Investigations of preferential solvation on 1,4-dimethoxy-3-methyl anthracene-9,10-dione

International audiencePreferential solvation of 1,4-dimethoxy-3-methyl anthracene-9,10-dione (DMMAD) has been investigated using optical absorption technique. The preferential solvation parameters show that the DMMAD is preferentially solvated by acetone in acetone (AC) + propan-2-ol (PROH), AC + CH(2)Cl(2) and AC + CCl(4) mixtures. DMMAD prefers PROH in PROH + CCl(4) mixture. In the case of benzene + CCl(4) mixture DMMAD is preferentially solvated by benzene in benzene rich region and by CCl(4) in CCl(4) rich region. The results have been discussed in terms of hydrogen bonding, dipole-dipole and induced dipole-dipole interactions between DMMAD and solvent molecules. (C) 2010 Elsevier B.V. All rights reserved
