The Kamlet-Taft dipolarity/polarizability parameters π* for various ionic liquids were determined using 4-tert-butyl-2-(dicyanomethylene)-5-[(4-N,N-diethylamino)-benzylidene]-Δ3-thiazoline and 5-(N,N-dimethylamino)-5′-nitro-2,2′-bithiophene as solvatochromic probes. In contrast to the established π*-probe N,N-diethylnitroaniline, the chromophores presented here show excellent agreement with polarity measurement using the chem. shift of 129Xe. They do not suffer from addnl. bathochromic UV/vis shifts caused by hydrogen-bonding resulting in too high π*-values for some ionic liquids In combination with large sets of various ionic liquids, these new chromophores thereby allow for detailed anal. of the phys. significance of π* and the comparison to quantum-mech. methods. We find that π* correlates strongly with the ratio of molar refractivity to molar volume, and thus with the refractive index. This study involved multiple reactions and reactants, such as N-Methyl-N,N-dioctyloctan-1-aminium chloride (cas: 5137-55-3Reference of 5137-55-3).
N-Methyl-N,N-dioctyloctan-1-aminium chloride (cas: 5137-55-3) belongs to organic chlorides. Organic chlorides can cause corrosion in pipelines, valves and condensers, and cause catalyst poisoning. The hydrocarbon processing industry (HPI) and others are affected by damage caused by these substances.While alkyl bromides and iodides are more reactive, alkyl chlorides tend to be less expensive and more readily available. Alkyl chlorides readily undergo attack by nucleophiles.Reference of 5137-55-3
