| abstract | ABSTRACT OF THE DISCLOSURE p-Menthane-7sulfonic 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. Salts of four alpha- en beta-pinene derived sulfonates have been indentified as effective hydrotropes in aqueous media. These compounds are identified by their struc-tural formulas below; where M is an alkali metal, alkaline earth metal, ammonium or alkylolammonium cation. |
