Abstract:The effect of alcohol on microemulsions composed of Triton X-100,cyclohexane,co-surfactant and water was studied by means of emulsion breaking temperature,size distribution of nanosized silica,and TEM determination.It was found that interfacial film strength is closely related to the alcohol chain length,and branched isomers.In particular,the chain length of 1-octanol matches well with that of TX-100,so its interfacial film strength was highest,leading to the most number of micelle and optimum dispersion for preparing nanosized silica.For other alcohols,the chain length of(1-dodecanol) exceeded the effective length of TX-100 the most,so its interfacial film strength was minimum,(resulting) in the worst dispersion of nanosized silica.Branched alcohol isomers formed U system easily,resulting in the decrease of the number of micelle and(agglomeration) of nanosized silica.
Keywords:chain length  Triton X-100  W/O microemulsion  nanosized silica  micell number
