Abstract EN
This paper reports on the viscosity and density study of the 1, 4, 7, 10, 13pentaox-cyclopentadecane (15C5) as binary system and 15C5 in present of KBr (the ternary system) in aqueous solutions at 25oC.
The results of the viscosity7 and density depends on ty pe of system, and concentration rang.
The relative viscosity obtain was fitted well by the use of Jones-Dole and Falkenhagen equations to the viscosity parameters i.e.
the apparent molar volume and the effective rigid molar volume at infinite dilution.
The results indicate that 4.2 mole of water are encaged in one mole of I5C5 and the complexation volume 0.015 dm3mol-l K+ with 15C5 has been determine.
.
The results are interpreted in terms of molecular and occupation of crow n ether cavity by solvent molecules.
