Solubilization Using Some Novel N-Methyl Diethanolammonium B

ABSTRACT
A novel series of N-methyl diethanolammonium bromide cationic
surfactants was used as solubilizing agent for nonpolar substrate (paraffin oil)
at 25oC. The results of solubilization measurements showed good ability for
the used surfactants towards solubilizing paraffin oil in aqueous medium. The
results showed also, that the chemical structure of the solubilizate plays an
important rule in its solubilization. Several factors were found to influence the
extent of solubilization, which are: number of alkyl chains within surfactant
molecule, symmetry of molecules and chain length of hydrophobic parts. The
results were rationalized by the Kraft point and HLB values of the used
surfactants. Furthermore, solubilization curves showed the steady state
solubilization of each surfactant used.
