STUDY OF HYDROCARBON CHAIN LENGTH ON VISCOSITY BEHAVIOR OF TETRA BUTYL AMMONIUM BROMIDE SOLUTIONS IN DIFFERENT TEMPERATURES

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
