Abstract: Production of ethanolamines comprises reacting ammonia with ethylene oxide in the presence of water in a pressurized reactive distillation column equipped with a reboiler. The energy supply to the reboiler and the ammonia:ethylene oxide ratio in the feed stream are controlled so that the bottoms stream can be separated into an ammonia and water stream and a mono-, di- and triethanolamine stream. Production of mono-, di- and triethanolamine comprises liquid-phase reaction of ammonia with ethylene oxide in the presence of water in a pressurized reactive distillation column (I) equipped with a reboiler, where the mono:di:triethanolamine ratio is controlled by the energy supply to the reboiler and the ammonia content of the bottoms stream is controlled by the ammonia:ethylene oxide ratio in the feed stream so that the bottoms stream can be separated into an ammonia and water stream and a mono-, di- and triethanolamine stream in a single distillation column (II).

Abstract: On-spec phthalic anhydride is prepared by distillative purification of crude phthalic anhydride by a process in which crude phthalic anhydride is fed to a distillation column which is operated at reduced pressure, the low boilers are removed at the top or in the vicinity of the top of the distillation column and the on-spec phthalic anhydride is removed from the column via a side take-off.

Abstract: Production of phthalic anhydride involves the distillation of crude PA under reduced pressure. Production of phthalic anhydride (PA) which complies with specifications involves the distillation of crude PA under reduced pressure in a column from which the volatiles are taken off at or near the top of the column and the pure PA is taken off at a side arm.

Abstract: Disclosed is a method for the distillative purification of aqueous raw dimethylacetamide (raw DMAc) containing DMAc as well as low-boiling and high-boiling components. According to the inventive method, the low-boiling and high-boiling components are eliminated in one column or several columns that are mounted in series so as to obtain pure DMAc. The disclosed method is characterized in that the pure DMAc is withdrawn from the single column or the last of several columns as a liquid side stream.
