Abstract
Densities and heat capacities of aqueous solutions of azoniaspiroalkane halides, (CH2) n N+ (CH2) n X− (where X=Cl, I andn=5,6), have been measured at 25°C using a flow densimeter and a flow microcalorimeter. The limiting apparent molal volumes (ø ∘v ) and apparent molal heat capacities (ø ∘cp ) obtained from these data are compared with those of the azoniaspiroalkane bromides and the corresponding tetraalkylammonium halides. The concentration dependence of ø v and øcp are examined for clues on the influence of solute hydration, structure, and conformational flexibility on the excess functions of quaternary ammonium halides.
