A stable and catalytically active Au(III) complexes was obtained using Supported Ionic Liquid Phase (SILP) technol. The resulting heterogeneous Au-IL/AC catalysts combined the advantages of the catalytic species being stabilized in the Au(III) form by forming a Au(III)-IL complex and the need for a less expensive metal catalyst because the active component could be better developed in a homogeneous reaction medium. When used in acetylene hydrochlorination reaction, this catalyst displayed an excellent specific activity and superior long-term stability. Under the same reaction conditions, the Au(III)-IL/AC catalyst showed higher activity and stability towards the vinyl chloride monomer (VCM) than IL-free Au/AC (C2H2 conversion = 72.1% at 180° compared to 16.1% without IL). It also delivered stable performance within the conversion of acetylene, reaching more than 99.4%, and there was only a 3.7% C2H2 conversion loss after running for 300 h under the reaction conditions of a temperature of 180° and a C2H2 hourly space velocity of 30 h-1. Its exceptional ability to maintain the high activity and stability further demonstrated the potential for the replacement of Hg-based catalysts for acetylene hydrochlorination. In the experiment, the researchers used many compounds, for example, 1-Methyl-3-propylimidazolium Chloride (cas: 79917-89-8Safety of 1-Methyl-3-propylimidazolium Chloride).
1-Methyl-3-propylimidazolium Chloride (cas: 79917-89-8) belongs to imidazole derivatives. Imidazole derivatives generally have good solubility in protic solvents. Simple imidazole derivatives, such as 1H-imidazole, 2-methyl-1H-imidazole, and 1,2-dimethylimidazole, have very high solubility in water. Imidazole has been usedin the lysis, wash and elution buffer for the purification of histidine tagged Sonic Hedgehog(shh-N) protein, in elution buffer in stepwise gradient for the purification of histidine tagged aldo keto reductases using nickel affinity chromatography, as a component of homogenization buffer for the purification of phagosomal compartments from dendritic cells.Safety of 1-Methyl-3-propylimidazolium Chloride
