Abstract

Preferential 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+CH2Cl2 and AC+CCl4 mixtures. DMMAD prefers PROH in PROH+CCl4 mixture. In the case of benzene+CCl4 mixture DMMAD is preferentially solvated by benzene in benzene rich region and by CCl4 in CCl4 rich region. The results have been discussed in terms of hydrogen bonding, dipole-dipole and induced dipole-dipole interactions between DMMAD and solvent molecules.
