Claims (4)
- 초산 용매 중에서 초산코발트 및 초산망간 촉매 존재하에 p-크실렌을 산화시켜 테레프탈산을 제조함에 있어서, 그 반응 용액으로부터 공지의 방법으로 테레프탈산, 반응모액 및 용매를 분리한 반응폐액의 고형분에 대한 함수율을 25∼40%로 조정하여 800∼850℃에서 안전 소각 산화시켜 얻은 회분을 물 및 98% 초산의 혼합 용망에 용해한 다음 5∼35% 과산화수소와 반응시키는 제1공정과 이 반응액으로부터 미반응 물질을 제거하는 제2공정의 결합으로 구성된 것이 특징인 테레프탈산 제조촉매의 회수 방법.
- 제1항에 있어서, 물의 첨가량을 최종 초산의 농도가 5∼40%로 유지되는 양으로 하는 것이 특징인 방법.
- 제1항에 있어서, 초산과 과산화수소의 첨가비가 1 : 1 내지 10 : 1인 것이 특징인 방법.
- 제1항에 있어서, 제1공정을 30∼80℃ 근처에서 수행하는 것이 특징인 방법.※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.
