甲基咪唑胺类离子液体的合成及其对 ATRP 反应的影响
Synthesis of methyl imidazole amine ionic liquid for ATRP reaction system
摘要
Abstract
1-(Propyl amine)ethyl-3-methyl chloride ionic liquid ([N2 C3 MIM]Cl)was prepared on the base of N-methylimidazole by 1,2-dichloroethane to obtain the intermediates 1-chloro-ethyl-3-methyl chloride ionic liquid ([CeMIM]Cl) and then reacting with 1,3-propanediamine.The chemical structure of [N2 C3 MIM]Cl was confirmed by FT-IR and 1 H NMR. [N2 C3 MIM]Cl possessed a lower REDOX potential (-0.522 V)through cyclic voltammetry measurement,[N2 C3 MIM]Cl presented a perfect coordination property compared with organic ligands.The obtained ionic liquid [N2 C3 MIM]Cl coordinated with CuBr was used to catalyze atom transfer radical polymerization (ATRP ) of methyl methacrylate (MMA ) and it indicated by gel permeation chromatography (GPC ) that the coordination ionic liquid [N2 C3 MIM ]Cl presented the perfect controllability to the ATRP reactions.The residues of Cu2 + in polymerization product PMMA was only 270 mg·kg-1 by atomic absorption spectrometry determination.It showed that [N2 C3 MIM]Cl was conducive to the separation of catalyst from the obtained product compared with the traditional organic ligands.关键词
