  • Process for the isolation of dodecatrienal and its use as aroma substance
    Patent number: 8212082
    Abstract: The present invention relates to a process for preparing at least one compound with Z?1 cycles and 7 to 16 carbon atoms with at least one aldehyde group, at least comprising the stages: (a1) oxidation of a composition (A), at least comprising a cyclic olefin with Z cycles and 7 to 16 carbon atoms and at least two C—C double bonds, by means of dinitrogen monoxide to give a composition (A1), (a2) separating off the at least one cyclic olefin with Z cycles and 7 to 16 carbon atoms with at least two C—C double bonds from the composition (A1) from stage (a1) in order to obtain a composition (A2), (b1) separating off the at least one cyclic compound with Z cycles and 7 to 16 carbon atoms with a keto group from the composition (A2) from step (a2), in order to obtain a composition (B1), comprising at least 50% by weight of the at least one compound with Z?1 cycles and 7 to 16 carbon atoms with at least one aldehyde group and at least two C—C double bonds, where Z may be 1, 2, 3 or 4.

  • Process for preparing pure cyclododecanone
    Patent number: 8188320
    Abstract: The present invention relates to a process for preparing at least one cyclic compound with Z cycles and 7 to 16 carbon atoms with a keto group, at least comprising the stages: (a1) oxidation of a composition (A), at least comprising one cyclic olefin with Z cycles and 7 to 16 carbon atoms and at least two C—C double bonds, by means of dinitrogen monoxide to give a composition (A1), (a2) separating off the at least one cyclic olefin with Z cycles and 7 to 16 carbon atoms with at least two C—C double bonds from the composition (A1) in order to obtain a composition (A2), and (b) distillative treatment of the composition (A2) from step (a2) in order to obtain a composition (B), comprising the at least one cyclic compound with Z cycles and 7 to 16 carbon atoms with a keto group and less than 1.0% by weight of the at least one compound with Z?1 cycles and 7 to 16 carbon atoms with at least one aldehyde group, where Z can be 1, 2, 3 or 4.

  • PROCESS FOR THE PREPARATION OF POLYETHEROLS FROM ALKYLENE OXIDES
    Publication number: 20120130134
    Abstract: A process for the preparation of polyetherols, comprising the following steps: a) reaction of at least one starter compound with at least one alkylene oxide and a catalyst to give a crude polyetherol and b) removal of low molecular weight byproducts from the crude polyetherol from step a), wherein the crude polyetherol is treated with a stripping gas in a column having internals.
