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.
鉴于甲基乙烯基醚可用作合成四烷氧基丙烷的起始原料,而四烷氧基丙烷可用作骨架形成剂,具有高反应活性,可用作医药和农用化学品中间体(如吡唑衍生物或嘧啶衍生物)的起始原料等。四烷氧基丙烷是医药和农用化学品的中间体,如吡唑衍生物或嘧啶衍生物,特别是 1,1,3,3 四甲氧基丙烷,呈气态,难以用于工业生产、而作为医药和农用化学品中间体(如吡唑衍生物或嘧啶衍生物)骨架形成剂的四烷氧基丙烷,使用工业上可用的丙氧基乙烯基醚作为起始原料,而不使用气态的甲基乙烯基醚,则很容易进行工业化生产。
