Studies on molecular interactions of l-histidine/l-serine in aqueous diphenhydramine hydrochloride solutions at various temperatures: Volumetric, ultrasonic and viscometric approach

Thermophysical Studies on Molecular Interactions of Semicarbazide Hydrochloride/Domiphen Bromide in Aqueous Deep Eutectic Solvent Media at Various Temperatures

“…Still, for a better perception of intermolecular interactions, the limiting apparent molar volumes were assessed. Also, the uncertainty in apparent molar volume, δ V ϕ , has been determined via the formula expressed below where δρ refers to the uncertainty in the density of the prepared sample.…”

Effect of Tri-Sodium Citrate and Tri-Potassium Citrate on Solute–Solvent Interactions of Diphenhydramine-Hydrochloride Drug in Aqueous Solutions from the Viewpoint of Vapor Liquid Equilibria and Volumetric and Transport Properties

“…Volumetric and transport properties of solutions containing DPH-HCl, fructose, galactose, lactose, and water have been studied in our previous work for detecting the effect of fruit and milk sugars on solute–solvent interactions of systems considered . Volumetric and transport properties of DPH-HCl in water content solutions of NaCl, KCl, RbCl, MgCl 2 , CaCl 2 , and SrCl 2 have been studied by Sharma et al at 298.15–313.15 K. Measurements of volumetric, acoustic, and UV absorption properties have been used to determine the molecular interactions in solutions containing DPH-HCl, 1-hexyl-3-methylimidazolium chloride1, 1-methyl-3-octylimidazolium chloride, 1-butyl-3-methylimidazolium chloride, and water at T = 293.15–313.15 K by Singh et al Behboudi et al studied the interactions of DPH-HCl with choline bi-tartrate and choline lactate by measuring the thermodynamic, volumetric, and transport properties in aqueous solutions at T = 288.15 to 318.15 K. Volumetric, ultrasonic, and viscometric properties were also utilized by Bandral et al to study the systems containing DPH-HCl, l-serine, l-histidine, and water at 293.15–318.15 K. Water activity has been measured and correlated in aqueous solutions containing diphenhydramine hydrochloride in our previous works. , VLE, volumetric, and transport properties of tri-sodium citrate, Na 3 Cit, and tri-potassium citrate, K 3 Cit, in aqueous solutions have been measured in several studies. − All the results obtained in these works have been interpreted according to solute–solvent interactions in terms of hydrophilic hydration around the polar head groups of drugs, hydrophobic hydration around the aromatic rings on drugs, and hydrophilic–ionic interactions between the – + NH 3 R/–OCHPh 2 /Cl – ,/group of DPH-HCl and ions of electrolytes.…”
