The formation of the ground state charge transfer complex between durene and chloranil has been investigated in CH2Cl2 and in microemulsions. The CH2Cl2 or CH2Cl2/hexadecane microemulsion systems in water are stabilized by a cationic (hexadecyltrimethylammonium bromide) surfactant and 1-butanol as cosurfactant; the droplets have an average radius of 3.5 ± 0.5 nm. If the effective concentration in the oil phase (CH2Cl2 or CH2Cl2/hexadecane) is accounted for, the equilibrium constant is not significantly changed with respect to the homogeneous CH2Cl2 solution. The equilibrium of formation or dissociation of the complex is reached in less than 1 × 10−3 s.

Abstract
The formation of the ground state charge transfer complex between durene and chloranil has been investigated in CH2Cl2 and in microemulsions. The CH2Cl2 or CH2Cl2/hexadecane microemulsion systems in water are stabilized by a cationic (hexadecyltrimethylammonium bromide) surfactant and 1-butanol as cosurfactant; the droplets have an average radius of 3.5 ± 0.5 nm. If the effective concentration in the oil phase (CH2Cl2 or CH2Cl2/hexadecane) is accounted for, the equilibrium constant is not significantly changed with respect to the homogeneous CH2Cl2 solution. The equilibrium of formation or dissociation of the complex is reached in less than 1 × 10−3 s.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
