3-Hydroxy-substituted carbonyl compounds are produced by the reaction of 2-hydrocarbonoxyoxetanes with water. Hydrocarbonoxyoxetane mixtures such as mixtures consisting essentially of 2-alkoxyoxetanes and 3-alkoxyoxetanes which can be made by the ultraviolet light-induced reaction of an aldehyde or ketone with a vinyl ether also can be employed as the 2-hydrocarbonoxyoxetane. The 3-hydroxy-substituted carbonyl compounds made by the aforesaid method can be employed as plasticizers for polyvinylchloride resins, cosolvents for aqueous polyvinyl alcohol, or maleic anhydride vinyl ether copolymer mixtures, etc. The 3-hydroxy-substituted carbonyl compounds also are intermediates for making alpha , beta -unsaturated aldehydes and ketones which include useful intermediates for making vitamin A and polymers.
