Abstract
p-Menthane-7-sulfonic acid and p-menthane-2-sulfonic acid and their alkali metal, alkaline earth metal, ammonium and alkylolammonium salts are disclosed. A method for increasing the solubility of an only partially water-soluble material is presented comprising combining the material in water with the salts of p-menth-6-ene-2-sulfonic acid, p-menth-1-ene-7-sulfonic acid and their saturated derivatives as hydrotropes. p-Menth-6-ene-2-sulfonate salts are prepared from .alpha.-pinene and sulfite or bisulfite salt in the presence of a phase transfer catalyst under free radical conditions.
