Abstract:
In view of the fact that a methyl vinyl ether, which is useful as a starting material for the synthesis of tetraalkoxypropane useful as a skeleton-forming agent having a high reactivity usable as a starting material, etc. for a pharmaceutical and agrochemical intermediates such as a pyrazole derivative or pyrimidine derivative, particularly 1,1,3,3-tetramethoxypropane, is in a gaseous state and difficult to use for industrial production, tetraalkoxypropane useful as a skeleton-forming agent for a pharmaceutical and agrochemical intermediate such as a pyrazole derivative or pyrimidine derivative is easily produced on an industrial scale by using the industrially useable propoxyvinyl ether, as a starting material, without using a gaseous state methyl vinyl ether.
