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 C-olefins having a terminal double bond comprised in the olefin-comprising feed used and of the linear C-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.

The present invention relates to a process for the pretreatment of hydroamination catalysts, wherein the hydroamination catalyst is brought into contact with an ammonia-comprising mixture before the reaction of olefins with ammonia, a primary or secondary amine, with the ammonia-comprising mixture comprising less than 40% by weight of olefin The invention further relates to a process for preparing alkylamines by reaction of olefins with ammonia, primary or secondary amines over a hydroamination catalyst, wherein the hydroamination catalyst is pretreated according to the invention before the reaction of the olefins by bringing the hydroamination catalyst into contact with an ammonia-comprising mixture comprising less than 40% by weight of olefin.

Method for pre-treating hydroamination catalysts

A process for preparing a primary amine with a tertiary alpha-carbon atom by reacting a tertiary alcohol with ammonia in the presence of a heterogeneous catalyst, by performing the reaction in the presence of a non-microporous, non-zeolitic aluminosilicate as a catalyst, where the aluminosilicate has a molar Al/Si ratio in the range from 0.1 to 30.
