A two-dimensional nuclear Overhauser effect spectroscopy (NOESY) study of the complex fluid 2-ethylhexyl benzoate (EHB) was performed at -20°C and 0°C up to pressures of 3000 bar. The high-pressure/low-temperature capability of the NMR set-up allowed the experiments to be done under conditions of very slow mol. motion where proton homonuclear cross relaxation rates were large in magnitude and NOESY cross peaks were significantly intense and fast-growing. Intramol. cross relaxation rates were determined by measuring cross peak build-up rates as a function of isotopic dilution of EHB in perdeuterated EHB (EHB-d22) and extrapolating to infinite dilution A direct correlation between the rate of cross relaxation and viscosity/temperature was found and was explained in terms of the Debye expression. Insight into the time scales involved in mol. reorientation was also gained by calculation of correlation times. Internuclear cross relaxation rates were similarly investigated and related to the inverse of the rate of translational diffusion through Torrey’s translational model for relaxation. Finally, internuclear distances calculated from intramol. cross relaxation rates were used in conjunction with a mol. mechanics program to grain qual. information about possible EHB conformations. This study involved multiple reactions and reactants, such as 2-Ethylhexyl benzoate (cas: 5444-75-7Recommanded Product: 5444-75-7).
2-Ethylhexyl benzoate (cas: 5444-75-7) belongs to esters. Esters typically have a pleasant smell; those of low molecular weight are commonly used as fragrances and are found in essential oils and pheromones. Esters contain a carbonyl center, which gives rise to 120° C–C–O and O–C–O angles. Unlike amides, esters are structurally flexible functional groups because rotation about the C–O–C bonds has a low barrier. Their flexibility and low polarity is manifested in their physical properties; they tend to be less rigid (lower melting point) and more volatile (lower boiling point) than the corresponding amides.
