Abstract
This research is concerned with viscosity and density measurements at concentration range
(0.0042 – 0.1241) mol/l for the tetra butyl ammonium bromide ( TBABr) solution in ethanol at temperatures (
298.15 , 303.15 and 308.15 ) K0 and for ( TBABr) in (1- butanal , 1- hexanol ) at 298.15 K0 . The viscosity ( B
) coefficient was calculated from Jones-Dole equation and found to have small value. While (B) values are
increased with the increasing of chain length of hydrocarbon chain length for alcohols (1- butanal , 1- hexanol).
From these results the tetra butyl ammonium bromide ion (C4H9)4N+ appear to be structure maker for the selfassociation
alcohol structure.This reinforced phenomenon found to be related with the ability of alcohols to form
hydrogen bonding clatharate around the ammonium ion
