 3-pentenenitrile to produce 3-, 4-, and 5-formylvaleronitrile (FVN mixture), oxidizing the FVN mixture to produce 3-, 4-, and 5-cyanovaleric acid; hydrogenating the resulting product to produce 6-aminocaproic acid, 5-amino-4-methylvaleric acid, and 4-amino-3-ethylbutyric acid; and isolating 6-aminocaproic acid from the reaction product. The resulting 6-aminocaproic acid can be cyclized to produce caprolactam.

Production of 6-aminocaproic acid

A process for making alkyl 6-aminocaproate by hydroformylating 3-pentenenitrile to produce 3-, 4-, and 5-formylvaleronitrile (FVN mixture), converting the FVN mixture to alkyl 3-, 4-, and 5-cyanovalerate by either oxidative esterification of the FVN mixture or oxidation of the FVN mixture followed by esterification; isolating alkyl 5-cyanovalerate; and hydrogenating the alkyl 5-cyanovalerate to produce alkyl 6-aminocaproate. The resulting alkyl 6-aminocaproate can be cyclized to produce caprolactam.

Production of alkyl 6-aminocaproate

A process for the production of 6-aminocaproamide comprising reacting 5-cyanovaleramide with hydrogen in the presence of a metal catalyst. The 6-aminocaproamide is useful, for example, in the production of caprolactam and nylon 6.

Process for preparing 6-aminocaproamide

This invention relates to improvements in processes and catalysts for elevated temperature, gas phase, catalyzed reactions in general; it is particularly illustrated by reference to the manufacture of hydrogen cyanide.

Gas phase catalyzed reactions

Provided is a selective hydrogenation process for producing aminonitriles by contacting the corresponding dinitriles with a hydrogen-containing fluid in the presence of a hydrogenation catalyst, a solvent and a cyanide compound.

A catalyst composition is disclosed which includes a p-aramid polymer supporting a catalyst agent. The composition exhibits improved catalytic activity when compared with a similar composition using m-aramid polymer as the support. The composition contemplates shaped and formed catalyst structures using p-aramid particles and fibers, as papers and fabrics, and as, for example, honeycomb and mats.

Aramid polymer catalyst supports

A process for selectively hydrogenating a dinitrile to an aminonitrile is provided. The process comprises contacting a dinitrile with a hydrogen-containing fluid in the presence of a solvent comprising an alcohol or liquid ammonia, at least one metal catalyst, and a carbonyl group-containing additive such as, for example, organic amides, organic esters, salts of carboxylic acids or urea.

Process for producing 6-aminocapronitrile and/or hexamethylenediamine by hydroformylating 3-pentenenitrile, isolating a formylvaleronitrile (FVN) mixture from the hydroformylation reaction product, reductively aminating the FVN mixture and isolating the desired product.

Process for the production of 6-aminocapronitrile and/or

An improved induction heated reactor apparatus involving a reaction zone with inlet and outlet and containing an array of electrically conductive catalyst entities (susceptor entities) comprising pellets, rings, or rods containing a core externally coated with a substantially uniform and complete catalyst metal (e.g., platinum, platinum-iridium alloy, or platinum-rhodium alloy) wrap, coating, or surface impregnated, or containing the catalyst metal as a foam which are inductively heated to produce chemical product from a catalytic reaction. Such an apparatus is particularly useful in the catalytic generation of HCN at elevated temperatures.
