Abstract: Disclosed are cationic flotation agents for separating silica from ores consisting of the monocarboxylic acid salts of polyalkylene polyamine amides wherein the amide is completely neutralized.

Abstract: A petroleum oxidate of gel resistant properties characterized by a Neut. No. between about 40 and 50, a Sap. No. between about 85 and 105, a specific gravity between about 0.99 and 1.03, a viscosity (SUS at 210.degree. F.) of between about 1200 and 2500 and a melting point of between about 85.degree. and 115.degree. F.; a calcium soap thereof having a calcium content of between about 1.2 and 1.9 wt. % and a melting point between about 155.degree. and 230.degree. F. of gel resistant properties under cutback conditions; said oxidate, calcium soap and cutback thereof respectively prepared by contacting a deasphalted naphthene base residual oil having a molecular weight of between about 300 and 900, a saturate content between about 40 and 60 wt. %, an aromatic content between about 60 and 40 wt. %, a methylene to methyl group mole ratio of between about 1:1 and 2.5:1, and an SUS viscosity (210.degree. F.) of between about 150 and 170, with air at an air rate of between about 5 and 40 SCFH/lb.

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: It has been discovered that heating C.sub.4 -C.sub.17 internal olefins to 300.degree.F to 500.degree.F for about 15 to 30 minutes in the presence of an oxo catalyst prior to hydroformylation results in a higher selectivity to primary alcohols than does the conventional hydroformylation procedure of heating all the reactants together.

Abstract: Reductive amination of C.sub.10 -C.sub.26 dialkyl internal ketones, with secondary amines, using a supported nickel catalyst, results in the production of tertiary amines in excellent yield.

Abstract: This invention concerns a process for purifying crude oximes, particularly crude n-paraffinone oximes containing carbonyl and/or chlorine contaminants, consisting essentially of treating said crude oximes with urea or thiourea, in the presence of water and lower alkanol, heating to decompose thermally unstable contaminants, filtering off the insoluble urea (or thiourea) carbonyl complexes formed, leaving a purified oxime which can be further purified by conventional purification methods such as vacuum distillation.
