Decomposition of Ionic Liquids by Photocatalysis

Amethod for the decomposition of ionic liquid (ILs) by photocatalysis has been demonstrated. The participation of ILs in light absorption by TiO2 was shown. The IL molar mass influence on photocatalytic decomposition was proven. The samples with a lower molarmass had higher stability under UVlight in the presence of TiO2. The degree of decomposition depends upon the cation and anion. The easiest to degrade proved to be ILs with a long alkyl substituent. Ammonium ILs (choline derivatives) with hydroxyl group proved to bemore stable than with acetyl group. Themost readily decomposable salts are phosphonium ionic liquids.

EN
New room temperature ionic liquids - choline derivatives were prepared by Menschutkin reaction with alkyl chloromethyl ethers and anion changed to bis(trifluoromethylsulfonyl) amide ion. The newly obtained butoxymethyl(2-hydroxyethyl)dimethylammonium bis(trifluoromethanesulfonyl)amide was successfully tested as a solvent for O-acylation in two-phase reaction system. The ionic liquid-catalyst system was recycled and reused.

The Antielectrostatic Effect of N-Alkanol-N-alkoxymethyl-N,N-dimethylammonium Chlorides and Their Ester Derivatives

Several new quaternary ammonium chlorides, analogues of choline, were prepared by reaction of 2-(dimethylamino)ethanol and its derivatives with chloromethyl alkyl ethers. The obtained chlorides were examined in respect to their antielectrostatic effects: the surface resistance and half decay time on polyethylene film were measured. Application of rough set theory permitted to perform a comprehensive analysis of data and detection of structural-activity relationships. The obtained chlorides showed high antielectrostatic properties. The most active were quaternary ammonium chlorides with 11 and 12 carbon atoms in alkyl chain.
