Improving the Wetting Properties of Ionic Liquids

It has been found that additives which have formerly been employed exclusively in aqueous systems achieve the object of controlling the wetting and spreading behavior of ionic liquids. 

Polyethylene glycol cocosamine Polyethylene glycol stearylamine Octyl-jS-D-thioglucopyranoside Poly(propylene glycol) myristyl ether Sorbitan monolaurate Sorbitan trioleate 

N-Methyl-N,N-bis(2-hydroxyethyl)-N ocoammonium chloride Dimethylalkyl(C12-C16)benzylammonium chloride Dimethylstearylbenzylammonium chloride 

N-dimethyl(3-myristoylaminopropyl)ammonio]propanesulfon-ate (Amidosulfobetaine-14) l-(3-Sulfopropyl)pyridinium betaine 3-Dodecyldimethylammoniopropane-l-sulfonate 3-[(3-cholamidopropyl)dimethylammonio]-l-propanesulfonate Lauryl betaine Cocamidopropyl betaine n-d odecyl-N,N-d imethylglycine Tallowglycine Perfluorooctanesulfonate Perfluorinated carboxylic acids Perfluorooctanoic acid Fluorinated telomere alcohols Acetylene diols Acetylene diol alkoxylates Acetylene glycols
