Natural deep eutectic solvents and aqueous solutions as an alternative extraction media for propolis
(2019-11-01)
Ethanolic extracts of propolis are consumed for their health benefits even though direct consumption of alcoholic extracts is not always ideal. Natural Deep Eutectic Solvents (NADES) can potentially extract similar compounds ...
Natural deep eutectic solvents as the major mobile phase components in high-performance liquid chromatography—searching for alternatives to organic solvents
(2018-06-01)
Over the past six decades, acetonitrile (ACN) has been the most employed organic modifier in reversed-phase high-performance liquid chromatography (RP-HPLC), followed by methanol (MeOH). However, from the growing environmental ...
State-of-the-art extraction and separation of enantiomers through the application of alternative solvents
(Elsevier, 2022-07)
Enantiomeric separation is an increasing research area, as well as the application of alternative solvents replacing classic volatile, flammable and toxic organic solvents. Among these novel solvents, chiral ionic liquids ...
Deacidification of vegetable oil by extraction with solvent recovery
(Springer, 2019-04)
Deacidification of a vegetable oil by extraction and regeneration of the solvent by means of adsorption was studied. This novel approach to solvent regeneration is posed as an alternative to distillation in systems with ...
Análise de rendimento da extração e solvente para o óleo de macadâmia
(Universidade Tecnológica Federal do ParanáPonta GrossaBrasilDepartamento Acadêmico De Engenharia QuímicaEngenharia QuímicaUTFPR, 2018-06-11)
Macadamia oil is considered one of the best nutritional oils among the obtained oils of nuts and hazelnuts. The chosen extraction to obtain oil is determinative for quality and quantity of the oil extracted, as well as, ...
The ionic liquid-surfactant bmim-AOT and nontoxic lipophilic solvents as components of reverse micelles alternative to the traditional systems. A study by 1H NMR spectroscopy
(Elsevier Science, 2020-04)
Aqueous reverse micelles (RMs) of the ionic liquid-surfactant 1-butyl-3-methylimidazolium 1,4-bis-2-ethylhexylsulfosuccinate (bmim-AOT) in the biocompatible nonpolar solvents isopropyl myristate (IPM) and methyl laurate ...
Obtenção de solventes para hidroformilação a partir de matéria-prima biorrenovável
(Universidade Federal de Minas GeraisBrasilICX - DEPARTAMENTO DE QUÍMICAPrograma de Pós-Graduação em QuímicaUFMG, 2021-04-30)
Dipentene and turpentine oil are co-products of the cellulose industry used as solvents in industrial processes. The presence of alkenes in the components of these oils makes them unsuitable as solvents for various reactions, ...

Estudo paramétrico da injeção alternada de vapor e solvente em reservatórios de óleos pesados
(BrasilUFRNPROGRAMA DE PÓS-GRADUAÇÃO EM CIÊNCIA E ENGENHARIA DE PETRÓLEO, 2018-02-01)
In the world, there are countless oil reservoirs with a long production history, but their production was ended, because they reached the limit of their economic viability, even still having a significant amount of oil. ...
