<p>A process for the preparation of alkoxysulfates from organic compounds containing one or more nucleophilic groups by reacting said organic compound, in a water- miscible solvent selected from the group consisting of sulfur-containing solvents such as dirnethylsulfoxide (DMSO) or sulfolane, or polar solvents such as tetrahydrofuran (THF), dimethylformamide (DMF), dimethylacetamide (DMA) and hexamethylphosphoric triamide (HMPT), with an alkylene sulfate, in a non-water-miscible solvent selected from the group consisting of chlorinated solvents such as methylene chloride, chloroform, carbon tetrachloride, trichloroethane or chlorinated aromatics, such as chlorobenzene or dichlorobenzene, and non-chlorinated aromatics, such as toluene or xylenes, in the presence of a base selected from the group consisting of hydroxides, carbonates and hydrogen carbonates of alkali metals or alkaline earth metals.</p> |
