Solvent fractionation of rambutan ( Nephelium lappaceum L.) kernel fat for production of non-hydrogenated solid fat: Influence of time and solvent type

open access: yesJournal of King Saud University - Science, 2017
The present study performed isothermal (25°C) solvent fractionation of rambutan (Nephelium lappaceum L.) kernel fat (RKF) to obtain the fat fraction that had melting properties comparable to a commercial hydrogenated solid fat.

Direct Correlation of the Salt-Reduced Diffusivities of Organic Solvents with the Solvent’s Mole Fraction

The Journal of Physical Chemistry Letters, 2022
Lithium bis(trifluoromethanesulfonyl)imide (LiTFSI) in organic solvents (especially propylene carbonate) has demonstrated extraordinary pseudocapacitive performance as an electrolyte in the supercapacitor configuration ( Nat. Energy 2019, 4, 241-248). However, the influence of the solvated ions on the diffusivity of the solvent molecules is yet to be ...

Fractionation of Compound Lipids by Dialysation in an Organic Solvent against an Organic Solvent

Nature, 1961
COMPOUND lipids in general are not dialysable in aqueous solution or emulsion because they form micelles. Their dialysability in organic solvents, however, has not been examined in detail ; but it seems to be largely dependent on the state of the organo-micelle1.

Fractionation - With or without Solvent?

Fette, Seifen, Anstrichmittel, 1986
By studying fractionation as a separation process it is possible to highlight a number of key features of the process. Although the partition of specific glycerides between liquid and solid phase is the foundation upon which the process rests, the entrainment in the subsequent liquid-solid separation dominates the overall effectiveness of the process ...

On-Column Solvent Exchange for Purified Preparative Fractions

JALA: Journal of the Association for Laboratory Automation, 2011
On-column solvent exchange, using many of the principles of solid-phase extraction, has been implemented to significantly reduce evaporation cycle time following reverse-phase preparative HPLC. Additional benefits, such as a reduced potential for salt formation, thermal decomposition, and residual solvent, are also described.

Fractionation of humic acid by organic solvents

Soil Science and Plant Nutrition, 1961
Abstract TJURIN (1) had proposed the use of organic solvent to fractionate humus. In his method, he extracted soils with benzene-alcohol (1 : 1) mixture in the SOXHLET's apparatus. The extract was dried at 80°C and weighed.

Solvent extract liquefaction of coal with fractionated anthracene oil and recycle solvent

Industrial & Engineering Chemistry Research, 1987
To estimate a solvent ability for coal liquefaction, 26 kinds of anthracene oils with widely ranging characteristics were used for Yallourn and Taiheiyo coal liquefactions. Hydrogen contents of solvents were correlated well with Yallourn coal conversion having a large coefficient of correlation (0.90), whereas less value was obtained for Taiheiyo coal (

Limitations of Solvent Fractionation Methods for Urinary and Faecal Porphyrins

Annals of Clinical Biochemistry: International Journal of Laboratory Medicine, 1998
The porphyrias are a group of rare, mainly inherited, disorders of haem biosynthesis, characterized by the accumulation and excessive excretion of haem precursors. Diagnosis relics heavily upon laboratory investigation, in particular the measurement of the prophyrin precursors 5-aminolaevulinic acid (ALA) and porphobilinogen (PSG) in urine, free ...

Solvent Effects on the Crystallization Behavior of Milk Fat Fractions

Journal of Agricultural and Food Chemistry, 2000
The high- and medium-melting fractions of milk fat (HMF and MMF, respectively) were crystallized in the presence of various solvents, including the low-melting fraction of milk fat (LMF), canola oil (CO), hexane, and ethyl acetate. Choice of solvent was shown to have a strong influence on phase behavior and crystallization kinetics.

Gelation of fractionated canine submaxillary mucin in a chaotropic solvent

International Journal of Biological Macromolecules, 1996
Rheological measurements have been performed on three molecular weight fractions of purified canine submaxillary mucin (CSM) dissolved in the chaotropic solvent 6 M guanidine hydrochloride (GdnHCI). Solutions of the lower molecular weight fractions are viscoelastic sols, and their dynamic moduli can be scaled with respect to molecular weight and ...
