PROCEDE DE PREPARATION D'ESTERS DE GLYCOL |
摘要 |
<p>In the preparation of glycol esters by the oxidation of an olefin in the presence of a catalyst comprising tellurium, wherein the accumulation of foreign metals in association with the tellurium catalyst component has an adverse effect upon the reaction, such foreign metals are maintained at low levels while the tellurium catalyst values are recovered for recycling in high yield by purging a portion of a high-boiling residual fraction produced in the distillation treatment of the reaction mixture and treating the purged portion with water and/or an aqueous alkaline solution.</p> |
