标 题 :Process for regenerating noble metal catalyst for the synthesis of hydrogen peroxide according to the anthraquinone process
发明人：SCHREYER GERD; THEISSEN FERDINAND; WEIBERG OTTO; WEIGERT WOLFGANG
权利人:DEGUSSA
摘要:In situ regeneration of noble metal catalysts for the synthesis of hydrogen peroxide by the anthraquinone process is provided by employing as the working solution coming from the extraction or desorption step and being introduced into the hydrogenation step a solution which contains at least 250 mg/liter of hydrogen peroxide, to thereby completely regenerate the noble metal catalyst by full capacity of the hydrogenation step.

标 题 :Catalyst and process for the synthesis of saturated carboxylic esters
发明人：CASTANET YVES; LEGRAND CHRISTOPHE; MORTREUX ANDRE; PETIT FRANCIS
权利人:ATOCHEM
摘要:Saturated carboxylic esters are produced from alkyl formate and an olefin, without the presence of substantial amounts of carbon monoxide, at a temperature of 120 DEG to 280 DEG C., under a pressure of 1 to 3,000 bars, in the presence of a catalyst based on ruthenium coordinated by ligands selected from carbon monoxide, halogen atoms and amines, and in the presence of an amide as a solvent. The catalyst is selected from catalysts consisting essentially of RuCl3.3H2O; catalysts consisting essentially of the combination of an RuCl3.3H2O together with at least one stabilizer selected from iodine, covalent iodides and quaternary ammonium halides; catalysts comprising Ru3(CO)12 together with at least one stabilizer such as is mentioned above; and catalysts selected from RuI3, [RuCl2(CO)3]2, Ru(NH3)6Cl3 and [Ru(NH3)5Cl]Cl2, comprising, where appropriate, in addition, at least one stabilizer such as is mentioned above.
