Abstract: Systems and methods for liquid-phase oxidation of an aromatic feedstock containing at least one oxidizable aromatic compound may incorporate an oxidation reactor, a separation apparatus in fluidic communication with the oxidation reactor, a solids treatment unit, and a product recovery unit in fluidic communication with the separation apparatus. The oxidation reactor may conduct liquid-phase oxidation of the oxidizable aromatic compound in the aromatic feedstock in the presence of a manganate salt to form a slurry containing liquid product and solid manganese dioxide. The separation apparatus may accept the slurry from the oxidation reactor and separate the liquid component from the solid component. The solids treatment unit accepts the solid component from the separation apparatus, treats the solid component with a basic liquid to oxidize the manganese dioxide in the solid component and form a regenerated manganate salt, which may be recycled back to the oxidation reactor.

Abstract: A system for mixing ortho-xylene with an oxygen-containing gas such as air comprises an evaporator vessel fed with the gas and having a lance projecting into the gas. The lance is provided with a metal spray nozzle for injecting droplets of hot liquid ortho-xylene into the gas stream, concurrently with the direction of flow of the gas. The metal at the surface of the spray nozzle, that in use is in contact with the liquid ortho-xylene, has a high surface hardness to resist erosion, particularly by cavitation. The system is useful in the production of phthalic anhydride by the oxidation of ortho-xylene with air, whereby the risk for deflagrations is reduced. A soft metal seal is the preferred gasket between the spray nozzle and the lance.

Abstract: A co-salt of a polyunsaturated fatty acid and a non-fatty acid is formed as a precipitate. The co-salt formed is free flowing and does not tend to agglomerate (cake) in storage. The resultant co-salt product will be easy to blend with other products to produce dietary supplements. These novel co-salt products may also tablet very well and may be added to current dietary supplement tablets.

Abstract: Oxidations of hydrocarbons, cycloalkanes and alkenes, arylalkanes, and a variety of other organic substrates are accomplished by cobalt-N-hydroxysuccinimide co-catalyzed reactions with dioxygen under unusually mild, near ambient conditions of temperature and pressure. The improved safety of the oxidation method and the high yields of product obtained make use of a unique combination of cobalt (II) complexes with N-hydroxysuccinimide. These autoxidation reactions do not have prolonged initiation times. Many of these reactions can be safely performed under normal chemical laboratory conditions and do not require specialized equipment or reagents.

Abstract: A process is described for preparing phthalic anhydride by catalytic gas phase oxidation of o-xylene, in which a gaseous mixture of o-xylene and an oxygenous gas is converted in a main reactor to a gaseous intermediate reaction product which comprises unconverted o-xylene, phthalic anhydride underoxidation products and phthalic anhydride, the heat of reaction which arises in the main reactor being removed at least partly by indirect cooling with a heat carrier medium, and the intermediate reaction product being introduced into a postreactor. The concentration of unconverted o-xylene in the intermediate reaction product is at least 1% by weight, and the sum of the concentrations of phthalic anhydride underoxidation products in the intermediate reaction product is at least 0.5% by weight. The process allows an increase in the overall yield of phthalic anhydride without or without significant deterioration in the product quality.
