Abstract:
There is disclosed a process for the preparation of a polyisobutyl hydroxyaromatic compound wherein the polyisobutyl substituent has an average molecular weight in the range of 400 to 5000, which comprises alkylating a hydroxyaromatic compound in the presence of an alkylation catalyst with a suitable polyisobutene containing at least 70% of a methyvinylidene isomer.
Abstract:
Platinum group metal fuel additives are effective in fuel environments which make the exclusion of water impractical. The fuels additives comprise a platinum group metal compound and a water-functional composition selected from the group consisting of lipophilic emulsifiers, lipophilic organic compounds in which water is miscible and mixtures of these. The additives are preferably effective in fuel compositions having water contents of at least about 0.01 % water by weight.
Abstract:
A lubricant-fuel mixture containing an amine salt and/or amide of a benzoic acid or thiobenzoic acid derivative, an amine salt of a phosphoric acid derivative, or certain quaternary ammonium hydroxides is effective in reducing the smoke emitted during operation of a two-cycle internal combustion engine.
