ABSTRACT: Densities and speeds of sound for the binary liquid mixtures of propylene glycol monomethyl ether (1-methoxy-2-propanol), CH3OCH2CH2CH2OH, propylene glycol monoethyl ether (1-ethoxy-2-propanol), C2H5OCH2CH2CH2OH, propylene glycol monopropyl ether (1-propoxy-2-propanol), C3H7OCH2CH2CH2OH, and propylene glycol monobutyl ether (1-butoxy-2-propanol), C4H9OCH2CH2CH2OH, with n-alkyl acetate over the whole composition range have been measured using an Anton Paar DSA 5000 M densimeter at T = (288.15, 293.15, 298.15, 303.15, and 308.15) K and atmospheric pressure. Experimental data on density and speeds of sound have been used to derive excess quantities like excess molar volume, VEm, and deviation in isentropic compressibility, ΔκS. The results have been discussed in terms of intermolecular interactions and their dependence on the composition and temperature.

INTRODUCTION When two liquids of different chemical properties are mixed together, it results into a state which has properties widely different from the constituent liquids. Understanding such behavior, in particular, the molecular interaction present between the pure liquids and solutions, becomes a necessity as they find a variety of applications in industries. The study of alkoxypropanols is important because they are widely used as solubilizing agents in many industries as well as in pharmaceutical and plastic products. Esters are important because they have distinctive flavor and pleasing odor due to which they are widely used in flavor and fragrance industries and also used as plasticizers to get specific thermoplastic characteristics.1,2 The study of mixing behavior of mixtures containing alkoxypropanols and esters is useful for many industrial applications. A literature survey reveals that the thermophysical behavior of binary mixtures of esters with glycols,3,4 n-alkanols,5−12 acetonitrile,13 acrylonitrile,14 hydrocarbons,15−17 chloroalkanols,18,19 and fatty acids20 have been extensively studied. In literature, there also exist thermodynamic properties of esters with polyethers.21−23 Systematic thermodynamic measurements on binary liquid mixtures comprising of alkoxypropanols + alkanols24−28 have been carried out in our laboratory. The scarcity of data on the molecular interactions existing between n-alkoxypropanols and n-alkyl acetates in terms of density and speed of sound incited us to start our investigation. This study was carried out to understand the intermolecular interactions present between alkoxypropanols and esters. In this study, densities and speeds of sound of the binary liquid mixtures of propylene glycol monomethyl ether (PGMME), propylene glycol monoethyl ether (PGMEE), propylene glycol monopropyl ether (PGMPE), and propylene glycol monobutyl ether (PGMBE) with n-alkyl esters comprising methyl acetate (MA), ethyl acetate (EA), and n-butyl © 2013 American Chemical Society
acetate (BA) using an Anton Paar DSA 5000 M densimeter at T = (288.15, 293.15, 298.15, 303.15, and 308.15) K and atmospheric pressure have been reported. Acoustic and thermodynamic parameters derived from experimental data have been used to understand behavioral patterns of liquids in a mixture affected by structural modifications.

EXPERIMENTAL SECTION
Materials. PGMME (Sigma Aldrich, Germany, mass fraction purity 0.98), PGMEE (Acros Organics, New Jersey, USA, mass fraction purity 0.90 to 0.95), PGMPE (Sigma Aldrich, Germany, mass fraction purity 0.985), PGMBE (Sigma Aldrich, Germany, mass fraction purity ≥ 0.99), MA (Merck-Schuchardt, Germany, zur synthese GC mass fraction purity > 0.99), EA (S. D. Fine-Chem Limited, Mumbai, GC mass fraction purity 0.995), and butyl acetate (SISCO Research laboratories Pvt. Ltd. Mumbai, GC mass fraction purity 0.99) were used as such. The chemicals were stored in tightly sealed dark bottles to keep the atmospheric moisture absorption to minimum. Further, the chemicals were vacuum degassed, and the moisture content was reduced with the help of molecular sieves. The densities and speeds of sound of pure chemicals were compared with literature values3,19,29−39 at reported temperatures. These values along with specification of chemicals are reported in Table 1. Apparatus and Procedure. All of the measurements on densities, ρ, and speeds of sound, c, were carried out on an Anton Paar DSA 5000 M densimeter. Calibration of the densimeter before carrying out experimental measurements was done with degassed Received: June 7, 2012 Accepted: December 19, 2012 Published: January 8, 2013 225

where n and m are the number of data points and parameters, respectively. Figures 1 and 2 show the experimental values of VEm and ΔκS only at 298.15 K as the curves are similar in nature at other temperatures. The values of VEm and ΔκS are all positive over the whole range of composition and at all temperatures. Excess Molar Volume. Excess molar volume values have been found to be positive which represent an intercalation packing effect, that is, an expansion of mixture caused by rupture of hydrogen bonds in self-associated alkoxypropanols due to presence of nonpolar molecules like alkyl esters. The positive values of excess molar volumes for the mixtures of alkoxypropanols and alkyl acetates is due to the difference in molecular size of the component which leads to less dipole− dipole interactions present in alkyl acetates. It seems that the hydrocarbon chain in alkoxypropanols plays a prominent role because as with the carbon chain length increases the van der Waal’s interaction dominates which is not compensated by the presence of hydrogen bonding. Overall, the positive excess molar volume increases as we increase the chain length of the alkoxypropanol except with BA. From Table 3 and Figure 1, it can be seen that excess molar volumes for the binary liquid mixtures (alkoxypropanols + esters) are all positive and tend to decrease with increase in chain length of esters. The positive values VEm vary in the algebraic order:

where x1, x2; M1, M2; and ρ1, ρ2 are the mole fractions, molar masses and densities of pure components 1 and 2, respectively. ρ and c are the densities and speeds of sound of the binary liquid mixture. The calculated values of VEm, κS, and ΔκS are reported in Table 3. The deviations of isentropic compressibility, ΔκS, from their ideal values were calculated from ΔκS = κS − κSid

The coefficients Ai obtained from least-squares method for the correlation of Y(x)-composition data along with the standard deviations σ are given in Table 4. The standard deviations were calculated using the following equation n

molar volumes; that is, positive deviations from ideality are observed at all temperatures. Further, with the increase in temperature the deviations in isentropic compressibilities values also increase for the present mixtures (Figure 4). It is clear that the alkyl chain length of the ester affects the isentropic compressibility behavior which is quite obvious. From Figure 5 it is observed that the ΔκS values become more positive as we decrease the chain length of the ester. Table 3 and Figure 5 show that a systematic increase in ΔκS (except with BA) is observed for all mixtures with the increase in the alkyl chain length of alkoxypropanols at all temperatures at x1 = 0.5. The sign and magnitude of ΔκS values are helpful in estimating the nature of interactions present between components of the binary liquid mixtures. The positive deviations in isentropic compressibility values indicate less intermolecular interactions between alkoxypropanols and ester molecules as the binary liquid mixture is more compressible than that of the corresponding ideal mixture.

The excess molar volumes at equimolar composition are represented in Figure 3, which implies that the positive values of VEm at equimolar composition vary as per the sequence: PGMME < PGMEE < PGMPE < PGMBE
From the data, it is observed that with increase in temperature the excess molar volume values also increase for the present mixtures, which are significant with BA (Figure 4). Maximum interactions are exhibited in all the mixtures around the mole fraction x1 = 0.5. Deviations in Isentropic Compressibility. Deviations in isentropic compressibilities as reported in Table 3 and shown in Figure 2 show the same behavior as observed in the case of excess 237

The average percentage deviation (APD) was calculated between experimental and calculated values to check the correlating ability of the model as follows APD = (1000/N )∑[(|Yexptl − Ycalcd|)/Yexptl]

where N is the number of data points in each set and Y represents density and speeds of sound values. The constants Ai calculated from the least-squares analysis along with average percentage deviation are reported in Table 4.
