OPTIMIZATION OF TRANSPORT PROPERTIES FOR THE BINARY SYSTEM OF ACETONE– WATER AT 303.15-318.15 K BY RESPONSE SURFACE QUADRATIC MODEL

Transport properties of liquids and liquid mixtures are used to study the molecular interactions between the various components of the mixtures and also potential uses in an expansive scope of use territories, including environmental remediation, agriculture, bio film formation, quorum sensing, textile, pharmaceuticals, cosmetics, and the food, oil, and petrochemical industries and also transport properties plays a major role in momentum, heat, mass transfer operations and upstream-downstream processing. Optimization of Transport properties for the binary system of acetone– water at 303.15-318.15 K by response surface quadratic model. Response surface methodology (RSM) was employed to determine the optimum level of five transport properties of acetone-water mixtures (Densities, viscosities, ultrasonic velocity, refractive indices and surface tension).Central composite design of RSM was applied to study the five transport properties at six levels, and binary mixture (acetone-water) molecular interactions was measured as a response. Regression coefficients were calculated by regression analysis and the model equation was determined. R2 value for transport properties of acetone-water mixture was calculated as 99%, and it indicates that the model was well fitted with the experimental results. Surface plots were made, and the maximum transport properties of acetone-water mixtures (0.85g/cc,0.65m.Pa.s,1540 m/s,1.35 and 74.72 mN/m) was predicted at the optimized values of temperature 318.15K, and mole fraction 0.9. The obtained mathematical model was verified by performing the experiment with the predicted optimized values, and the yield of acetone-water mixture was found to be 8.69 g/L. Validation of the predicted model was fitted 86.9% with the experimental results conducted at the optimum conditions. Results of this statistical analysis showed that temperature and mole fraction had found significant optimum conditions for transport properties of acetone-water mixture.
