Abstract: Certain substituted succinic acid, e.g., sodium alkenyl succinate, and substituted imidazoline derivatives, e.g., (ethoxypropionic acid) imidazoline, provide corrosion resistance for tin-plated steel and solvent stability to aerosol formulations containing alcohol, methylene chloride and water, which employ a hydrocarbon as the propellant.

Abstract: An improved process for production of allyl chloride which comprises (1) thermally chlorinating propylene above 300.degree. C., but below that at which substantial carbon formation is effected, (2) separating the allyl chloride from its by-products, (3) subjecting the unsaturated compounds in said by-products to a low temperature chlorination, (4) separating the 1,2-dichloropropane from the products of said low temperature chlorination, and (5) passing said 1,2-dichloropropane to a cracking furnace. The effluent from the cracking furnace can be recycled to the allyl chloride finishing system by adding it to the high temperature propylene chlorination reactor effluent. Reaction temperatures are optimized to eliminate problems caused by carbon formation in the high temperature chlorination reactor, while overall yields of allyl chloride are increased and effluents which are ecologically and economically undesirable are reduced.

Abstract: A method of preparing acrolein and methacrolein by oxidation of propylene and isobutylene over a new improved catalyst providing conversions and yields, each greater than 90% in a single-pass reactor. The improved catalyst contains within certain prescribed proportions the oxides of cobalt, iron, bismuth, molybdenum, potassium, and optionally silicon. The metals have atomic ratios ofCo.sub.3-10 Fe.sub.0.5-3.0 Bi.sub.0.5-3.0 Mo.sub.15 K.sub.0.01-0.5 Si.sub.0.5-3.0and are present in the form of oxides as pellets, spheres, or on a support. With a recycle system, a conversion of the olefin greater than 99% and yield to the aldehyde of greater than 95% are possible.
