ABSTRACT:
The process of reacting a metallic halide (which metal is sodium, potassium or calcium) with sulfur trioxide including dispersing the metallic halide in the presence of an excess of sulfur trioxide or sulfur dioxide, as a dispersant, to enable handling the mixture as a slurry, completing the reaction to form the desired metallic halogen sulfonate, decomposing the metallic halogen sulfonate before or after an intermediate step to remove excess sulfur trioxide and sulfur dioxide, using combustion of sulfur to supply the heat to vaporize excess sulfur trioxide and sulfur dioxide present, and to decompose the metallic halogen sulfonate to yield the halogen, sulfur dioxide, and the sulfate of the metal, separating the metallic sulfate from the gaseous products, and separating the halogen from the sulfur trioxide and sulfur dioxide in the gaseous products by extractive distillation, or alternately treating organic material under anhydrous conditions with the metallic halogen sulfonate or its decomposition products, to halogenate or oxidize the organic material.
