Catalytic system consisting essentially of at least one ionic liquid comprising at least one non-protonated cation and at least one anion selected from chloride and methanesulfonate and its use in the hydrochlorination reaction of acetylene with hydrogen chloride.
constructed from the tetrabutylphosphonium cation and decavanadate, has been synthesized and unequivocally characterized by elemental analysis, FTIR spectroscopy, mass spectrometry, X-ray crystallography, and solution 1H, 13C, 31P1H}, and 51V NMR spectroscopy. Compound IL01-V10 was formed by ionic interaction between the phosphonium cation and the decavanadate anion. Cryospray high-resolution mass spectrometry
