Abstract: PROCESS FOR SEPARATING TRIETHANOLAMINE CONTINUOUSLY BY DISTILLATION FROM A MIXTURE OF MONOETHANOLAMINE, DIETHANOLAMINE AND TRIETHANOLAMINE TOGETHER WITH ETHANOLAMINE ETHERS AND WATER OBTAINED BY REACTION OF AMMONIA WITH ETHYLENE OXIDE IN THE LIQUID PHASE UNDER SUPERATMOSPHERIC PRESSURE AND AT ELEVATED TEMPERATURE, IN WHICH THE MIXTURE IS DISTILLED IN TWO STAGES. THE LOW-BOILING FRACTION AND THE HIGH-BOILING FRACTION ARE TAKEN OFF AND DISCHARGED IN THE FIRST STAGE AND THE INTERMEDIATE-BOILING FRACTION COMPRISING > 99.4% BY WEIGHT OF TRIETHANOLAMINE AND

Abstract: The invention concerns a process for preparing phthalides of general formula (I), in which R , R , R and R , independently of each other, designate hydrogen, C1-C4 alkyl or C1-C4 alkoxy, by the hydrogenation of phthalic acid anhydrides of general formula (II), in which the groups R , R , R and R have the above meanings, by means of hydrogenating catalysts. Hydrogenation is carried out by means of nickel catalysts doped with metals of the first, sixth and/or seventh subgroup of the periodic system.
