Title (EN) METHOD FOR PREPARING XYLYLENEDIAMINE
(FR) PROCÉDÉ DE PRÉPARATION DE XYLYLÈNEDIAMINE
(KO) 크실릴렌디아민의 제조방법
Abstract: front page image
(EN)The present invention relates to a method for preparing xylylenediamine from xylene, the economical and eco-friendly method comprising: cooling a reaction-produced gas produced from an ammoxidation reaction in order to selectively deposit phthalonitrile; and easily collecting unreacted xylene, tolunitrile, and ammonia and reusing same as reacting raw materials, thereby improving process yield.
(FR)La présente invention concerne un procédé de préparation de xylylènediamine à partir de xylène, ledit procédé, économique et respectueux de l'environnement, comprenant les étapes consistant à refroidir un gaz de réaction produit par une réaction d'ammoxydation afin d'obtenir, de manière sélective, le dépôt du phtalonitrile, et à récupérer facilement le xylène, le tolunitrile et l'ammoniac n'ayant pas réagi pour les réutiliser en tant que matières premières de réaction, ce qui permet d'améliorer le rendement du procédé.
(KO)본 발명은 크실렌으로부터 크실릴렌디아민을 제조하는 방법에 있어서, 가암모니아 산화반응에 의해 생성된 반응생성가스를 냉각하여 프탈로니트릴을 선택적으로 석출하고, 미반응 크실렌, 톨루니트릴 및 암모니아를 쉽게 회수하여 반응원료로 재사용함으로써 공정수율을 향상시킨, 경제적이고 친환경적인 크실릴렌디아민의 제조방법에 관한 것이다.
