| Abstract: | A saponification and membrane extraction method for preparation of neodymium naphthenate at room temperature is put forward.Factors influencing the process and reaction mechanism were studied.By saponified extraction process,not only the utilization rate of neodymium ion can be increased,but also free acid content can be controlled discretionarily.And with the membrane extraction process,water in neodymium naphthenate can be decreased.The saponification and membrane extraction process is a combination of the above processes.The product has good catalytic property for the formation of diene stereospecific polymers. |
