Beschreibung
Zusammenfassung:	The present invention relates to a method for producing resorcinol from meta-phenylenediamine using a non-corrosive catalyst, in which the internal pH is maintained basic by using FAU type zeolite as a catalyst, allowing the use of a reactor made of a general SUS material and providing an excellent manufacturing process with a yield of resorcinol of not less than 75%. 본 발명은 비부식성 촉매를 사용하여 메타-페닐렌디아민으로부터 레조르시놀을 제조하는 방법에 관한 것으로, FAU 타입의 제올라이트를 촉매로 사용함으로써 내부 pH가 염기성으로 유지되어 일반적인 SUS 재질의 반응기를 사용할 수 있고, 레조르시놀의 수율이 75% 이상으로 우수한 제조공정을 제공한다.
