Abstract: The present invention relates to a process for preparing hydroformylation products of olefins having at least four carbon atoms, in which a high proportion of both the linear Ci-olefins having a terminal double bond comprised in the olefin-comprising feed used and of the linear Ci-olefins having an internal double bond is converted into hydroformylation products. Furthermore, the invention relates to a process for preparing 2-propylheptanol which comprises such a hydroformylation process.

Abstract: La presente invención se refiere a un método para la producción de productos de hidroformilación a partir de olefinas que tienen al menos cuatro átomos de carbono. Una cantidad alta de las olefinas lineales de Ci con enlaces dobles terminales que están presentes en la admisión que comprende las olefinas, y también de las olefinas lineales de Ci que tienen enlaces dobles internos se convierten en productos de hidroformilación. La invención se refiere además a un método para la producción de 2-propilheptanol, que comprende dicho método de hidroformilación.

Abstract: In a process for co-oligomerization of olefins, an olefin starting material comprising olefins with n carbon atoms and olefins with 2n carbon atoms is converted over an olefin oligomerization catalyst to a reaction product. The process is performed under such conditions that the conversion of olefins with 2n carbon atoms is less than 10%. Both the co-oligomer with 3n carbon atoms and the olefin with 2n carbon atoms removed from the reaction product have a high hydroformylatability.

Abstract: The present invention relates to a process for separating at least one propylene glycol from a mixture (M) comprising water and said propylene glycol, said process comprising (I) evaporating the mixture in at least two evaporation and/or distillation stages at decreasing operating pressures of the evaporators and/or distillation columns obtaining mixture (M′) and mixture (M″); (II) separating the mixture (M′) obtained in (I) in at least one further distillation step, obtaining a mixture (M-I) comprising at least 70 wt.-% of water and a mixture (M-II) comprising less than 30 wt.-% of water.
