The procedure described in Example 4 is followed, but instead of the propylene oxide solution 107 parts by volume/hour of a 50 percent strength by weight solution of ethylene oxide in methyl formate are used. In this example, only 40 parts by volume/hour of the methyl vinyl ether solution are employed. After working up as in Example 4, a mixture of 1,1,3,3-tetramethoxypropane, 2-(2',2'-dimethoxyethyl)-(1,3)-dioxolane, malondialdehyde bis-(ethyleneacetal), 1-methoxyethoxy-1,3,3-trimethoxypropane and 2-(2'-methoxy-2'-methoxyethoxy-ethyl)-(1,3)-dioxolane is obtained as the end product, the composition being as in Example 2.
