Abstract

Abstract: Chlorine plays a central role for the industrial production of numerous materials with global relevance. More recently, polychlorides have been evolved from an area of academic interest to a research topic with enormous industrial potential. In this minireview, the value of trichlorides for chlorine storage and chlorination reactions are outlined. Particularly, the inexpensive ionic liquid [NEt3 Me][Cl3 ] shows a similar and sometimes even advantageous reactivity compared to chlorine gas, while offering a superior safety profile. Used as a chlorine storage, [NEt3 Me][Cl3 ] could help to overcome the current limitations of storing and transporting chlorine in larger quantities. Thus, trichlorides could become a key technique for the flexibilization of the chlorine production enabling an exploitation of renewable, yet fluctuating, electrical energy. As the loaded storage, [NEt3 Me][Cl3 ], is a proven chlorination reagent, it could directly be employed for downstream processes, paving the path to a more practical and safer chlorine industry. Abstract : Chlorine is an indispensable base chemical that is used to produce numerous materials. To enable the chlorine industry to harvest renewable energies, a safe chlorine storage is of central importance. More recently, trichlorides, [Cl3 ] −, have evolved to a key technique for the storage of chlorine and for important chlorination reactions. In this minireview, the potential of trichlorides for academic research and the chlorine industry are outlined.
