Parameters of viscous flow in dilute solutions of polyalkyl glycol ethers in secondary alcohols
(Elsevier Science, 2011-02)
Densities and viscosities were measured for the binary dilute mixtures of triethylene glycol monomethyl ether (TRIEGMME) in 2-alcohols (2-propanol (2-PR), 2-butanol (2-BU), and 2-pentanol (2-PE)) and tetraethylene glycol ...
Aqueous phase hydrogenolysis of glycerol to bio-propylene glycol over Pt-Sn catalysts
(Elsevier, 2012-05)
PtSn supported on SiO 2 obtained via surface organometallic chemistry techniques catalyzes hydrogenolysis of glycerol to obtain bio-propylene glycol (PG). Bimetallic catalysts with Sn contents between 0.1% and 1% wt were ...
Inhibition of Fluconazole In Vitro Antifungal Activity in Formulations Containing Propylene Glycol
(Colegio de Farmacéuticos de la Provincia de Buenos Aires, 2011-07)
Inhibition action of propylene glycol (PG) on the antifungal activity of fluconazole has been investigated. PG was used as cosolvent and penetration enhancer in different solutions and topical dosage forms. The interaction ...
Cerium ammonium nitrate: A new catalyst for regioselective protection of glycols
(Pergamon-Elsevier Science Ltd, 2004-12)
The regioselective introduction of a methoxymethyl (MOM) group on different type of glycols via an orthoester intermediate was investigated. The novelty presented in this study is the use of ceric ammonium nitrate instead ...

Structure and properties of biocompatible poly(glycerol adipate) elastomers modified with ethylene glycol
(Nature Publishing Group, 2017-08)
Polyesters poly(glycerol adipate)s or PGAs were prepared through a catalyst-free polycondensation reaction involving different proportions of adipic acid and glycerol. Additionally, another set of PGAs was formulated by ...
Viscosimetric behaviour of n-alkanols with triethylene glycol monomethyl ether at different temperatures
(Elsevier Science, 2008-03)
The thermodynamic functions of activation for viscous flow have been evaluated from the dynamic viscosity values of binary mixtures considering Eyring's transition state theory. Kinematic viscosities and densities of binary ...
Nanostructured Pt and Pt-Sn catalysts supported on oxidized carbon nanotubes for ethanol and ethylene glycol electro-oxidation
(Pergamon-Elsevier Science Ltd, 2011-03)
Pt and Pt-Sn catalysts supported on oxidized carbon nanotubes were prepared by multiple potentiostatic pulses and tested for ethanol and ethylene glycol electro-oxidation in sulfuric acid. The composed nanostructured ...
Weak interactions in cocrystals of isoniazid with glycolic and mandelic acids
(MDPI AG, 2021-03)
This work deals with the preparation of pyridine-3-carbohydrazide (isoniazid, inh) cocrystals with two α-hydroxycarboxylic acids. The interaction of glycolic acid (H2ga) or d,l-mandelic acid (H2ma) resulted in the formation ...
