Abstract
The hydration of dodecyltrimethylammonium hydroxide (DTAOH) micelles w as determined by viscosity measurements, giving 39.2 +/- 7.0 water mol ecules per micellized dodecyltrimethylammonium ion. This result is low er than the hydration of DTAB micelles, which is about 65. This differ ence may be due to the effect of the electrorestrictive structure-maki ng hydroxide ion on the hydration of the alkyltrimethylammonium head g roup, in comparison with the less hydrated structure-breaking bromide ion.
