Mathematical representation of the density of liquid mixtures at various temperatures using Jouyban-Acree model
No full text1553-1560Applicability
of a quantitative relationship of density with mixture composition and temperature
of liquid mixtures is shown using 98 density data at various temperatures, with
an overall average percentage deviation (OAPD) as accuracy criterion. The OAPD of
the Jouyban-Acree model is also compared with those of three previously
published equations and the OAPD (±SD) of the proposed and previous equations
are 0.05 ± 0.06, 0.12 ± 0.15, 0.16 ± 0.22 and 0.15 ± 0.22, respectively. The
differences between OAPD of the Jouyban- Acree model with those of previous
models are statistically significant (p0.0005). The
prediction capability of the proposed model is also compared with that of the
best reported correlative equation and the proposed model provides more
accurate predictions

Deviations of drug solubility in water-cosolvent mixtures from the Jouyban-Acree model: effect of solute structure
No full textDeviations of the predicted solubilities using the Jouyban-Acree model from experimental data were correlated to the structural descritptors of the drugs computed by HyperChem® software. The proposed models are able to predict the solubility in water-cosolvent mixtures and reduced the mean percentage deviations (MPD) of predicted solubilities from 24, 48, and 53 to 16, 33 and 38, respectively for water-propylene glycol, water-ethanol and water-polyethylene glycol 400 mixtures, with the overall improvement in prediction capability of the model being ~13%

Equilibrium solubility and apparent specific volume at saturation of sodium sulfadiazine in some aqueous cosolvent mixtures at 298.2 K
No full textEl objetivo principal de esta investigación fue determinar y correlacionar la solubilidad en equilibrio de sulfadiazina de sodio en varias mezclas de {cosolvente (1) + agua (2)} a 298.2 K. Los codisolventes fueron formamida, N- metilformamida, N, N -dimetilformamida, dimetil sulfóxido, N-metil-2-pirrolidona, 1,4-dioxano y metanol. Se usó el método clásico de matraz de agitación para determinar la solubilidad isotérmica. Las mediciones de la concentración del fármaco se realizaron mediante determinaciones de conductividad eléctrica después de diluciones acuosas adecuadas. La solubilidad de la sulfadiazina de sodio disminuye de forma no lineal con la adición de cosolvente al agua en casi todas las composiciones de mezclas. Los modelos Jouyban-Acree y Jouyban-Acree-Abraham correlacionan los valores de solubilidad con la composición de mezclas para todos los sistemas cosolventes. Además, el volumen específico aparente de este fármaco en la saturación también se calculó a partir de la densidad y las composiciones de mezclas.The main objective of this research was to determine and correlate the equilibrium solubility of sodium sulfadiazine in several {cosolvent (1) + water (2)} mixtures at 298.2 K. Cosolvents were formamide, N-methylformamide, N,N-dimethylformamide, dimethyl sulphoxide, N-methyl-2-pyrrolidone, 1,4-dioxane, and methanol. Classical shake-flask method was used to determine isothermal solubility. Drug concentration measurements were performed by means of electrical conductivity determinations after adequate aqueous dilutions. Solubility of sodium sulfadiazine decreases non-linearly with the addition of cosolvent to water in almost all mixtures compositions. The Jouyban-Acree and Jouyban-Acree-Abraham models correlate the solubility values with the mixtures composition for all cosolvent systems. Furthermore, the apparent specific volume of this drug at saturation was also calculated from density and mixtures compositions.http://scienti.colciencias.gov.co:8081/cvlac/visualizador/generarCurriculoCv.do?cod_rh=0001402116https://orcid.org/0000-0002-4835-9739https://scienti.colciencias.gov.co/gruplac/jsp/visualiza/visualizagr.jsp?nro=00000000004151danielr.delgado@campusucc.edu.cohttps://scholar.google.com/citations?hl=es&user=OW0mejcAAAAJ&view_op=list_work
