메틸 에틸 케톤 - 위키백과, 우리 모두의 백과사전
IUPAC 에서는 메틸 에틸 케톤이라는 이름을 더 이상 사용하지 않고 에틸 메틸 케톤 ( Ethyl Methyl Ketone , EMK )으로 사용할 것을 권장하나, 대한민국 정부 및 민간에서는 여전히 메틸 에틸 케톤이 주 명칭으로 사용되고 있다. 성상은 무색 투명하고, 달콤한 냄새를 풍기며, 상온에서 액체 로 있으나 휘발성이 강하고, 물에 약간의 용해성을 띈다. 산업용으로 대량 생산되지만 자연계에서는 미량만 …
The Dipole Moments of the Methyl and Ethyl Halides
The increase in moment from the methyl to the ethyl halide accords with the previously advanced hypothesis of an inductive effect, but the change in the increase with change in the halogen involved points to the influence of an additional factor. The change in moment from compound to compound is compared with the change in the Raman frequency…
