METHOD OF RECOVERING CARBOXYLIC ACIDS FROM DILUTE AQUEOUS STREAMS |
摘要 |
<p>Improvement in separating lower, C2 saturated and/or C3, and/or C4, saturated and/or unsaturated mono carboxylic acids from aqueous streams via extraction by using as the extractant an organic acid or ester or mixtures thereof with a melting point below 10° C., a normal boiling point between 190 and 280° C. and a Hildebrand solubility parameter between 8 and 11 cal1/2 cm−3/2.</p> |
