High quality acyloxybenzene sulfonate production from low quality phenol sulfonates is catalysed by basic nitrogen-containing compounds

摘要

Catalysis of the production of acyloxybenzene sulfonates by reaction of phenol sulfonates containing <= 5 (especially <= 2) wt.% water with alkane carboxylic acid derivatives in aliphatic or aromatic hydrocarbons is effected using 0.1-10 wt.% of a nitrogen-containing organic compound with basic properties.
