Liquid crystalline compound (S)-5-(2-methylbutoxy)-2-[[[4-hexylphenyl]imino]methyl]-phenol (MBHPIMP) has been prepared and characterized. Phase transition temperatures of MBHPIMP were determined by polarizing microscopy, differential scanning calorimetry and inverse gas chromatography. Trace amount of solvents such as methyl acetate, ethyl acetate, pentane, hexane, cyclopentane, cyclohexane were passed through the gas chromatography column loaded with MBHPIMP coated on Chromosorb W. MBHPIMP exhibits liquid crystal properties with calamitic molecular shape which has a chiral moiety and alkyl chain at the terminus. The retention diagrams of the solvents on the liquid crystal were plotted by means of specific retention volumes, 0 Vg at the temperatures in o C between 40 and 95 by inverse gas chromatography. The weight fraction activity coefficient, ∞ Ω1 , Flory-Huggins liquid crystal-solvent interaction parameter, ∞ 12 χ , equation of state liquid crystal-solvent interaction parameter, ∗ 12 χ and effective exchange energy parameter, Xeff related to the MBHPIMP-solvent systems were obtained. In addition, the partial molar heats of sorption, ΔH1,sorp and mixing, ∞ ΔH1 were determined.

Active accounts were imported to the new platform and assigned a random password by default. In order to access your account you need to access the login page and go through the Lost Password dialog (involves the system sending you an email with instructions) in order to reset your password. This step is necessary as passwords are kept in hashed form and the new platform uses modern hashing algorithms incompatible with the previous ones.
