Abstract
(EN)
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).]
(FR)
L'invention concerne un nouveau moyen permettant de purifier un composé éther divinylique ayant un squelette d'alkylène pouvant être obtenu en utilisant moins d'énergie et d'une manière plus simple. Le procédé de production d'un composé éther divinylique comprend une étape A qui consiste à faire réagir un composé représenté par la formule (1) avec de l'acétylène à l'aide d'un catalyseur de métal alcalin et une étape B qui consiste à purifier le composé éther divinylique représenté par la formule (2), qui a été obtenu à l'étape A, sans effectuer d'extraction. [Dans la formule (1), R1 représente un groupe alkylène ayant de 4 à 20 atomes de carbone.] [dans la formule (2), R1 est le même que R1 dans la formule (1).]
