Solubility of hydrocarbons in water is important due to ecological concerns and new restrictions on the existence of organic pollutants in water streams. Also, the creation of a thermodynamic model has required an advanced study of the phase equilibrium between water (as a basis for the widest spread muds and amines) and gas hydrocarbon phases in wide temperature and pressure ranges. Therefore,...

The solubility of K2SO4 in water at 25°C was determined. Comparing the value ofthermodynamic solubility product constant, Ksp(th), (Ksp(th) = exp (-ΔGodiss RT) of the mentionedsalt to the value of concentration solubility product, Ksp(c) which is obtained from the observedsolubility, s/moL-1, Ksp(c) = 4s3, revealed a great difference. The difference can be satisfactorilyexplained using Debye- H...

INTRODUCTION Solubility of root filling materials is heavily influenced by the environment they are in contact with. This study compared the solubility of ProRoot MTA in deionized water and synthetic tissue fluid. MATERIALS AND METHODS Forty specimens of prepared MTA were immersed in deionized water and synthetic tissue fluid (20 samples each). The solubility was assessed after 7 and 28 days....

The aim of this study was to evaluate the water sorption and solubility of different adhesives. Adper Easy Bond, Adper Single Bond Plus, Bond Force, Clearfil SE Bond (bonding resin only), and Xeno IV were the materials evaluated. Ten disks of each adhesive were made in Teflon molds and evaporation of any volatile components was allowed. The disks were weighed daily in an analytical balance unti...

OBJECTIVES The absorption of water by acrylic resins is a phenomenon of considerable importance since it is accompanied by dimensional changes, a further undesirable effect of absorbed water in acrylic resins to reduce the tensile strength of the material. Solubility is also an important property because it represents the mass of soluble materials from the polymers. METHODS Ten acrylic resin-...

Extended Hildebrand solubility approach is used to estimate the solubility of nabumetone in binary solvent systems. The solubility of nabumetone in various propylene glycol-water mixtures was analyzed in terms of solute-solvent interactions using a modified version of Hildebrand-Scatchard treatment for regular solutions. The solubility of nabumetone in the binary solvent, propylene glycol-water...

The solubility of KNO3 in the mixed solvent (water 85%+methanol 15%) were determined by using solvent evaporating method at different temperatures (25, 30, 40, 50, 60 ;C). In addition the equilibrium constant of ion pair formation, KIP, for K+NO3 – ion-pair on the basis of Fuoss contact ion pair model was calculated. Upon choosing the extended Debye-Hückel model for estimating the mean activity...

The extended Hildebrand solubility parameter approach is used to estimate the solubility of nabumetone in binary solvent systems. The solubility of nabumetone in various dioxane-water mixtures was analyzed in terms of solute-solvent interactions using a modified version of Hildebrand-Scatchard treatment for regular solutions. The solubility of nabumetone in the binary solvent, dioxane-water sho...

Due to low cost, ease of administration, and lack need for trained personnel, the oral route is the most convenient and accessible way to design different medicines that could be simply consumed by patients. Regardless of the great benefits of this route, the main challenge in the bioavailability of oral medications is gastrointestinal instability. Nanotechnology is used to improve the solubili...
