Synthesis And Application Of Long Chain Amino Alcohols

Organic-inorganic hybrid materials because the collection characteristics of both organic and inorganic materials,so the design and synthesis of this kind of material is the hot spot of development in the field of material.This thesis reports the preparation of POSS-amino alcohol by the reaction of glycidyl POSS with aromatic amine in various imidazolium ionic liquids containing different anions and chloroform without catalysts.The successful formation of POSS-amino alcohol was confirmed and the reaction process was monitored by IR and NMR spectroscopy;the conversion of glycidyl POSS was identified via quantitative ¹³C-NMR spectroscopy.The synthesis of POSS-amino alcohol in [Hmim]Cl,[Hmim]Br,[Hmim]BF₄,and [Hmim]PF₆ ionic liquid was undesirable.Conversely,[Hmim]FeCl₄,[Hmim]Zn₂Cl₅,and [Hmim]AlCl₄ metallic imidazolium ionic liquids yielded more efficient ring-opening characteristics that were conducive to POSS-amino alcohol formation.The best conversion rate up to 100% only within 2h when [Hmim]AlCl₄ was used.In the application aspect,this thesis uses the POSS-amino alcohol as adsorbent,to adsorbe CO₂,The adsorption properties of POSS-amino alcohol on CO₂ were analyzed by TGA,The adsorption amount of CO₂ was determined by gravimetric method,and obtained the adsorption amount of POSS-amino alcohol of CO₂ is 0.36 mmol/g.
