Description

technical field

[0001] The invention relates to a new synthesis process of 2-alkoxypropene. Background technique

[0002] 2-Alkoxypropene is an important pharmaceutical and chemical raw material. Because it has both double bonds and ether bonds, its chemical properties are very active. It is often used as a solvent and auxiliary agent in the paint, textile and leather industries, and also as a key intermediate in the synthesis of medicine, food and feed. Among them, 2-methoxypropene is the most important and widely used alkenyl ether compound, which is used for the synthesis of clarithromycin, pseudoionone, ionone, isophytol, vitamin A, vitamin E, vitamin K2 and other medicines. It is a key intermediate of chemical, chemical and feed products, and has very important uses in industrial production.

[0003] There are two methods for synthesizing 2-alkoxypropene: alkyne alcohol condensation and ketal cracking. Among them, the aldol condensatio...
