Abstract: A process is disclosed for preparing a mixture of hydroxyl containing di- and trisulfides, from either 2-mercaptoethanol or 3-mercaptopropanol, directly in two steps, without the formation of deleterious byproducts. Precise control of process conditions (a) in a first step in which the disulfide is formed, includes oxidation of mercapto-lower alkanol with a stoichiometric amount of H.sub.2 O.sub.2 while maintaining the pH and temperature of a relatively dilute aqueous reaction mixture within a specific narrow range; and, (b) in a second step in which a predetermined portion of the disulfide is converted substantially exclusively to the trisulfide, requires controlled heating of the reaction mixture to a temperature not to exceed 100.degree. C. The process may be carried out in a single reaction vessel, and directly yields a preselected distribution of disulfide and trisulfide in the mixture.

Abstract: A method is provided for making alkali metal bisphenoxide salts by refluxing a heterogenous mixture of a non-polar organic solvent and an aqueous solution of an alkali metal bisphenoxide.

Abstract: 1-Halo-2-alkylthioethyl and 1-halo-2-arylthioethyl sulfones, having algicidal and fungicidal activity, are prepared by the addition of arylsulfenyl or alkylsulfenyl halides to alkyl or aryl vinyl sulfones.

The vinyl sulfones are halogenated to produce 1,2-dihalothioethyl sulfones, which have superior fungicidal activity, especially for tomato and celery late blight.
