2-chlorobenzonitrile (2-ClBN) is widely used in the manufacturing of azo dyes, pharmaceuticals, and as intermediate in various chemical reactions. The aim of present study was to evaluate the impact of biofield treatment on physical, thermal and spectroscopic properties of 2-ClBN. 2-ClBN sample was divided into two groups that served as treated and control. The treated group received Mr. Trivedis biofield treatment. Subsequently, the control and treated samples were evaluated using X-ray diffraction (XRD), surface area analyser, differential scanning calorimetry (DSC), thermogravimetric analysis (TGA), Fourier transform infrared (FT-IR) and ultraviolet-visible (UV-Vis) spectroscopy. XRD result showed a decrease in crystallite size in treated samples i.e. 4.88% in 2-ClBN along with the increase in peak intensity as compared to control. However, surface area analysis showed a decrease in surface area of 64.53% in treated 2-ClBN sample as compared to the control. Furthermore, DSC analysis results showed a significant increase in the latent heat of fusion (28.74%) and a slight increase in melting temperature (2.05%) in treated sample as compared to the control. Moreover, TGA/DTG studies showed that the control and treated 2-ClBN samples lost 61.05% and 46.15% of their weight, respectively. The FT-IR spectra did not show any significant change in treated 2-ClBN sample as compared to control. However, UV-Vis spectra showed an increase in the intensity of peak as compared to control sample. These findings suggest that biofield treatment has significantly altered the physical, thermal and spectroscopic properties of 2-ClBN, which could make them more useful as a chemical intermediate.
The overall study showed the influence of biofield treatment on physical, thermal and spectroscopic properties of 2-ClBN. XRD results showed that crystallite size was decreased by 4.88% in treated 2-ClBN samples as compared to control, which might be due to fracturing of grains into subgrains caused by lattice strain produced via biofield energy. The increase in the intensity of peaks suggests the increased crystallinity of treated sample due to the formation of symmetrical and organised molecular layers caused via biofield treatment. The reduced crystallite size and increased crystallinity may lead to increasing the reaction kinetics as well as the stability of 2-ClBN, which could make it more useful as an intermediate compound. The surface area analysis showed 64.53% decrease in surface area of the treated 2-ClBN sample as compared to the control that might result due to increase in crystallinity and formation of a well-crystallised sample after biofield treatment. DSC analysis data revealed that latent heat of fusion as well as melting temperature were increased by 28.74% and 2.05% respectively in treated 2-ClBN as compared to control. TGA/DTG studies showed that onset temperature and Tmax were increased by 5.3% and 3.23% respectively in treated 2-ClBN samples. On the basis of thermal analysis data, it is hypothesized that thermal stability of treated 2-ClBN sample increased which may affect its shelf life and efficacy when used in various chemical reactions. The UV-Vis spectra showed alteration in the intensity of peaks that might happen due to increase in intermolecular bonding in 2-ClBN molecules after biofield treatment. This increase in intermolecular bonding can further relate to increased thermal stability of treated sample as compared to control. Therefore, it is assumed that biofield treated 2-ClBN could be more useful in the production of various pharmaceutical products.
