Abstract: The invention relates to a continuously operated process for the purification by distillation of the oxirane formed in the oxirane synthesis by reaction of a hydroperoxide with an organic compound, wherein the crude oxirane is separated in a dividing wall column into low-, intermediate- and high-boiling fractions and the oxirane is taken off as intermediate boiler at the side offtake in a concentration of at least 99.9%.

Abstract: The invention relates to a continuous method of purification by distillation of 1,2-propylene glycol that accumulates as a by-product during the synthesi s of propylene oxide. Said method is characterised in that the mixture that is produced during said synthesis, which contains the 1,2-propylene glycol, is separated in a dividing wall column into a low-boiler, medium-boiler and hig h- boiler fraction and that 1,2-propylene glycol is drawn off laterally from th e column as a medium boiler.

Abstract: The invention relates to a method for the continuous purification by distillation of methanol, used as a solvent in the synthesis of propylene oxide by the reaction of a hydroperoxide with propylene, with the simultaneo us isolation of the methoxy propanols as an azeotropic mixture with water, in addition to the low and high boilers. Said method is characterised in that t he solvent mixture that accumulates during the synthesis is separated in a dividing wall column.

Abstract: The invention relates to a method for producing monoisopropylamine (MIPA). According to the inventive method, propine and/or propadiene are reacted with MIPA under hydroamination conditions. The hydroamination product(s) obtained are then reacted with ammonia under transalkylation and hydrogenation conditions.
