The association of 1-octadecanoic acid (C18) in 1, 2-dichloroethane at 40°C has been investigated by measuring the fluorescence spectra and intensities of ammonium 8-anilino-1-naphthalenesulfonate as a probe.As a result, it has been found that C18 begins to associate at a concentration of 1.0-1.2×10-2 mol·dm-3 and that the aggregation number is small and constant in the concentration region above about 4×10-2mol·dm-3.The mechanism for the formation of fatty acid (FA)-thiamine disulfide (TDS) complexes, (FA)6(TDS), was also discussed.
