A review, with 41 references, is given on the research progress in degradation of ionic liquids As”green solvents”, ionic liquids have attracted much attention in the area of electrochem., organic chem. and biochem. Recent studies focus on the synthesis and application of ionic liquids However, the studies on degradation of ionic liquids which concerned with environment are not enough. The degradation of ionic liquids is required before the large-scale use of ionic liquids In this study, chem. degradation method and biodegradation method are summarized. The chem. degradation is mainly achieved by UV/H2O2, Fe(III)/H2O2 and electrolysis system. Biol. degradation is achieved by introducing functional groups with enzymic site, or using monooxygenase to oxidize the Me terminal of alkyl side chain on the cation of ionic liquids into hydroxyl and aldehyde to form carboxylic groups, and then β-oxidation is carried out. Different chem. structures of ionic liquids are designed according to different mechanism between chem. and biol. degradation, for example, changing the length of alkyl chain or introducing the functional groups that are easily degradable and selection of microorganism could improve efficiency of degradation of ionic liquids In the experiment, the researchers used many compounds, for example, 1-Butyl-3-methylpyridinium Chloride (cas: 125652-55-3Application In Synthesis of 1-Butyl-3-methylpyridinium Chloride).
1-Butyl-3-methylpyridinium Chloride (cas: 125652-55-3) belongs to pyridine derivatives. Pyridine has a conjugated system of six π electrons that are delocalized over the ring. The molecule is planar and, thus, follows the Hückel criteria for aromatic systems. Several pyridine derivatives play important roles in biological systems. While its biosynthesis is not fully understood, nicotinic acid (vitamin B3) occurs in some bacteria, fungi, and mammals.Application In Synthesis of 1-Butyl-3-methylpyridinium Chloride
