To utilize Cu-benzene-1,3,5-tricarboxylate(Cu-BTC)adsorbed lubricant oils in the self-lubricating field,the adsorption properties of Cu-BTC on different 1-olefins must be clarified.In this work,1-hexene,1-octene,1-nonene,1-decene,1-undecene,and 1-dodecene were studied by the Monte Carlo method and experimentally.The adsorption limit of Cu-BTC for n-olefins was determined as 1-undecene by the adsorption isotherms.This suggested a limit for even straight-chain molecules to the adsorption of Cu-BTC.The maximum ratio of the olefin length of the largest pore diameter(L/D)of Cu-BTC was approximately 1.57.Furthermore,theoretical calculations(radial distribution function(RDF))and experiments(infrared(IR)spectra)confirmed the interaction of n-olefin adsorbates and the Cu-BTC framework occurred between the-CH= of olefins and the Cu and O atoms of the Cu-BTC framework.This work adds to the understanding and investigation of the adsorption of liquid lubricants using Cu-BTC as a metal-organic framework(MOF).
