Abstract
This invention is concerned with producing ethylene and/or 1,2-propylene glycol by the reaction of a non-cyclic oxymethylene compound formed by the hydration or acetalization of formaldehyde with a compound containing one or more of silicon, germanium and tin bonded therein which functions as an addend in a photochemically or thermally induced radical reaction, to form a 1,2-dioxyethylene containing compound, and cleaving such 1,2-dioxyethylene containing compound to form the glycol thereof.
