For example, a polar solvent e.g DMF and a non-polar solvent
e.g toluene are exposed to MW irradiation to achieve 90AdegC at same MW frequency and power level.
The fluent (menstruum) were applied in agreement with their polarity gradient with maceration scheduled from non-polar solvents
to polar solvents.
Polar solvents behave similarly to non-polar solvents
, whereas only hydrogen-bonding solvents, except for ethyl alcohol, show enhanced swelling.
Polar solvents are absorbed in much larger amounts than non-polar solvents
at sorption equilibrium.
Reversed-phase chromatography uses a gradient of strong to weak polar solvents with a non-polar packing material, whereas normal-phase chromatography uses a gradient of non-polar solvents
with a polar packing material.
The halogen bonded complexes of pyridine and perfluoroalkyl iodides, though stronger in polar solvents, showed significantly lower association constants in acetone and acetonitrile than in non-polar solvents
such as hexane and cyclohexane.
Key products within the Sun Protection program that showed superior SPF/UVAPF performance include Dow Corning[R] 5562 Carbinol Fluid, a low-viscosity fluid for sunscreens offering broad compatibility with polar and non-polar solvents
; Dow Corning 556 Cosmetic Grade Fluid, a polyphenylmethylsiloxane for suntan lotions that provides non-oily, easy-to-spread emolliency and a smooth, non-sticky film that helps repel sand; and Dow Corning MQ-1640 Flake Resin, a flexible film former for sunscreens that also provides wash-off resistance.
For phenolic extractions from botanical materials, polar and non-polar solvents
such as methanol, ethanol, acetone, water and hexane were used as solvents.
* BGP: Brilliant General Purpose Series for non-polar solvents
such as A _type gravure, make-and-use water-based coatings, and some plastisol applications
thomsonianum in different polar and non-polar solvents
restricted the growth of various bacterial and fungal strains.
Epoxies and cyanoacrylates are typically unaffected by non-polar solvents
like gasoline and motor oil, but when it comes to polar solvents such as acetone and isopropanol, cyanoacrylates perform poorly.
