摘　　要：丁酮肟由于其低毒、低污染和高脱氧效果而被用作防结皮剂、锅炉的除氧剂和脱酮肟基硅烷交联剂的生产原料,然而丁酮肟及其二元混合体系的密度与黏度却鲜有报道。本文利用密度瓶,测定了丁酮肟-丁酮、丁酮肟-环己烷和丁酮肟-正己烷三个二元体系在(293.15～303.15)K、常压条件下的密度,用乌氏黏度计测定了三个二元混合体系在(293.15～303.15)K、常压条件下的黏度。对不同温度下混合密度与组成的关系,通过多项式方程进行了拟合;对不同温度下混合黏度与组成的关系,分别通过Grunberg-Nissan和Eyring-UNIQUAC方程进行了拟合,并给出了回归系数和平均相对偏差。本文数据和关联可为丁酮肟相关工业过程的设计、模拟和优化提供便利。Methyl ethyl ketoxime can be used as an anti-skinning agent,passivator in boiler passivation solution and raw material for producing deketoximized curing agent due to its low toxicity,low environmental pollution and high deoxidization effect.However,densities and viscosities of methyl ethyl ketoxime and its binary mixtures have been rarely reported.In this work,densities and viscosities of methyl ethyl ketoxime with methyl ethyl ketone,cyclohexane and n-hexane were measured over the entire range of composition at T =（293.15,298.15 and 303.15） K and atmospheric pressure by using Gay-Lussac pycnometer and Ubbelohde viscometer,respectively.The densities were fitted by a polynomial equation,while viscosities were correlated by the Grunberg-Nissan equation and Eyring-UNIQUAC equation.The parameters and average absolute deviations at different temperatures were given.The densities and viscosities in this work will be beneficial for the design,simulation,and optimization of relative industrial processes containing methyl ethyl ketoxime.
