PROCESS FOR REMOVING HYDROPEROXIDES AND ALDEHYDES FROM ALLYL-ALKYL ETHER ABSTRACT OF THE DISCLOSURE Described herein is a process for the conversion of hydroperoxides, present in allyl-alkyl ethers to products including .alpha.,.beta.-unsaturated aldehydes and for reducing such .alpha.,.beta.-unsaturated aldehydes to alcohols prior to the use of the ether as a feedstock in a hydroformylation reaction to produce the corresponding ether aldehyde. The process involves contacting the ether with a metal hydride, either in aqueous solution and/or by means of an ion exchange resin. Such treat- ment decomposes the hydroperoxides and then reduces their .alpha.,.beta.- unsaturated aldehyde decomposition products, thereby reducing the catalyst inhibition period present in the hydroformylation reaction which is observed when such .alpha.,.beta.-unsaturated aldehyde impurities are present.
