A process for producing a bismuth dithiocarbamate or dithiophosphorate by the reaction of a bismuth hydroxide, bismuth oxide or bismuth oxynitrate with a dithiocarbamate or a dithiophosphoric acid. The bismuth dithiocarbamates and dithiophosphorates exhibit very good EP and antiwear properties and are useful in lubricant formulations.

Process for preparing isononylamines starting out from 2-ethylhexanol, characterized in that (a) 2-ethylhexanol is dehydrated in the presence of a catalyst to form octene; (b) the octene obtained in step a) is reacted with carbon monoxide and hydrogen in the presence of a transition metal compound of group VIII of the Periodic Table of the Elements to form isononanal; and (c) the isononanal obtained in step b) is converted into isononylamines.
