Sl. David et Kumar S",kabiruddin, VISCOSITIES OF CETYLPYRIDINIUM BROMIDE SOLUTIONS (AQUEOUS AND AQUEOUSKBR) IN THE PRESENCE OF ALCOHOLS AND AMINES, Journal of chemical and engineering data, 42(1), 1997, pp. 198-201
The effect of organic additives (aliphatic/aromatic amines or alcohols
) on the viscosities of aqueous and 0.1 M KBr solutions of 0.05 or 0.1
M cetylpyridinium bromide have been measured under Newtonian flow con
ditions. The viscosity changed dramatically in the presence of KBr. Th
is is explained by the favorable conditions produced by the salt which
assists the micellar growth by organic additives with a concomitant e
nhancement in viscosity. Reasons for the effectiveness of these additi
ves are suggested. The causes of the viscosity decrease at higher conc
entrations of the additive are also explained.
