A process for producing an acyloxybenzenesulfonic acid or a salt thereof by sulfonating an acyloxybenzene (1) with the use of at least one additive selected from among carboxylic acids or esters (2), alkyl phosphates (3), polyphosphoric acids (4), amide and like compounds (6), carbonic ester compounds (7), and hydroxylic compounds (8). The process enables acyloxybenzenesulfonic acids with good hues to be produced industrially in high yields at a high selectivity and a low cost as compared with the conventional processes.
一种生产酰氧基苯磺酸或其盐的工艺,通过使用至少一种选自羧酸或酯(2)、烷基磷酸盐(3)、多磷酸(4)、酰胺和类似化合物(6)、碳酸酯化合物(7)和羟基化合物(8)的添加剂对酰氧基苯(1)进行磺化。与传统工艺相比,该工艺能以高产率、高选择性和低成本工业化生产具有良好色调的酰氧基苯磺酸。
