    摘要： The invention relates to a process for preparation of chlorine from hydrogen chloride comprising circulating a liquid melt comprising copper ions Cun+ with n being a number in the range from 1 to 2, alkali cations and chloride ions Cl in a reactor system comprising three bubble lift reactors I, II and III, each comprising a reaction zone i, ii and iii respectively, wherein: ⋅(a) in the reaction zone i of the first bubble lift reactor I, a liquid melt comprising copper ions Cun+, alkali cations and chloride ions Cl— is contacted with oxygen at a temperature in the range from 395 to 405° C. so that the molar ratio Cun+:Cu+ in the liquid melt increases, obtaining a liquid melt having an increased molar ratio Cun+:Cu+ ⋅(b) the liquid melt obtained in (a) is circulated to the reaction zone ii in the second bubble lift reactor II, where the liquid melt is contacted with hydrogen chloride at a temperature in the range from 395 to 405° C. so that water is formed, obtaining a liquid melt being enriched in chloride anions (CI-) compared to the liquid melt obtained according to (a); ⋅(c) circulating the liquid melt obtained in (b) to the reaction zone iii in the third bubble lift reactor III, which is operated at a temperature in the range from 420 to 430° C. so that chlorine (Cl2) is formed, wherein Cl2 is removed from the reaction zone iii and the third bubble lift reactor III respectively in gaseous form, leaving a liquid melt depleted of Cl-compared to the liquid melt obtained according to (b). The invention further relates to a reactor system comprising three bubble lift reactors I, II and III.

    摘要： Provided is a method for continuously producing a cyclic carbonate, by which generation of a glycol in a reaction for synthesizing a cyclic carbonate is suppressed, and a cyclic carbonate having a high purity can be efficiently obtained even by simple purification.A method for continuously producing a cyclic carbonate, including filling a catalyst in a fixed-bed tube reactor, and continuously feeding carbon dioxide and an epoxide to the fixed-bed tube reactor to thereby bringing the carbon dioxide and the epoxide into contact with the catalyst, while continuously withdrawing the reaction liquid in the fixed-bed tube reactor, wherein the method includes a pre-treatment step in which a pre-treatment liquid containing a cyclic carbonate is brought into contact with the catalyst before feeding the carbon dioxide and the epoxide to the fixed-bed tube reactor, and the generated glycol is removed out of the system.
