摘要：
The state of disperse anthraquinone dyes in aqueous and aqueous salt solution has been studied by spectrophotometry. From the experimental data the association numbers of the dyes have been calculated. There is a relation between the molecular structure of the organic nonelectrolytes, and their tendency to undergo associative interaction in water. Dyes show different tendencies to association in aqueous solution; these are characterized by similar changes in the enthalpy of hydration. We have studied the effect of structure of the state of nonionic dyes in water. A hydroxyl derivative of anthraquinone forms a complex with Al3+ in water.
