Abstract
본 발명에 따르면, 팽윤성 있는 탄화수소 흡수재와 외부 자극에 의해 색 전이 또는 형광을 나타내는 물질을 이용함으로써 고가의 복잡한 장비 없이 어디에서나 쉽게 육안으로 탄화수소를 식별할 수 있다. 또한 식별이 어려운 포화탄화수소의 구조 이성질체도 용이하게 식별할 수 있다. 특히 본 발명에 따르면, 석유제품 중 비슷한 특성을 보이는 등유와 경유의 식별을 위하여 현재 사용되는 식별제를 첨가하는 방법이나 접근이 어려운 복잡한 분석방법과 달리, 언제 어디에서나 손쉽게 등유와 경유를 육안으로 식별할 수 있어 사회적으로 문제되는 유사경유의 검출이 가능하다. 또한 본 발명에 따르면, 고가의 복잡한 장비 없이 간단한 방법으로 탄화수소의 육안 식별이 가능하여 일반인도 쉽게 사용할 수 있다.
