摘要：

The rhodium catalyzed cooligomerization of conjugated methyl linoleate with ethylene was studied using a new temperature-dependent solvent system based on polyethylene glycol 1000. Under mild ethylene pressure, two hours' reaction at 80degreesC gave 95% conversion of conjugated methyl linoleate and 98% selectivity of cooligomers. By using this polyethylene glycol 1000 based temperature-dependent solvent system, an easy separation of product and catalyst phases has been achieved. (C) 2004 Elsevier B.V. All rights reserved.
