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


  • Application of Fourier-Transform Infrared Spectroscopy for the Assessment of Wine Spoilage Indicators: This study showcases the use of isobutanol as a standard in assessing wine quality through spectroscopic methods, highlighting its role in ensuring the quality and safety of food and beverages (Teixeira Dos Santos et al., 2024).

  • Energy-Saving Electrochemical Hydrogen Production Coupled with Biomass-Derived Isobutanol Upgrading: Focuses on integrating isobutanol production from biomass with hydrogen production processes, illustrating its application in enhancing energy efficiency and renewable energy technologies (Du et al., 2024).

  • Effects of Core Size and Surfactant Choice on Fluid Saturation Development in Surfactant/Polymer Corefloods: Although indirectly related, this research can incorporate isobutanol as a component in formulations to optimize the extraction processes in the oil and gas industry, showcasing its role in industrial applications (Rovelli et al., 2024).
