A catalyst for decomposition of 1,3-dioxanes, comprising calcium oxide, phosphorus pentoxide, chlorine, water and boron oxide, the ratio of the components as expressed in mass percent being as follows:

Catalyst for decomposition of 1,3-dioxanes

A method of processing high-boiling byproducts of isoprene production obtained at the first stage of isoprene production by the dioxane method into isoprene, isobutylene and formaldehyde which comprises the catalytic splitting of said products in the vapor phase in the presence of water with a weight ratio therebetween of 1:1/2, respectively, at 250-290.degree. C over aluminum oxide as catalyst. The resulting vapor mixture is catalytically split at 315.degree.-360.degree. C over calcium-phosphate catalyst with the formation of a reaction mixture containing isoprene, isobutylene and formaldehyde.
