Abstract: The object of the present invention is a method for the purifying distillation of raw, aqueous 1,4-butanediol (1), in which 1,4-butanediol (5) freed of components boiling at a lower point than 1,4-butanediol and water is conducted through three distillation columns (III, IV, V), components boiling at a higher point than 1,4-butanediol are drawn from the bottom of the first column and conducted to the third (7), 1,4-butanediol is conducted from the top of the first column (6) into the second, the bottom product of the second column (9) is conducted into the third, the top product of the third column (11) is returned at least partially to the first column, characterized in that the pure 1,4-butanediol is removed from the side outlet of the second column.

Abstract: The invention relates to a method for purifying a composition (I) containing at least one cyclic ketone having 7 to 16 C atoms. The method encompasses the thermal treatment of the composition (I) with a catalyst containing at least one transition metal and the further purification by a method selected from the group consisting of destillation, extraction and crystallization. The invention also relates to a method for producing cyclododecanone, which includes a purification of this type, and to the use of at least one catalyst containing at least one transition metal for purifying a composition (I) containing at least one cyclic ketone having 7 to 16 C atoms by thermal treatment of the composition (I) with a catalyst that contains at least one transition metal.

Abstract: The invention relates to a method for purifying 1,4-butynediol, in which 1,4-butynediol is processed in a dynamic mixing device in an inert gas atmosphere at 25 to 150 °C at a velocity gradient exceeding 100,000 sec-1 in the radial play between the rotor and the stator, one waits for the phases to separate at temperatures ranging from 25 to 150 °C, and the bottom phase is eliminated. Also disclosed is a method for hydrogenating 1,4-butynediol into 1,4-butenediol and 1,4-butanediol with the aid of the purified 1,4-butynediol.
