PURPOSE: To obtain a compd. useful as detergents, surfactants, etc., from an easily available feedstock by reacting an alcoholic or phenolic org. compd. or corresponding alcoxylate with an alkoxylate org. sulfonate component in the presence of a catalyst. n CONSTITUTION: The objective is obtd. by reacting an alcoholic or phenolic org. compd. or a corresponding alcoxylate with a vinyl sulfate in the presence of an alkaline catalyst and further, a phase-transition catalyst in an aq. soln. The alkaline catalyst (e.g.; NaOH) is used at 0.1 to 3.0 wt.% of the alcohol component and the phase-transition catalyst is a quaternary ammonium salt, more particularly methyltrioctylammonium chloride. n COPYRIGHT: (C)1989,JPO |
