Study On The Syntheses And Polymerizations Of Novel Functional Alkyl,Alkenyl Imidazolium Ionic Liquids

In recent years,ionic liquids as "green chemistry" in the field of research focus,with a wide process liquid,non-volatile,good electrochemical stability.Alkenyl ionic liquid as an ionic liquid,in recent years researchers in the field of attention,alkenyl ionic liquid carbon-carbon double bonds so that it has more functions and features,such as self-polymerization can be carried out to produce polymeric ionic liquids,it may also be prepared by graft copolymerization of new cellular polymer,thereby preparing a polymer material having an intelligent response,the polymer dispersing agent and a catalyst,conducting polymers,and other high-absorbency material functional polymer materials.Firstly,by alkylation reaction of N-methylimidazole,prepare two kinds of novel ionic liquids containing functional group,N-(6-hydroxyhexyl)-N'-methylimidazolium chloride(Compound 1),1,4-di(3-methyl-imidazol-1-ylmethyl)benzyl chloride(compound 2).Two novel ionic liquids using an infrared absorption spectrum TF-IR,1H-NMR NMR,13C-NMR nuclear magnetic resonance spectroscopy for structural characterization.Secondly alkenyl Two novel ionic liquids,i.e.,N-(2--allyl)-N'-methylimidazolium chloride(Compound 3)and 1,4-bis(3-methyl-imidazol-1-A yl)-2-butenyl bromide(compound 4).The two novel alkenyl ionic liquids using an infrared absorption spectrum TF-IR,1H-NMR NMR,13C-NMR nuclear magnetic resonance spectroscopy for structural characterization.Finally,to further prepare the novel ionic liquids with an alkenyl-N-(2-allyl)-N'-methylimidazolium chloride(compound 3)and 1,4-bis(3-methyl-imidazole-1-methyl)2-butene bromide(compound 4),respectively,by radical polymerization,we designed and synthesized two kinds of novel polymeric ionic liquids,namely poly N-(2-allyl)-N'-methylimidazole chloride(compound 5)and 1,4-poly(3-methyl-imidazol-1-ylmethyl)-2-butenyl bromide(compound 6).The two polymers ionic liquid structure by infrared absorption spectrum TF-IR,1H-NMR nuclear magnetic resonance spectrum,13C-NMR spectrum of nuclear magnetic resonance spectra.Poly-1,4-bis(3-methyl-imidazol-1-ylmethyl)-2-butenyl bromide(compound 6)thermal stability by differential thermogravimetric analyzer for testing.Papers were synthesized two novel ionic liquids alkyl,alkenyl two novel ionic liquids,two novel polymeric ionic liquids for use in the field of ionic liquids provides a variety of options.
