ABSTRACT:
Disclosed herein is a method which provides substantially zero acid number polytetramethylene ether glycol thus making it possible to regard polytetramethylene ether glycol as a fungible commodity. The improvement is achieved by complete removal of a trace impurity, believed to be n-butyl aldehyde, from dry tetrahydrofuran, by contact with molecular sieves of a particular definition, prior to the polymerization of the tetrahydrofuran in the production of polytetramethylene ether glycol.
