早在1886年Mylius在研究氢醌及几种挥发性化合物时发现一种不寻常的复合物,在这种复合物中,不能用嗅觉检测挥发性物质,只有在加热或溶于水时,才能嗅到挥发性物质,因而设想这是由于氢醌分子包围了挥发物的缘故。许多年之后,这一设想被X-射线衍射分析所证实,并测知约有三分子的氢醌与大约一分子的气体或液体挥发物形成不溶性包含物。这种类 As early as 1886 Mylius in the study of hydroquinone and several volatile compounds found in an unusual complex, in which complex, can not smell the detection of volatile substances, only when heated or dissolved in water to Smell volatile substances, so imagine this is due to hydroquinone molecules surrounded the volatile sake. Many years later, this idea was confirmed by X-ray diffraction analysis and found that about three molecules of hydroquinone form about one molecule of gaseous or liquid volatiles that form insoluble inclusions.
