1 Indian Journal of Pure & Applied Physics Vol. 43, December 2005, pp Molecular interaction studies of acrylic esters with alcohols P Sivagurunathan*, K Dharmalingam & K Ramachandran Department of Physics, Annamalai University, Annamalai Nagar, Tamilnadu Received 9 March 2005; revised 22 August 2005; accepted 27 September 2005 Hydrogen bonding between alcohols and acrylic esters in benzene has been studied by FTIR spectroscopic method. Utilizing Nash method the formation constant of the : complexes has been calculated. The formation constant and free energy change values vary with alcohol and ester chain length, which suggests that the proton donating ability of alcohols is in the order: -propanol < -butanol < -pentanol and the accepting ability of acrylic esters is in the order: methyl methacrylate < ethyl methacrylate < butyl methacrylate. Keywords: Molecular interactions, FTIR spectroscopy, Esters, Alcohols, Hydrogen bonding IPC Code: G0J3/28, C07C23/00 Introduction Acrylic esters are industrially important chemicals and precursors in the synthesis of polymers. The interaction study between associated and nonassociated liquids in benzene gives valuable information about solute-solute and solute-solvent interactions. Infrared study of alkyl acrylates and alkyl methacrylates in CHCl 3 and/or CCl 4 solutions have been reported by Nyquist and Streck 2. Smith and Rosenberg 3 have calculated the equilibrium constant of aliphatic ester-alcohols systems. Sastry and Dave 4,5 have measured the excess volumes, isentropic compressibilities, and dielectric behaviour of fifteen binary mixtures of alkyl (methyl, ethyl and butyl) methacrylates with several alkanols at K. Sastry and Valand 6 have measured the excess volumes of mixtures of alkyl (methyl, ethyl and butyl) acrylates with several alkanols at different temperatures. Werner et al. 7 have calculated the equilibrium constants and free energy changes for indole and diethylacetamide, indole and ethyl acetate, diphenylamine and diethylacetamide, diphenylamine and ethyl acetate and t-butanol and diethylacetamide in benzene. In the present work, an attempt has been made to study the hydrogen bonding between free hydroxyl and carbonyl groups of alcohol and acrylic ester in benzene. 2 Experimental Details A Nicolet Avatar 360 FTIR spectrometer with a resolution of ± cm - was used. Spectra were recorded at room temperature (298 K) in the region of 4000 to 400 cm - and NaCl cell of path length 0. mm was used. The spectrometer possesses autoalign energy optimization and dynamically aligned interferometer. It is fitted with a KBr beam splitter, a DTGS-Detector and Everlgo TM mid-ir source. The processing menu contains a spectra subtraction for eliminating solvent peaks in a spectrum of a sample that is dissolved in a solvent. A base line correction was made for the spectra recorded. The alkyl methacrylate monomers of molecular weights 00.2 (methyl methacrylate), 4.5 (ethyl methacrylate) and (butyl methacrylate) used in this investigation were purchased from Aldrich and used without further purification. AR grade benzene and alcohols were purified by standard methods 8,9. 2. Calculation of spectral parameters The spectral parameters are calculated by the following relations Δν=ν f -ν b () where Δν is the frequency difference between the free monomeric O-H and bonded O-H bands and ν f and ν b are the frequencies of free monomeric and bonded OH bands, respectively. Half-band width and integrated intensity were determined by the procedure given by Ramsay 0. Integrated intensity B is defined by B = cl I0 loge dν I (2) where, c is the total concentration, moles/liter of proton donor, l the cell length in cm, (l 0 /l), the

2 906 INDIAN J PURE & APPL PHYS, VOL 43, DECEMBER 2005 intensity of light transmitted and ν is the frequency in cm -. From the integrated intensities B in l moles - cm -, the change in dipole moment μ, with the normal coordinate Q, describing the vibration is given by dμ 3c = ± B dq N / 2 (3) where, c is the velocity of light and N is the Avogadro s number. 3 Results and Discussion The observed spectral data of primary alcohols (-propanol, -butanol and -pentanol) with benzene are given in Table. Alcohols in benzene exhibit two hydroxyl bands in the region of cm -, (i.e.) one is due to monomeric (O-H free) and the other is due to polymeric absorption (O-H bonded) and is shown in Fig.. Similar observation was reported by Werner et al. 7 for t-butanol + benzene system, (i.e.) free monomeric O-H band at 3592 cm - and bonded O-H band at 3450 cm -. The specific solute-solvent interaction observed for -alcohol + benzene system (i.e.) the interaction between the π-electron in the benzene ring with H δ in alcohol 2. The free monomeric O-H band frequency (ν f ), frequency difference between the free monomeric O-H and bonded O-H bands (Δν) and half-band width (Δν /2 ) are increasing with increasing carbon chain length of alcohol, whereas the reverse trend is observed for integrated intensity (B) and the change in dipole moment with the normal coordinate ( μ/ Q) values. But the frequency of the polymeric absorption band (3447 cm - ) is not influenced by the alcohol chain length 3-5. The infrared spectra of methyl methacrylate (MMA), ethyl methacrylate (EMA) and butyl methacrylate (BMA) in benzene are shown in Fig 2. From Table 2, the carbonyl absorption band of acrylic esters in benzene is observed in the order of methyl methacrylate > ethyl methacrylate > butyl methacrylate and the same trend is observed for integrated intensity (B) and the change in dipole moment with the normal coordinate ( μ/ Q) and a reverse trend is observed for the half-band width (Δν /2 ) 2,6. The interaction between the lone pair electron of oxygen atom of acrylic ester and the π electron of benzene exist in the system confirm the solute-solvent interaction 2.

For ternary mixtures, the proton acceptor (acrylic ester) concentration is fixed at molality and proton donor (alcohol) concentration varies from to molality in steps of 0.0 molality. The free O-H band intensity and Δν /2 increase with increasing alcohol concentration but at the same time the reverse trend is observed for the carbonyl absorption band and are shown in Figs 3-5. This observation indicates that there is : complex formation between free hydroxyl and carbonyl group (i.e.) (O-H O=C) (Ref. 3). The spectral data of the characteristic bands of the interactive systems are

In this method at low concentration of alcohol the influence of the higher order complexes on the absorption spectrum of base is neglected. The concentrations of the proton donor [A], proton acceptor [B] and complexed species [AB] involved in the interaction are assumed to be obeying Beer s law at a given characteristic frequency of the : complex. The total absorbance per centimeter path of B is given by a= ε b [B] + ε ab [AB] (4) where, ε b and ε ab are the molar absorbtivities of the species B and complexed species AB, respectively. In the absence of a complexing agent A the total absorbance per centimeter is given by a 0 = ε b [B 0 ] where [B 0 ] is the initial concentration of B. Dividing Eq. (4) by Eq. (5) a [ B] [ AB] ε. a B B The formation constant K may be defined as (5) ab = + (6) [ ] [ ] εb Introducing the conservation of species of B [B 0 ]= [B]+[AB] (9) Invoking Eq.

Eq. (5) rewrite in the form of linear equation as y = x (K -α) K (6) The physical significance of Eq. (6) is quite clear. When the reciprocal of the donor concentration is plotted against the reciprocal of one minus absorbance ratio gives a straight line for : complex formation. In addition to that, the intercept of the plot of y against x gives negative value may confirms : complex. The free energy change (ΔG 0 ) of the systems were calculated using the following relation 8 ΔG 0 = RT ln K (7) where R, T and K represent the universal gas constant, absolute temperature and formation constant of the relative systems, respectively. The formation constant (K) and the free energy change (ΔG 0 ) values for all the systems are given in Table 3. The K and ΔG 0 values for -propanol with all the proton acceptors are found to be lesser than that for -butanol and -pentanol with the same acceptors, which reveal that the proton donating ability of -propanol is lesser than that of -butanol and -pentanol 9. The K and ΔG 0 values for -propanol-methyl methacrylate system are found to be lesser than that of -propanol-ethyl methacrylate and -propanol-butyl methacrylate systems. This may be attributed to the difference in basicity of the alkyl groups, which vary in the order methyl < ethyl < butyl 20,2. This is EMA BMA because the negative inductive effect of the alkyl groups increases in the order methyl to butyl, and the electron contribution of the butyl group to the C=O group is significantly greater than that from the methyl group. Therefore, one would expect that the strongest intermolecular hydrogen bonds formed would be between the C=O group of butyl methacrylate and the OH proton of pentyl alcohol and the weakest between the C=O group of methyl methacrylate and the OH proton of propyl alcohol Conclusion The formation constant and free energy change of primary alcohols (-propanol, -butanol and - pentanol) with acrylic esters (methyl methacrylate, ethyl methacrylate and butyl methacrylate) in benzene are carried out. From this study, one may conclude that the proton donating ability of alcohols is in the order of -propanol < -butanol < -pentanol and the proton accepting ability of acrylic esters is in the order: methyl methacrylate < ethyl methacrylate < butyl methacrylate.
