ABSTRACT:
It has been surprisingly discovered in accordance with the present invention that when 1,3-dioxolane is reacted with formaldehyde in the presence of an organic peroxide, the reaction preferentially involves an addition of the formaldehyde to the 2-methylene group of the 1,3-dioxolane with only minor reaction with the 4-methylene and 5-methylene groups of the 1,3-dioxolane whereby the reaction product that is formed contains significant quantities of 2-hydroxymethyl-1,3-dioxolane. 2-Hydroxymethyl-1,3-dioxolane is hydrolyzed with comparative ease to ethylene glycol and the corresponding glycol aldehyde (CHO--CH.sub.2 --OH). The glycol aldehyde in turn can be catalytically hydrogenated to form additional quantities of ethylene glycol.
