Popis

General description

EMPLURA^® is our low-cost alternative to high-purity qualities. With EMPLURA we offer a range of solvents for a plurality of basic applications in non-regulated industries and for less demanding applications, preparative laboratory work and cleaning purposes. EMPLURA solvents provide adequate specifications with the most important parameters.

Application

• The effect of hydrogen bonding on the diffusion of water in n-alkanes and n-alcohols measured with a novel single microdroplet method.: This research investigates the diffusion behavior of water in n-pentane and other n-alkanes, emphasizing the role of hydrogen bonding. The novel single microdroplet method used in this study provides detailed insights into the molecular interactions and diffusion processes (Su et al., 2010).


• Enthalpy of solution of 1,4-naphthoquinone in CO2 + n-pentane in the critical region of the binary mixture: mechanism of solubility enhancement.: This paper explores the solubility mechanisms of 1,4-naphthoquinone in a CO2 and n-pentane mixture, particularly in the critical region. The study reveals how n-pentane enhances the solubility of organic compounds in supercritical CO2, with implications for industrial applications (Mu et al., 2004).


• Metabolism of n-pentane by ethanol-inducible cytochrome P-450 in liver microsomes and reconstituted membranes.: This research investigates the metabolic pathways of n-pentane in the presence of ethanol-inducible cytochrome P-450. The findings elucidate the role of specific enzymes in the biotransformation of n-pentane, with significant implications for toxicology and pharmacology (Terelius & Ingelman-Sundberg, 1986).
