| titleOfInvention | Method of inhibiting polymerization and fouling in acrylic acid and acrylate processes |
| abstract | The present invention relates to a process for inhibiting the polymerization of mono-ethylenically unsaturated carboxylic acids, their anhydrides, esters or neutralized salts or partially neutralized salts, such as acrylic acid or their esters, in aqueous solution in the presence of oxygen, The method comprises mixing said aqueous solution with an inhibitor comprising (i) 50 ppm or more of an N-oxyl compound, such as 4-hydroxy-TEMPO and (ii) manganese ions, wherein said N-oxyl compound and manganese Ion is present in a weight ratio of N-oxyl compound to manganese ion of less than 50: 1 to less than 100: 1, based on the monoethylenically unsaturated carboxylic acid, an anhydride, ester or salt thereof. |
