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 treatment decomposes the hydroperoxides and then reduces their .alpha..beta.unsaturated aldehyde decomposition products thereby reducing, the catalyst inhibition period present in the hydroformylation reaction …
