    Abstract: Distillation column has a dividing wall which divides it into inflow and extraction sections, and upper and lower column zones. The mixture for distillation comprises a vapor feed which enters between the upper and lower inflow sections, between which the side extraction point removes vapor. The inflow and the extraction zones are offset relative too the dividing wall. The vapor feed rate is equal in all zones of the column. The distillation column has a dividing wall (TW) which divides it into an inflow section (2,4), an extraction section (3,5), and common upper (1) and lower (6) column zones. The mixture for distillation is at least partially a vapor feed (F) which enters between the upper and lower inflow sections, and the side extraction point (B) removes vapor between the upper and lower extraction zones. The cross sectional surfaces of the inflow and the extraction zones are set by an offset in the dividing wall. The F-factor is equal in all the zones of the column, defined as the product of the gas flow speed in m/seconds multiplied with the square root of the gas density in kg/m3.

    Abstract: The invention relates to a method for producing alkyne diols by reacting ketones with acetylenic hydrocarbons in an organic solvent in the presence o f a base which contains potassium alcoholates of primary and/or secondary alcohols. The alkyne diols are produced while forming adducts which precipitate out of the reaction mixture and which are comprised of alkyne monoalcohols and/or alkyne diols and a base. The stoichiometries of the reaction partners are selected such that gelatinous adducts are formed which comprise a spherical surface, whereby the reaction mixture remains agitable during the entire reaction.
