Synthesis of Nanocomposites based on Poly (ionic liquid) for Different Applications in Water Treatment and Petroleum Industry

Abstract

Different types of hydrophobic, amphiphilic and hydrophilic ILs and PILs were prepared, characterized and applied in water treatment, nanomaterial preparations and petroleum applications. Also, new crosslinked PILs were prepared and applied for dye removal from aqueous solutions. The original work of this thesis comprises four main parts: The first part, hydrophobic ionic liquids were synthesized via ion exchange mechanism of 1-ally-3-methyl imidazolium chloride with cardanol, oleic acid and abietic acid. The prepared ILs gave high efficiencies as asphaltene dispersants. Also, superhydrophobic magnetite nanoparticles were prepared using hyrophobically modified 1-allyl-3-immidazolium oleate IL and showed high efficiency as oil spill collectors. The second part, dialkyl imidazolium ILs were synthesized via one-pot synthesis mechanism followed by ethoxylation with tetraethylene glycol to produce amphiphilic ILs. Furthermore, Cardanol as Cashew nut shell oil with m-pentadecyl phenol chemical structure was modified by incorporation of the hydrophilic amines and glycol to obtain new amphiphilic PILs. The prepared ILs and PILs acted as high efficient demulsifiers for heavy crude oil/ sea water emulsions. The third part, New protic PIL was prepared by the quaternization of AMPS monomer with DEEA followed by copolymerization with VP monomer to produce AMPSA/VP PIL. The prepared PIL was used as capping agent during the synthesis of ZnO, Ag and Fe3O4 nanoparticles. The prepared nanoparticles were applied for MB dye removal from aqueous
