    Ionic liquids for acetylene and ethylene separation .

    The use of volatile organic solvent for the gas storage reduces the purity of acetylene because it can exhaust together with the gas stream. Therefore, it is also our motivation to search high capacity, non-flammable, and less volatile solvents suitable for the acetylene storage technology.

    Imidazole-1-sulfonyl Azide-Based Diazo-Transfer Reaction .

    An efficient, standard, mild, and copper-free imidazole-1-sulfonyl azide hydrochloride-based diazo-transfer method was implemented in a set of four resins that cover a broad range of hydrophobicity. The imidazole-1-sulfonyl azide hydrochloride is easily prepared/commercially available, stable upon storage at 4 °C, and proved to be a suitable alternative to triflyl azide for diazo-transfer .
