摘要：
Disclosed is a process for producing the magnesium salt of sulfonic acids and sulfuric esters comprising the step of neutralizing the sulfonic acids and sulfuric esters with an aqueous dispersion containing: (1) at least one neutralizing agent selected from the group consisting of magnesium oxide and magnesium hydroxide, and; (2) at least one neutralizing accelerator selected from the group consisting of benzoic acid, citric acid, malic acid, phosphoric acid, polyphosphoric acid and water-soluble salts thereof under a pH of not more than approximately 6.
