dimethyl-formamide (DMF), dimethyl sulfoxide (DMSO), acetonitrile, methanol, and glyceryl usually performs better under MW irradiation because they can absorb MW irradiation better than non-polar solvents
They stated that swelling in non-polar solvents
followed the regular solution theory, and the coal solubility parameters determined were about 9.5 [(cal/[cm.sup.3]).sup.1/2].
It is then observed in Table 1 that polar solvents are absorbed in higher amounts than non-polar solvents
. Since PA66 is a highly polar polymer, polar solvents have an affinity to PA66 because these molecules can form H-bonds with polyamide chains.
This indicates that the enthalpy change for the halogen bonding formation is more negative in polar solvents than in non-polar solvents
. On the other hand, in Table 2, the halogen bonding association constants are greater in nonpolar solvents than those in polar solvents.
These higher values coincided with their high contents of EPPs which could be attributed to the high polarity of the solvent that is more effective in the recovery of antioxidant compounds than non-polar solvents
(DORTA et al., 2012).
Different polar and non-polar solvents
were used for the extraction and thus their antimicrobial aspect and different values of inhibitory action against the microbes in mm were observed.
Combination with further dispersing additives also permits the compatibility of non-polar solvents
, such as hydrocarbons, to be adjusted to that of polar solvents.
Lipids present in algal cells are generally hydrophobic molecules that interact with moderately non-polar solvents
such as ethyl ether, chloroform, acetone and benzene.
Considering that devices commonly contain (intentionally or not) both polar and non-polar substances, and the body is composed of both polar and non-polar fluids and membranes, extraction with both polar and non-polar solvents
The extraction principle is to dissolve the polar substances in polar solvents and non-polar substances in non-polar solvents
Ingredients used in construction adhesives include clay, cement, acrylic resin, polyurethane monomers, styrene-butadiene rubber, hexane, other non-polar solvents
, and various initiators and functional additives.
