Abstract: This invention concerns the use of certain polycarboxylic acids and their esters as biodegradable detergents and detergent builders in the laundering of soiled fabrics.
Abstract: This invention concerns a two-step process for the preparation of ethylene from mixture of carbon monoxide and hydrogen (commonly known as synthesis gas) by reaction of said carbon monoxide/hydrogen mixtures with a carboxylic acid in the presence of one or more ruthenium catalyst complexes to form an ethyl ester of said carboxylic acid coreactant, followed by pyrolysis of said ethyl ester intermediate to ethylene.
Abstract: This invention is directed to a composition and process for the preparation of water-emulsifiable metal-working lubricant compositions having improved storage stability and superior characteristics, preferably compositions for drawing, rolling and other applications in cold metal working operations.
Abstract: This invention relates to the selective production of fatty acid derivatives from aliphatic diene substrates, such as 1,3-butadiene, in the presence of dual-function homogeneous palladium complexes and certain classes of organic tertiary nitrogen bases.
Abstract: This invention concerns the use of solubilized ruthenium-containing complexes in combination with quaternary ammonium hydroxides to effect the catalytic hydrogenation of certain classes of ortho-substituted mononitroaromatic substrates to their corresponding aryl amines.
Abstract: This disclosure is concerned with the use of supported platinum halide, Group IVA metal halide catalysts suitable for the hydroformylation of .alpha.-olefin substrates to predominantly linear, straight-chain aldehydes.

Abstract: A free-oxygen containing gas is heated while under pressure in a gas fired pressurized heater and then reacted with a hydrocarbonaceous fuel optionally in the presence of a temperature moderator in the reaction zone of a free-flow partial oxidation gas generator. The effluent gas stream from the gas generator is cooled, cleaned and optionally purified to produce a H.sub.2 +CO-containing product gas. One portion of said product gas is reacted in said pressurized heater with air in order to heat the free-oxygen containing gas going into the gas generator. Another portion of said product gas is burned with air in the combustor of a gas turbine. The exhaust gas from the combustor is passed through an expansion turbine to produce mechanical power for compressing the free-oxygen containing gas and air used in the system. The turbine may also drive a turboelectric generator. At least a portion of the flue gas from the fired pressurized heater may be introduced into the combustor or into the expansion turbine.
Abstract: This invention relates to a process for selectively separating olefins from liquid, aliphatic olefin-paraffin mixtures, said olefins and paraffins each containing from 6 to 20 carbon atoms. Separation is effected by a liquid-liquid extraction technique, using solutions of silver or copper salts in alkanols, or mixed alkanol-aliphatic polyethers solvents, as the extracting media.
Abstract: This invention concerns the use of certain biogradable detergents containing as their sole active surfactant component linear, paraffinic alcohols containing 6 to 18 carbon atoms. These fatty alcohols have good laundering activity particularly to launder soiled cotton. These alcohols can be formulated in an aqueous solution containing only builders or optionally they can be formulated as multicomponent solid detergents in the form of a homogeneous, free-flowing powder. Using standard laundering tests these materials function well as detergents at low concentration levels, exhibit comparable or superior surfactant activity to sulfonated alkylated benzenes in the removal of soil from cotton or other cellulosics.

Abstract: This invention relates to a process of catalytically converting nitrobenzene to 2-amino-3H-azepines by the reaction of the nitrobenzene with trisaminophosphine and an amine of the formula HNR'.sub.2, where R' is lower alkyl containing 1 to 6 carbon atoms.In addition, this invention concerns the catalytic hydrogenation of 2-amino-3H-azepine to epsilon caprolactam.
Abstract: This invention concerns a process for preparing beta-chloraminoalkanes from alpha olefins, chloramines and aluminum halide catalysts. The products are useful as lube oil additives and for making aziridines.
Abstract: Molding compositions or masses comprising sand and a two-component binder system are prepared. These two-component binders consist essentially of 1) polyisocyanate and 2) a low molecular weight polymethylol produced by the controlled condensation of narrow mole ratios of acetone and formaldehyde under alkaline reaction conditions followed by acidification and removal of sufficient water to produce a minimum solid content of at least 95%. These molding compositions cure so fast that they may be taken off the mold five minutes after having been cured with an amine curing agent, and reach a substantial bending strength within minutes of curing compared to prior art compositions which achieve comparable bending strength only after a period of as long as one hour.
