  • Continuous ozonolysis of cycloalkenes into ozonides
    Patent number: 6423853
    Abstract: Continuous processes for converting cycloalkenes into ozonides in which ozone is reacted with a cycloalkene to form an ozonide solution. A portion of the solution is recycled back to the reaction, and additional cycloalkene is provided.

  • Process for the preparation of 4-phenylquinol
    Patent number: 4945183
    Abstract: Preparation of 4-phenylquinol by oxidation of biphenyl using an aqueous mixture of cerium methanesulfonic acid in which the ratio of cerous to ceric methanesulfonic acid is in the rate of 0.2 to 50 mole percent.
    Type: Grant

  • Process for treating humus materials
    Patent number: 4459149
    Abstract: Peats, mucks, soils, anaerobic sludges, lignites and other humus materials containing humic substances are slurried in the natural wet state with additional water at low pH to free humic acid from salts it may have formed in the natural state and to disperse the humic acid as a fine suspension in the water. The resulting slurry is then screened to remove coarse material such as stones, fibers and cellulosic materials that may be present, and the liquid phase compromising a dispersion of humic acid is settled or otherwise treated to remove heavy inorganic fines if present. The dispersion is then filtered to yield a relatively pure and dry filter cake, comprising crude humic acid. This product may be converted to soluble humate salts by adding a solubilizing agent such as sodium hydroxide, separating residual insolubles and drying the concentrated solution.
