Comparison of two methods for the separation of polar from nonpolar lipids.
نویسنده
چکیده
The countercurrent extraction method of Galanos and Kapoulas for the separation of phospholipids from triglycerides was compared with dialysis in petroleum ether in an apparatus modified from that of Eberhagen and Betzing. The efficiencies of the methods are similar, but dialysis, which is slower, can yield triglycerides that are entirely free from phosphorus. The behavior of free fatty acids and monoglycerides is also described.

Separation of Aromatic and Alcoholic Mixtures using Novel MWCNT-Silica Gel Nanocomposite as an Adsorbent in Gas Chromatography
The separations of alcohols with hydrophilic and hydrophobic parts, and the separation of aromatic mixtures, are extremely important processes in gas and petroleum industries. Choosing an adsorbent for performing this separation is the most important part of the process. Silica gel is used as an adsorbent is various techniques such as pressure swing adsorption (PSA) and gas and liquid chromatog...
متن کاملAntimicrobial activities of semi polar-nonpolar and polar secondary metabolites of sponge Dysidea pallescens from Hengam Island, Persian Gulf
Sponges are the simplest multicellular animals that lack defense mechanisms and rely on chemical defense that have been used by mankind to develop antimicrobial drugs against diseases. The present study was designed to demonstrate the antibacterial and antifungal activities of marine sponge Dysidea pallescens semipolar and nonpolar extracts. In this study, D. pallescens were collected from He...
متن کاملAn Improved Correlation for Second Virial Coefficients of Pure Fluids
In the present work, a modified correlation is presented for the second virial coefficients of both polar and nonpolar fluids based on the corresponding states principle. The second virial coefficients of gaseous polar and non-polar compounds were calculated and compared with experimental data and with other correlations. Comparisons with the existing correlations show that the present work is ...

متن کاملPhysical separation of amphiprotic-polar aprotic solvents for simultaneous extraction and clean-up of clomiphene from plasma before liquid chromatographic analyzes
An efficient and quantitative two phase freezing (TPF) method coupled with high performance liquid chromatography and UV-Vis detector was developed for the extraction, clean up and determination of clomiphene citrate (CLC) in plasma samples. The separation of two miscible solvents by TPF method permits that the CLC was efficiently removed from proteins and transferred into the relative aprotic ...
