Process for producing metal salts of oil-soluble organosulfonic acids |
摘要 |
An improved process for producing metal salts of organosulfonic acids comprises reacting the sulfonic acid with a slight excess of the corresponding metal carbonate until the carbonate/acid equilibrium point is reached, i.e., the pH of a substantially carbonate- and bicarbonate-free sample stabilizes in the range of 6.0 to 6.38, and then adding a very small amount of stronger base to effect complete neutralization of the remainder of the sulfonic acid.
