Abstract: 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.

Abstract: A method hydrofluorinates an olefin of the formula: RCX=CYZ to produce a hydrofluoroalkane of formula RCXFCHYZ or RCXHCFYZ, where X, Y, and Z are independently the same or different and are selected from the group consisting of H, F, Cl, Br, and C1-C6 alkyl which is partially or fully substituted with chloro or fluoro or bromo; and R is a C1-C6 alkyl which is unsubstituted or substituted with chloro or fluoro or bromo. The method includes reacting the olefin with HF in the vapor phase, in the presence of SbF5, at a temperature ranging from about −30° C. to about 65° C. and compositions formed by the process.

Abstract: A composite photocatalyst, a photocatalytic filter for air purification, and an air purification device that includes the photocatalytic filter. The composite photocatalyst includes: a first metal oxide particle; and second metal oxide particles arranged on a surface of the first metal oxide particle, wherein specific surface area of the second metal oxide particles is greater than specific surface area of the first metal oxide particle, and bandgap energy of the second metal oxide particles is greater than bandgap energy of the first metal oxide particle. The composite photocatalyst structure may degrade and remove gaseous pollutants under room temperature and atmospheric pressure conditions. The composite photocatalyst may be applied to various indoor and outdoor air purification systems in the form of a photocatalytic filter.

Abstract: This invention is related to the synthesis of organic carbonates from carbon dioxide and epoxides. It is particularly focused on the production of propylene cyclic carbonate from propylene oxide. The proposed catalytic materials includes a support made of aluminum oxyhydroxide (Catapal B®), nitric acid, acetic acid and/or phosphoric acid. An important stage is the physical and chemical conditioning of the catalytic materials and to this end, experimental methodologies such as spheronization and thermal treatments were implemented prior the evaluation process.
