Ultrasonic study of substituted-2,3‐dihydroquinazolin‐4(1H)‐ones in 70% DMF-Water

Author(s): D. S. Hedaoo, M. M. Kalaskar and M. P. Wadekar

Density and ultrasonic velocity measurements are carried out for substituted -2,3-dihydroquinazolin-4(1H)-ones in 70% DMF-Water at T= 303K. The experimental values are used to calculate intermolecular free length (Lf), specific acoustic impedance (Z) and relative association (RA). These acoustic parameters obtained are used to explain the interaction taking place in the solutions.
