摘要:The present disclosure relates to a procedure for the synthesis of polymers (homo and copolymers) of the poly (ionic liquid) (PIL) type. The homopolymers are derived from polyvinylimidazolium, polyvinylpyrrolidone or polyvinylpyridine and the copolymers from monomers of vinyl ionic liquids (ILs) are derived from imidazole and N-vinylpyrrolidone. The structural modification of these homopolymers and copolymers occurs by using strong inorganic acids such as sulfuric, chlorosulfonic and bromosulfonic, among others, and halide metallic salts such as AlCl3, FeCl3, CuCl, ZnCl2, and SnCl2. Also, these PILs are employed as catalysts in alkylation reactions between isoparaffins and olefins for producing alkylate gasoline.

摘要:Compositions and methods of synthesis of anionic surfactants by alkoxylation of a Guerbet alcohol (GA) having 12 to 36 carbon atoms using butylene oxide, and optionally propylene oxide and/or ethylene oxide followed by the incorporation of a terminal anionic group are described herein. The GA of the present invention is made by a facile and inexpensive method that involves high temperature base catalyzed dimerization of alcohols with 6 to 18 carbon atoms. The large hydrophobe ether surfactants of the present invention find uses in enhanced oil recovery (EOR) applications where it is used for solubilization and mobilization of oil and for environmental cleanup. Further, the hydrophobe alkoxylated GA without anionic terminal group can be used as an ultra-high molecular weight non-ionic surfactant.
