Abstract
(EN)
The present invention relates to certain alkylated 2-(2-Hydroxyphenyl)benzenesulfinic acid and 2-(2-hydroxyphenyl) benzenesulfonic acid compounds and compositions which consist essentially of 2-(2-hydroxyphenyl) benzenesulfinic acid, 2-(2-hydroxyphenyl) benzenesulfonic acid and/or substituted derivatives thereof. The compositions of the invention are useful as hydrotropes and are also of use as, or as starting materials for, surfactants, and as starting materials for the synthesis of other useful chemicals such as, polymers and resins, solvents, adhesives and biocides.
(FR)
L'invention concerne un acide 2-(2-hydroxyphényle) benzènesulfinique alkylé, et des composés et compositions d'acide 2-(2-hydroxyphényle) benzènesulfonique comprenant essentiellement un acide 2-(2-hydroxyphényle) benzènesulfinique, un acide 2-(2-hydroxyphényle) benzènesulfonique et/ou des dérivés substitués de ceux-ci. Les compositions de l'invention sont utiles comme hydrotropes ou comme matériau de départ pour les tensioactifs, et pour la réalisation de la synthèse d'autres produits chimiques, tels que les polymères, les résines, les solvants, les adhésifs, et les biocides.
