Influence Of Reason C T And Salinity In Aqueous Phase With Microemulsion Systems Ocs-Butanol-Water-Kerosene

This work aims to study the best region of microemulsion by calculating the integral area by varying some parameters. We used a saponified coconut oil (OCS) as surfactant, cosurfactant butanol, kerosene as a nonpolar component, water or brine (2% KCl) as polar component. The binodal curves were determined by clouding point titration method. The composition of the mixture for each point on the binodal curve was determined from the amount of titrant added until turbidity was observed using an analytical balance. We studied the influence of the ratio cosurfactant/surfactant(C/T) and salinity by varying these parameters. Prioritizing the microemulsion region, it was found that for the system with water, the increase of the ratio C/T region extends microemulsion. The system showed the best area in this case was the water-kerosene-butanol/OCS=3. For a system with brine, it was found that increasing the salinity decreased the microemulsion region for a given ratio C/T fixed. The systems that best presented area in this case were the systems kerosene-butanol/ OCS=2/2% KCl and kerosene-butanol/OCS=3/2% KCl. For systems in which there was a variation in the salinity and the ratio C/T, it was found that increasing the ratio C/T associated with decreased variation in salinity of the microemulsion region (kerosene-butanol/OCS=2/2% KCl).
