Similar to the imidazolium ILs, very low solubility of the ammonium ILs was observed in alkanes. Eor example, the solubility of butyl(2-hydroxyethyl) dimethylammonium bromide, [(Ci)2C4HOC2N]Br, exhibited a simple eutectic system with immiscibility in the liquid phase in the IL mole fraction range from XjL = 0.02 to 0.70 [53] the other ammonium salt, (benzyl)dimethyl-alkylammonium nitrate, [Be(Ci)2C N] [NOJ showed very small solubility in the liquid phase in hexadecane and it was slightly better in hexane (immiscibility from XjL = 10 to 0.90) [99] for the ammonium salt with an alkane substituent only, didecyldimethylammonium nitrate, [(Cio)2(Q)2N][N03], the solubility in the liquid phase was better in hexane (immiscibility from XjL = 10 to 0.50) than in hexadecane, where the immiscibility was observed in the whole IL mole frachon [100]. In all systems with imidazolium and ammonium salts, an increase in the alkyl chain length of the alkane (solvent) resulted in a decrease of solubility. 

Monoalkyltrimethylammonium salts, e.g. cetyltrimethylammonium bromide. Monoalkyldimethylbenzylammonium chloride, e.g. benzalkonium chloride. Dialkyldimethylammonium salts, e.g. didecyldimethylammonium halides. 

Monoalkyldimethylbenzylammonium chloride, e.g. Benzalkonium chloride (18.1.2.). Dialkyldimethylammonium salts, e.g. didecyldimethylammonium halides (18.1.3.). Heteroaromatic ammonium salts (one R stands for a long-chain alkyl group, and the remaining three R are components of an aromatic system such as p5Tidine, quinoline or isoquinoline) e.g. cetylpyridinium halide and alkylisoquinolinium bromide (18.1.8.).
