    Abstract: Verfahren zur Herstellung von C 4 - bis C 13 -Monohydroxyverbindungen aus einer Sumpffraktion, die bei der Destillation eines Rohgemisches von C 4 - bis C 13 -Oxoaldehyden aus der kobalt- oder rhodiumkatalysierten Hydroformylierung, oder bei der Destillation eines Rohgemisches von C 4 - bis C 13 -Oxoalkoholen, dadurch gekennzeichnet, dass die Sumpffraktion in Anwesenheit von Wasserstoff mit einem Katalysator, enthaltend Kupferoxid und Aluminiumoxid, bei einer Temperatur von 150 °C bis 300 °C und einem Druck von 20 bar bis 300 bar in Kontakt gebracht wird, das erhaltene rohe Hydrierprodukt einer Destillation unterzogen wird und dass die Menge an C 4 - bis C 13 -Monohydroxyverbindungen, die nach der Hydrierung im rohen Hydrierprodukt enthalten ist, größer ist als die Menge an C 4 - bis C 13 -Monohydroxyverbindungen, die sich aus der Hydrierung der in der Sumpffraktion enthaltenen Ester- und Aldehydverbindungen stöchiometrisch ergibt, einschließlich der in der Sumpffraktion vor der Hydrierung noch enthaltenen C 4 - bis C 13 -Monohydroxyverbindungen.

    Abstract: The present invention is in the field of etching metal- or semimetal-containing materials by atomic layer etching. In particular the present invention relates to a process for etching a metal- or semimetal-containing material comprising bringing a metal- or semimetal-containing material having an activated surface in contact with an organic compound containing a leaving group which is capable of forming a volatile compound upon coming in contact with the metal- or semi- metal-containing material and a group which is capable of coordinating to a metal or semimetal atom in the metal- or semimetal-containing material.

    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 Cu n+, 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 Cu 2+ : Cu + in the liquid melt increases, obtaining a liquid melt having an increased molar ratio Cu 2+ : 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 (Cl 2 ) is formed, wherein Cl 2 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.
