ABSTRACT:
Disclosed is a novel process for effecting an ether interchange reaction by heating together in the presence of a basic catalyst, a nitroaromatic ether or thioether and an organic compound containing at least one hydroxyl or mercapto group. The novelty resides particularly in carrying out the interchange in an inert solvent while sparging the heated reactants thereby to remove at least a portion of solvent along with an evolving alcohol or thiol.
The process is particularly adapted to the capping of organic polyols with nitroaromatic ether groups. The capped products are useful as intermediates for the preparation of high molecular weight polyamines which in turn find utility in various polymer applications.
