Reaction of linear acetals RCH(OR′)2 (R = H, CH3, C2H5; R′ = CH3, C2H5, C3H7) with ethylene glycol in a neutral medium at 25°C was studied by 13C NMR spectroscopy. The equilibrium compositions of the reaction mixtures and their dependence on the reactant molar ratio were determined. It is shown that under the experimental conditions used dimethoxymethane fails to react with ethylene glycol, and the reactions of the other acetals yield much cyclic acetals, 1,3-dioxolanes. The reaction of 2-methyl-1,3-dioxolane with methanol gives the same products as the reaction of 1,1-dimethoxyethane with ethylene glycol.
