Abstract
Process for obtaining bis-phenols consisting of phenols with substituted or unsubstituted hydrogens and condensing them with aldehydes or ketones, thus forming a broth with the aryl and the aldehyde or ketone to which an acid catalyst formed indistinctly by the toluenesulfonic acid, another sulphonic acid or a sulfonic acid, in synergistic catalysis with a mercaptan.
