수증기 증류법을 사용해 향기 성분을 분리한다.


분리 방법: 수증기 증류

🛢️ 3. 석유의 분별 증류


혼합물: 석유(다양한 탄화수소 혼합물)


원리: 각 탄화수소의 끓는점 차이를 이용하여 여러 온도 구간에서 증류


결과:


20~70 °C → 휘발유(gasoline)


150~250 °C → 등유(kerosene)


250~350 °C → 경유(diesel)


350 °C 이상 → 중유, 아스팔트 등

➡️ 응용: 석유 정제 공정

바닷물은 물과 소금이 섞여 있는데, 물은 끓는점이 100℃, 소금은 훨씬 더 높아.

그래서 바닷물을 끓이면 물만 먼저 수증기가 되고, 소금은 남아 있어.

이 수증기를 다시 차갑게 식히면 다시 물이 되기 때문에,

바닷물에서 순수한 물을 얻을 수 있다. → 이게 증류야.

과정: 혼합물을 가열하면 에탄올이 먼저 기화되고, 이를 냉각시켜 다시 액체로 모으면 에탄올을 분리할 수 있습니다.

활용:술의종류
