The ultrasonic velocity (V), density (ρ) and viscosity (η) measurements of Hydroquinone in n-propanol and iso-propanol have been carried out for the study of solute-solvent interaction. Experimental data have been used to calculate the isentropic compressibility (b s ), intermolecular free length (L f ), specific acoustic impedance (Z), molar sound velocity (R), relative association (R A ) solvation number (S n ) apparent molal adiabatic compressibility (ϕ K ), specific viscosity (η sp ), reduced viscosity (η) and relative viscosity (η r ). The sign and magnitude of these properties have been used to interpret the experimental results in terms of solute-solvent interaction.
Synthetic organic chemists explore new methods for chemical transformation. In recent year lot of work has been carried out to use microwave irradiation as an alternative to conventional heating which provide higher yield and cleaner product.
ABSTRACTAn efficient synthesis for the preparation of some 2-amino-5-substituted phenyl-1,3,4-oxadiazoles by using both conventional and microwave method have been devised. The obtained results revealed that, microwave assisted technique is efficient, eco-friendly and inexpensive method which not only give higher yield but also reduces the reaction time significantly. The resulting compounds were characterized by IR, 1 H-NMR, UV-Vis and mass spectral analysis.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
