Solvodynamics of Benzene and Water Phases by DTAB, MTOAC, TMSOI and Orcinol Studied with Interfacial Tension, Surface Tension and Viscosity Measured with Survismeter

Both benzene and water immiscible phases when mixed together develop an energetic interface that remains tense due to individual surface tensions. Physics of a tense interface does equilibrate tensional forces to have an optimized surface force which is denoted as Interfacial Tension (IFT, mN/m). The IFT between water and benzene with addition of surfactants: dodecyltrimethylammonium bromide (DTAB), trimethylsulfoxonium iodide (TMSOI), methyltrioctylammonium chloride (MTOAC) and 3,5-dihydroxytoluene monohydrate (Orcinol) critically decrease to 15.69, 12.86, 10.59, 8.36, 2.97 mN/m for DTAB , TMSOI, water, orcinol, MTOAC respectively. This lowering of IFT infers a higher mutual miscibility (MM) of the phases denoted as wetting. The DTAB and orcinol increased surface tension of water from 71.25 to 79.55 and 72.70 mN/m respectively at 304.65 Kelvin temperature due to stronger cohesive forces.
