The theoretcal values of ultrasonc velocty of the bnary mxture have been calculated usng several theoretcal models such as s relaton (N), Impedance dependence relaton () and Danuusso model (D). Theoretcal values of ultrasonc velocty were compared wth expermental values and the relatve merts of these models were dscussed. Keywords: DEHPA, Bnary mxtures, ltrasonc velocty, Theoretcal models of ultrasonc velocty. I. INTRODCTION ltrasonc nvestgaton s one of the sgnfcant technques used for studyng the nature as well as degree of molecular nteracton between the lke and unlke molecules of the components n varous polar/apolar lqud mxtures, nvestgated by several researchers [1-4]. The study nfers the physcochemcal behavour of lqud mxtures whch s useful n the feld of petrochemcal, pharmaceutcal and nuclear energy ndustres. The ultrasonc veloctes for all bnary mxtures were evaluated theoretcally as a functon of composton usng s relaton, Impedance dependence relaton and model [5-8]. II. EXPERIMENTAL SECTION All the chemcals used n ths nvestgaton are of Analytcal Reagent grade and were obtaned from E- Merck Chemcals Ltd. Inda. These chemcals were used wthout further purfcaton. Our procedures of measurements have been descrbed earler [9]. III. RESLTS AND DISCSSIONS The values of ultrasonc veloctes, of pure d (2- ethyl hexyl) phosphorc acd (DEHPA) and three monocarboxylc acds vz. acetc acd, proponc acd and n-butyrc acd and ther bnary mxtures wth DEHPA as a common component were measured expermentally at K under atmospherc pressure. The expermental value of ultrasonc veloctes n lqud mxtures were compared wth those values calculated usng varous theoretcal models, vz. s relaton, Impedance dependence relaton and model [5-8, 10] and are presented n Table 1. Such an evaluaton offers a smple method to nvestgate molecular nteractons besdes verfyng the applcablty of varous propertes of lqud mxtures [5-8, 10]. sng the respectve models, ultrasonc velocty such as N, and D were estmated (Table 1) by the followng relatons and models as gven by x R x V 3 (1) N x Z x (2) D m M eff x M where x,, ρ, Z, (3) R V m 1/ 3, V m and M are mole fracton, ultrasonc velocty, densty, acoustc mpedance, molecular sound velocty, molar volume and molecular weght of th component of the mxture respectvely and M eff = x M s the effectve molecular weght of the mxture. The root mean square devaton relatve (RMSD) between the ISSN: Page 304
2 expermental and theoretcal values of ultrasonc velocty was calculated. The value of RMSD s used to estmate the relatve merts of the theoretcal relatons exp ) exp RMSD = ( 1 ) ( p th (4) where p s the number of expermental data ponts. TABLE I Expermental and theoretcal values of ultrasonc velocty (SI nt) of bnary mxtures of acetc acd, proponc acd and n-butyrc acd wth DEHPA ( ) Mole fracton Expt N D acetc acd + DEHPA proponc acd + DEHPA ISSN: Page 305
3 n-butyrc acd + DEHPA In our earler study [10], the theoretcal results of ultrasonc velocty n bnary mxtures of MIBK wth DEHPA betokens that s relaton s more sutable n favour of expermental values of ultrasonc velocty. So s relaton makes accurate predcton of the ultrasonc velocty n that synergstc mxture havng hgher molecular volumes. In ths present work, we have the smlar analyss on another bnary mxtures of one extractant (DEHPA) + monocarboxylc acds over entre mole fracton range of DEHPA. The values of root mean square devaton are presented n Table 2 and the values are found low n all cases under study. ISSN: Page 306

IV. CONCLSION Several theoretcal models have been correlated wth the expermental data of ultrasonc velocty and the relatve applcablty were studed n all bnary systems under nvestgaton. Theoretcal results of ultrasonc velocty such as N, and D n bnary mxtures of acds wth DEHPA nfers that model s more sutable n favour of expermental values of ultrasonc velocty. Thus, model makes accurate predcton of the ultrasonc velocty n the studed bnary mxtures.
