Claims (1)
- 이소부틸렌, 3급부틸알콜과 같은 메타크롤레인 전구물질 또는 메타크롤레인과 분자산소를 희석용 불활성가스 공존의 산화촉매 존재하에서 기상반응시키고, 수득된 기상반응 혼합물을 냉각하여 메타크릴산, 아세트산 및 수증기로 구성되는 응축액과 메타크롤레인 등으로 구성되는 비응축기상 혼합물로 분리하고, 응축액으로부터 혼입 메타크롤레인을 제거한 후 이 응축액을 유기용매와 접촉분리시켜 메타크릴산 함유유기용매 용액으로 메타크릴산을 제조하며 또 잔유 수용액을 폐수처리하는 메타크릴산 제조시의 폐수처리방법에 있어서, 질소, 이산화탄소, 이들의 수증기 혼합물 등의 비응축성 가스를 희석용 불활성가스로 사용하며, 또 잔유 폐수수용액을 증발시켜서 방출된 증기를 산화촉매 존재하에서 분자산소로서 연소시킴을 특징으로 하는 메타크릴산 제조시의 폐수처리방법.
