  • Patent number: 4101583
    Abstract: Preparing indoles and intermediates therefor by reacting an N-haloaniline with a .beta.-carbonylic hydrocarbon sulfide to form an azasulfonium halide, reacting the azasulfonium halide with a strong base to form a thio-ether indole derivative, and then reducing the thio-ether indole, e.g. with Raney nickel, to form the indole compound. When an acetal or ketal of the .beta.-carbonyl hydrocarbon sulfide is used, the azasulfonium salt is treated with a base, and then with an acid to form the thio-ether indole derivative. When an .alpha.-ethyl-.beta.-carbonylic hydrocarbon sulfide is used, the resulting azosulfonium salt reacts with strong base to form a thio-ether indolenine derivative, which on reduction with Raney nickel or complex metal hydrides yields 3-substituted indoles. The aniline may be an aminopyridine to form an aza-indole compound in the process. The azasulfonium salts and thio-ether indole or thio-ether indolenine derivatives can be isolated and recovered from their respective reaction mixtures.

  • Patent number: 4101293
    Abstract: This invention relates to the preparation and use of a novel emulsifier for use in formulating storage stable coal and oil fuel mixtures. The stabilizer is prepared by reacting blends of unsaturated aliphatic and cycloaliphatic carboxylic acids with alkali metal hydroxides or amines. This stabilizing emulsifier allows for the preparation of coal and oil fuel mixtures containing up to 50 parts by weight of coal which possess superior storage stability over wide temperature ranges without the coal settling out, which undergo clean combustion thus reducing the increased air pollution normally associated with the combustion of coal or coal containing fuels and which may be used in conventional oil burning furnaces with a minimum of modification.
