摘要： A borated bis succinimide, containing a high level of boron (preferably 1.0 to 3.0 wt. percent) is prepared by heat reacting a corresponding bis succinimide in mineral oil solution with boric acid and water at an elevated temperature of at least about 177.degree. C. Superborated succinimides prepared in the foregoing manner are useful as borating agents for ashless nitrogen containing dispersants. Lubricating compositions which incorporate nitrogenous ashless dispersants borated with the superborated succinimide of the present invention show reduced tendency to degrade engine seals manufactured from fluorine containing elastomers.

摘要： Drastic molecular weight degradation of a p-(polybutyl-substituted phenol occurs when it is heated above 65.degree. C. in the presence of BF.sub.3 -phenolate catalyst used in the preparation of said substituted phenol by the alkylation of phenol with a butylene polymer of 500 to 3000 molecular weight. Such molecular weight degradation can be substantially suppressed by providing 20 to 30 weight percent dissolved phenol in the mixture resulting from such catalytic alkylation reaction and then rapidly heating the mixture with such amount of dissolved phenol to a temperature of from 182.degree. C. up to 200.degree. C. at extant atmospheric pressure whereat the catalyst dissociates and liberated BF.sub.3 is stripped out by phenol vapors.

摘要： A mixture of BF.sub.3 gas and vapors of an alkane hydrocarbon having a normal boiling point in the range of about 80.degree. to about 125.degree. C are recovered as exhaust from the partial-condensing zone of a stripping system to which is fed 6-25 weight percent of said alkane as a liquid dissolved in the fluid reaction mixture from BF.sub.3 -phenolate catalyzed alkylation of phenol with 500-3000 M.W. liquid viscous mono-olefinic polymer of propylene or butylene and BF.sub.3 -free portion of the fluid reaction mixture is withdrawn as liquid from the partial-reboiling zone of said system. The removal of BF.sub.3 by use of such stripping operation is successful without boiling a mixture of said alkane and said alkylation reaction mixture.

摘要： Treatment of oil-soluble viscous liquid propene or butene polymers having a number average molecular weight of about 250-500 with gaseous sulfur trioxide in falling-film or static reactors yields acidic sulfonation products comprising alkenyl sulfonic acids and polymer sultones. Two-stage neutralization of the sulfonation product with ammonia or sodium hydroxide reduces the sultone content and increases the sulfonate content in the neutralized product.
