Excess adsorption of cyclohexanone, cyclohexanol and tert-butanol over metal–organic frameworks Cr-MIL-100 and structurally close Cr-MIL-101 from n-hexane was measured at room temperature. Apparent adsorption equilibrium constants were calculated under the assumption of monolayer adsorption. Two types of adsorption centers turned out to be enough to build a model of experimental isotherms for cyclohexanone, cyclohexanol, and tert-butanol. The first type of centers is characterized by a high value of adsorption equilibrium constant, 1 × 10³–3 × 10³, and the fraction of such centers is ca. 0.2 for cyclohexanone and tert-butanol and ca. 0.4 for cyclohexanol. The second type of centers possesses a relatively low affinity to guest molecules (the adsorption equilibrium constant varies from 1.8 to 9) and occupies the rest of the surface of the adsorbent The centers with a strong affinity to oxygen-containing guests are associated with chromium atoms within MIL framework.

过量吸附的环己酮，环己醇和叔丁醇在金属-有机骨架的Cr-MIL-100和结构上接近的Cr-MIL-101从ñ -己烷在室温下测量。在单层吸附的假设下计算表观吸附平衡常数。事实证明，两种类型的吸附中心足以为环己酮，环己醇和叔丁醇建立实验等温线模型。第一种类型的中心的特征在于，其吸附平衡常数值较高，为1×10 ³ –3×10 ³，而这些中心的分数约为ca。环己酮和叔胺为0.2-丁醇和。环己醇为0.4。第二类中心对客体分子的亲和力相对较低（吸附平衡常数在1.8到9之间变化），并占据了吸附剂表面的其余部分。对含氧客体具有强亲和力的中心与铬原子有关在MIL框架内。
