fat sol·'vents

organic liquids notable for their ability to dissolve lipids; usually, but not always, immiscible in water; for example, diethyl ether, carbon tetrachloride.

low moisture and water vapor permeability, and excellent chemical resistance against polar solvents and solutions including acids, bases, esters, and alcohols but only moderate heat resistance and poor chemical resistance against nonpolar solvents like alkanes, ethers, and oils.
Unlike silicone, fluorosilicone contains tri-fluoropropyl groups that enhance its chemical resistance to nonpolar solvents, fuels, oils, acids and alkaline chemicals at temperatures between -70[degrees]F and 450[degrees]F.
There are two main objectives to my PhD, one is a theoretical approach to understanding colloid interactions in nonpolar solvents, and the other is to investigate the structure of polymer-surfactant complexes found in shampoo.
Schoonheydt and Johnston [37] reported that the absorption maxima of dye molecules in nonpolar solvents adsorbed onto the surface of clay minerals could shift to shorter wavelengths because the solvent-molecule interaction was stronger in the ground state than in the excited state.
The Si-NPs exhibit good luminescence spectra in some nonpolar solvents but its stability is very limited [18].
The selection of the solvents was guided by their polarity, from nonpolar solvents (n-hexane), midpolar solvents (dichloromethane and acetone) to high-polar solvents (methanol and water).
Effect of solvents: Organic nonpolar solvents were used to determine the activities of lipase and phospholipase.
The nonpolar target chemicals are generally eluted by nonpolar solvents such as HEX and DCM [19,23,25,34].
The calculations performed with two theoretical models, B3LYP-D2 and M05-2X, in polar and nonpolar solvents, proved to be in good accordance.
The crude extracts of powdered plant material were obtained in various polar and nonpolar solvents, viz: petroleum ether, chloroform, methanol and distilled water.
1,4-bis (triphenylphosphonium) butane cerium nitrate 2 is a stable compound and can be stored for a long period without losing its activity Compared to K2Ce(NO3)6, Na2Ce(NO3)6 and (NH4)2Ce(NO3)6, the readily prepared reagent 2 can be used in general organic reactions due to dissolving effectively and easily in various solvent such as polar protic, aprotic and nonpolar solvents. As shown in Scheme 2, a mixture of oxidant 2 and alkyl- substituted benzenes was stirred in refluxing 1:1 molar ratio with CH3COOH and H2O for an appropriate time (Table-1) at room temperature.
150 mL methanolic non-polar extract was then be subjected to fractionation using a series of nonpolar solvents with increasing polarity.
