Abstract: A method for the N-alkylation of amines by reacting alcohol with (di)alkylamine in the presence of hydrogen is carried out in the presence of a catalyst based on copper and magnesium silicate, which contains 0-2 wt.% each of barium oxide, chromium (III) oxide (Cr2O3) and/or zinc oxide. Also claimed is the use of this catalyst for N-alkylation of amines.

Abstract: The invention concerns a process for preparing phthalides of general formula (I), in which R , R , R and R , independently of one another, designate hydrogen, C1-C4 alkyl or C1-C4 alkoxy, by hydrogenating phthalic acid anhydrides of general formula (II), in which the groups R , R , R and R have the above meanings, with hydrogen in the presence of suspended Raney-type catalysts in a hydrogenating device by mixing a liquid phase containing the catalyst and the phthalic acid anhydride used and the resultant phthalide and a gaseous phase containing the hydrogenating hydrogen using a mixing device which has a mixing output of at least 50 W/l in the liquid phase
