Title : Study of dielectric and acoustic characterizations of alcohols with amide


The present paper explains the study of Static Permittivity, Density and Ultrasonic Velocity and derived properties for the binary mixtures of Dimethylacetamide (DMA) with four isomers of tertiary alcohols over the entire concentration range were measured at 300 K. Using Experimental parameters, Bruggeman factor, compressibility, and acoustic impedance, molecular free length, inverse relaxation time, Gibbs Free energy, Enthalpy of activation, Entropy and excess parameters were calculated. The values of excess properties afterward fitted with Redlich–Kister polynomial equation to estimate the standard deviation. The excess parameters were used to study the interactions between the molecules inside the binary mixtures. Results confirm that strong hydrogen-bonded intermolecular interaction occurs between due to contraction in the volume in DMA and isomers of tertiary alcohol. Results also confirm that branched-chain structured tert-alcohols + DMA shows the most potent interaction as compared to DMA+ other isomers of Butanol. 
Keywords: Bruggeman factor, Compressibility, Excess dielectric constant, Excess inverse relaxation time
Audience Take Away: 

  • Audience will get detailed regarding dielectric constant and relaxation time and its use to calculate other derived parameters and excess parameters. Further these parameters are also used to interpret type of intermolecular interactions, strength of bonding, dynamics of intermolecular interactions.
  • These intermolecular interactions study is very useful in chemical, medical, paint and material science.
  • Yes, this research that other faculty could use to expand their research or teaching with proper permission from author.
  • This study provides a solution to a problem that could simplify to reduce further efforts of drugs/pharmaceuticals / chemical industry
  • Yes, it improves the accuracy of a molecular design, or provide new bonding and molecular dynamics information to assist in a molecular design problem
  • This study may be used in ceramic, chemical, agricultural study also.
