Oleic acid(112-80-1) is a single unsaturated carboxylic acid widely found in animal and vegetable oils. It has two types: stable (α-type) and unstable (β-type). It appears as a colorless transparent oily liquid with a lard odor. It is insoluble in water, soluble in benzene and chlor...
Niobic acid, (Nb2O5.nH2O), is a well-known solid acid that shows a fairly high acid strength in spite of large amounts of water being contained (~ 20 wt.-%). It is an amorphous material with BET surface area around 150 to 200 m2/g and average pore volume of 0.15 cm Vg. Its...
Solid–liquid phase behavior of binary fatty acid mixtures was investigated by means of differential scanning calorimetry (DSC) and Fourier transform infrared spectroscopy (FT-IR) for the mixture composed of oleic acid (OA) and stearic acid (SA) and that composed of OA and behenic acid (BA)....
Esterification of Pentanoic Acid with 1-Propanol by Sulfonated Cation Exchange Resin: Experimental and Kinetic Studies Liquid-phase esterification reaction of 1-propanol with pentanoic acid to give propyl pentanoate over Amberlyst 15 has been studied. The reaction carried o... M Sharma,AP Toor,RK...
3. The liquid phase boundaries have been established for each isotherm investigated and have been constructed on an enlarged scale. 4. The intersolubilizing effect of oleic acid on palmitic acid is greater in commercial hexane than in acetone although each acid is more soluble in ...
Samples were chromatographically resolved using a C18 column (YMC Pack ODS-AQ, 150 × 4.6 mm id; 3 μm) at a 1 ml/minute flow using 0.1% formic acid in water (A) and 0.1% formic acid in acetonitrile (B) as the mobile phase. Samples were loaded at 3% B ...
Generation of Solid Liquid Equilibrium (SLE) phase diagrams for real mixtures is extremely important to enable a thorough understanding of the thermodynamics of the fractionation process of crystallization. The PUFA mixture was fractionated in a multistage scrubbing layer crystallizer. The product was put...
Physical and chemical propertiesOleic acid(112-80-1) is a single unsaturated carboxylic acid widely found in animal and vegetable oils. It has two types: stable (α-type) and unstable (β-type). It appears as a colorless transparent oily liquid with a lard odor. It is insoluble in water...
According to the UV monitoring results, the separated components were combined into 10 groups using 30 μL of 2% acetonitrile and 0.1% formic acid. Then, the fractionated samples were analyzed using nano reverse-phase liquid chromatography Triple TOF 5600 (AB Sciex Inc.) using a Durashell-C18 ...
The liquid phase was separated in solvent A (water with 0.1 % formic acid) along with a linear solvent B gradient (100 % ACN with 0.1 % formic acid) at a flow rate of 300 nL/min. The peptide elution gradient was as follows: 0–2 min, –55 % B; 2–30 min, 5–38 % B; 30...
