  • Gasoline compositions
    Patent number: 4116644
    Abstract: Fuel induction systems of internal combustion engines are cleansed by operating the engine on a gasoline containing a detergent amount of the condensation product of phenol, and preferably a high molecular weight alkylphenol, an aldehyde, and an amine having a H--N< group. Effectiveness is improved, especially when using a large amount of the detergent composition or when using the detergent composition with water intolerant gasolines, by inclusion of a demulsifier containing an aryl sulfonate, a polyether glycol, and an oxyalkylated phenol formaldehyde resin.The concentrates of this invention also include one or more alcohols of about 4 to about 10 carbon atoms, an aromatic solvent, and a corrosion inhibitor.This invention also comprises gasolines containing these concentrates; the concentrate being present in a small amount that confers carburetor detergency properties to the gasoline.

  • Gasoline additive concentrate composition
    Patent number: 3994698
    Abstract: Fuel induction systems of internal combustion engines are cleaned by operating the engine on a gasoline containing a detergent amount of the condensation product of phenol and preferably a high molecular weight alkylphenol, an aldehyde and an amine having a H--N < group. Effectiveness is improved by inclusion of a mineral polyolefin having an average molecular weight of from about 300-2000. The condensation product is also effective in other distillate fuels.
    Type: Grant
    Filed: June 30, 1975
    Date of Patent: November 30, 1976
    Assignee: Ethyl Corporation

  • Preparation of aniline from phenol and ammonia
    Patent number: 3965182
    Abstract: Aromatic amines are made by reacting a phenol with aluminum nitride and either ammonia or a primary or secondary amine at temperatures from 200.degree.-600.degree.C. For example, 2,6-dimethyl-phenol reacts with aluminum nitride and ammonia to yield 2,6-dimethylaniline.
