| titleOfInvention | Reduction of sensitivity of strong acid or strong acid composition to water, and strong acid composition of low sensitivity to water |
| abstract | PURPOSE: To reduce the sensitivity of a strong acid to water, and to stabilize a liquid strong acid when exposed to water, by admixing a polar neutral solvent to the strong acid or a strong acid compsn. n CONSTITUTION: This method comprises admixing a polar neutral solvent, e.g. N,N-dimethyl formaldehyde, with a strong acid, e.g. p-toluene sulfonic acid, or a strong acid compsn., by at least 10% pref. 20-65% of the whole volume of the admixt., and exposing the strong acid to water to inhibit crystallization of the strong acid. The liq. strong acids used, e.g. toluene-sulfonic acid composition as a catalyst at various industrial processes contg. polymerization, are very sensitive to water and crystallize in a short time. By this method, sensitivity of liq. strong acid to water is reduced to the extent that it can be exposed to the air without crystallization. n COPYRIGHT: (C)1991,JPO |
