"hydrogen chloride by-product in traditional chlorination processes recovered and recycled in safer manner... more energy efficient electrolysis generating hydrogen and chlorine... can be handled more safely in its anhydrous (water-free) state...  safely bound to triethylmethylammonium chloride salt creating bichloride ionic liquid under ambient conditions and later safely released... bichloride also used to manufacture plastics or silicones"
