Method for improving the extraction properties of a tributyl phosphate solution

Description

Improvements to the Purex process are described, comprising contacting tributyl phosphate solution containing degradation products with a solution of diazomethane whereby the degradation products of tributyl phosphate are esterified to triesters having improved extraction properties. Thus a method has been developed which is relatively inexpensive, free from interfering by-products and side reactions and by which the extraction system is restored to almost its original efficiency. In addition, by this method, expensive cleanup procedures are eliminated and the use-life of the extraction solution is greatly prolonged
