PHYSICO CHEMICAL STUDIES ON SOAP NUT [SAPINDUS TRIFOLIATUS] OIL FOR SOURCE AS BIODIESEL
Sapindus trifoliatus is a small tree belongs to the family Sapindaceae. Soap nut powder is a very good antibacterial and antifungal agent. It is mostly used in the cosmetic and contraceptive creams.It has a number of health benefits besides the famous benefit of keeping the hair long and healthy. It is useful in the treatment of lice's and dandruff. It is also used as detergent, bio-surfactant and remedial for organic soil pollution in the modern science. In this present study .The Physico- Chemical Properties of the Soap nut oil was analyzed by blending with conventional diesel at 10% (B10) and 20% (B20) proportions. The properties assessed in the physical parameters include, pH, Density Salinity, Viscosity, Specific gravity, Conductivity, Total dissolved oxygen and Total dissolved solid. The significant biodiesel characters likeÂ Â flash point, fire point, smoke point, pour point, cloud point and carbon residue were analysed. The ultrasonic characters like ultrasonic velocity, adiabatic compressibility, acoustic impedance, relaxation time were also assessed. The chemical parameters estimated such as Acid value, Iodine value and Saponification value. The values of the parameters were compared with the ASTMT standards of biodiesel. The biodiesel blend B20 is found to be within the ASTM standard and it can serve as a potential source for biodiesel.
