## Abstract **Summary:** Cellulose alkyl esters such as ethyl, butyryl, pentyl, and heptyl cellulose with different numbers of carbon in the alkyl ester group were synthesized for the separation of a mixture of benzene/cyclohexane (Bz/Chxβ=β5/95 w/w) with a low concentration of benzene. All of cell
The side-chain liquid-crystalline polymer (LCP) was synthesized by the addition of the mesogenic monomer to poly (methylsiloxane) with Pt catalyst. When the benzene/cyclohexane mixtures were permeated through the LCP membranes by pervaporation at various temperatures, the permeation rate increased w
Membranes prepared from carboxylated polysulfone permeated benzene preferentially from benzene-cyclohexane mixtures by pervaporation. Hydrophilic polysulfones containing carboxyl groups with degrees of substitution (DS) ranging from 0.46 to 1.90 groups per repeating unit were selected for this study
