Description

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

• Oil sludge washing with surfactants and co-solvents: This study by Ramirez et al. explored the effectiveness of various solvents, including n-Pentane, in recovering oil from different types of oil sludges, focusing on environmental remediation technologies (Ramirez D, Shaw LJ, Collins CD, 2021).


• Physicochemical properties of organic solvents in nanoparticle synthesis: Fromme et al. studied the impact of organic solvents, such as n-Pentane, on gas and hydrogen formation during laser synthesis of gold nanoparticles, highlighting its application in materials science (Fromme T, Tintrop LK, Reichenberger S, Schmidt TC, Barcikowski S, 2023).


• Thermodynamic assessment in extraction processes: Al-Maari et al. assessed the efficiency of n-Pentane as a solvent in the extraction of vegetable oils using thermodynamic models, which is crucial for food and pharmaceutical industries (Al-Maari MA, Hizaddin HF, Salleh MZM, Hayyan A, 2024).
