Imidazolinium Ionic Liquid Crystal Catalysts

—A general discussion on ionic liquid crystals has already been made (see Chapter 2), and this section includes some commercially available liquid crystal 1,3-dialkylimidazolinium salts that participate in the catalytic process, i.e. by coordination with the metal component of catalysts, as well as assisting in other ways such as acting as a solvent, affecting the dielectric, and in phase transference of reagents. Depending on the N-alkyl substituents and the counter anion the salts may be more, or less, soluble in water or organic solvents. They are non-volatile (i.e. environmentally friendly), stable to water and air, and many may be heated to temperatures as high as 300°, making it possible to ...
