Title:
METHOD FOR PRODUCING DIVINYL ETHER COMPOUND HAVING ALKYLENE SKELETON
Document Type and Number:
WIPO Patent Application WO/2020/111031
Kind Code:
A1
Abstract:
Provided is a new means by which purification of a divinyl ether compound having an alkylene skeleton can be achieved using less energy and in a simpler manner. This method for producing a divinyl ether compound includes a step A for reacting a compound represented by formula (1) with acetylene using an alkali metal catalyst and a step B for purifying the a divinyl ether compound represented by formula (2), which was obtained in step A, without carrying out extraction. [In formula (1), R1 denotes an alkylene group having 4-20 carbon atoms.] [In formula (2), R1 is defined the same as R1
in formula (1).]
