| titleOfInvention | Process for making methylolated phenol-sulfonic acid |
| abstract | Process for making aqueous solutions of methylolated phenol sulfonic acid which are substantially free from excess alkali. The process uses hydroxides of Group IIA metals as basic condensation catalysts for CH2O and phenol-sulfonic acid, and CO2 to precipitate insoluble carbonate salts at conclusion of condensation. |
