  • Publication number: 20220340508
    Abstract: A process produces sodium and/or potassium alkoxides in countercurrent by reactive rectification. Alcohol is reacted in countercurrent with the respective alkali metal hydroxide. The vapours containing alcohol and water are separated into at least two serially arranged rectification columns. The energy of the vapour obtained in the first rectification is utilized for operating the second rectification. This specific energy integration coupled with establishing a certain pressure difference in the two rectification stages makes it possible to cover a particularly large proportion of the energy required for the rectification through electricity and to save heating steam.

  • Patent number: 11332421
    Abstract: The present invention relates to a process for oligomerization of C2- to C8-olefins in at least two reaction stages, wherein in the last distillation column the reaction mixture is fractionated such that only very small amounts of the reactant olefins and the analogous alkanes remain in the bottom of the distillation column.

  • Patent number: 11254631
    Abstract: The present invention relates to a process for oligomerization of C2- to C8-olefins in at least two reaction stages, wherein in the last distillation column the reaction mixture is fractionated such that only very small amounts of the oligomers formed remain in the distillate.

  • Patent number: 11186782
    Abstract: The invention relates to a catalyst for a process for removing mercaptans and optionally disulfides (if present) from hydrocarbon streams, in particular C4 streams, in the presence of higher dienes, in particular C5 dienes. At the same time, the invention also relates to a process for removing mercaptans and disulfides (if present) from hydrocarbon streams, in particular C4 streams, in one embodiment in the presence of 1-butene, by thioetherification of the mercaptans with polyunsaturated hydrocarbons, wherein the process is carried out in a reactor with addition of hydrogen in the presence of higher dienes, in particular C5 dienes.
