| description | The method of inhibiting the polymerization of a mono-ethylenically unsaturated carboxylic acid, anhydride, ester or neutralized or partially neutralized sail, e.g., an acrylic acid or ester, in an aqueous solution and in the presence of oxygen, the method comprising the step of mixing with the aqueous solution an inhibitor comprising (i) at least 50 ppm of an N-oxyl compound, e.g., 4-hydroxy-TEMPO, and (ii) a manganese ion, the N-oxyl compound and manganese ion present in a N-oxyl compound to manganese ion weight ratio of 50:1 to less than 100:1 based on the mono-ethylenically unsaturated carboxylic acid, anhydride, ester or salt,
L'invention concerne un procédé pour inhiber la polymérisation d'un acide carboxylique, d'un anhydride carboxylique, d'un ester carboxylique, ou d'un sel carboxylique neutralisé ou partiellement neutralisé, à insaturation monoéthylénique, par exemple un acide ou un ester acrylique, dans une solution aqueuse et en présence d'oxygène, le procédé comprenant l'étape de mélange à la solution aqueuse d'un inhibiteur comprenant (1) au moins 50 ppm d'un composé N-oxylé, par exemple, 4-hydroxy-TEMPO, et (ii) un ion manganèse, le composé N-oxylé et l'ion manganèse étant présents en un rapport composé N-oxylé à ion manganèse compris entre 50/1 et moins de 100/1, rapporté à l'acide, l'anhydride, l'ester, ou le sel carboxylique à insaturation monoéthylénique. |
