Abstract
Description
도 2는 톨루엔 메틸화 구역이 통합되어 있는 아로마틱 콤플렉스의 다른 실시양태를 도시한 것이다.
도 3은 톨루엔 메틸화 구역이 통합되어 있는 아로마틱 콤플렉스의 또 다른 실시양태를 도시한 것이다.
도 4는 톨루엔 메틸화 구역이 통합되어 있는 아로마틱 콤플렉스의 다른 실시양태를 도시한 것이다.
몇몇 도면을 통해 상응하는 도면 부호는 상응하는 부품을 지시한다. 당업자라면 도면의 요소들은 간단하고 간결하게 도시된 것이고 반드시 실제 척도로 도시된 것이 아님을 이해할 것이다. 예컨대, 본 개시내용의 여러 실시양태들의 이해 증진을 돕기 위하여 도면에서 일부 요소들의 치수는 다른 요소들에 비해 과장되어 있을 수 있다. 또한, 상업적으로 실행가능한 실시양태에 유용하거나 필요한 통상적이고 잘 알려진 요소들은 본 개시내용의 여러 실시양태들의 도시가 덜 방해되도록 흔히 도시되지 않는다.
