Abstract: Impure tetra(dihydrocarbylamino)phosphonium halide is contacted with a liquid cyclic ether to dissolve the phosphonium halide and leave at least a portion of the impurities comprising at least quaternary ammonium halide or an amidophosphoxide remaining in the solid state. The solids and the liquid phase are separated from each other, an anhydrous non-solvent for the tetra(dihydrocarbylamino)phosphonium halide is mixed with the separated liquid phase to precipitate the tetra(dihydrocarbylamino)phosphonium halide, which is then separated from the liquid phase. The so-treated tetra(dihydrocarbylamino)phosphonium halide is more efficient as a catalyst for halogen exchange reactions than the original untreated tetra(dihydrocarbylamino)phosphonium halide.

The process comprises mixing at least one alkali metal with the solution at a mole ratio of alkali metal to magnesium of less than about 1:2.5, thereby forming precipitated soluble halides. Also provided by this invention is a process for reducing the amount of soluble halide in a slurry comprising a liquid organic medium, at least one viscosity reducing agent, at least one dihydrocarbylmagnesium compound, solids from the formation of said dihydrocarbylmagnesium compound, and an initial amount of soluble halide. This process comprises mixing at least one alkali metal with the slurry at a mole ratio of alkali metal to magnesium of less than about 1:1.25, thereby forming precipitated soluble halides.

Abstract: An aqueous solution of basic mercaptide salt and water-soluble peroxide are mixed together in a reaction zone and maintained under reaction conditions effective to produce a vapor phase comprising organic disulfide, and concurrently vapor phase is recovered from the reaction zone. The process is highly efficient and enables production of organic disulfides in high yield and purity. Not only is the process very easy and simple to carry out, but in addition the process (i) eliminates the need for forming an organic phase of liquid organic disulfide product and conducting a separation between such product and the total aqueous phase used in the reaction, (ii) enables efficient control of a highly exothermic reaction, and (iii) minimizes alkanesulfonic acid salt formation during the reaction.
