Process development for the synthesis of saturated branched fatty derivatives: Homogeneous and heterogeneous catalysis in miniplant scale

Beschreibung

Saturated branched fatty derivatives find application in the lubricant and cosmetic industry due to the decisive advantages in temperature and viscosity behavior compared to their linear homologues. Thus, finding new synthesis routes, particularly based on renewable resources, is of great industrial interest. This work covers a new synthesis route for production of such saturated branched derivatives based on linoleic methyl ester. The developed process combines homogeneously rhodium catalyzed co-oligomerization of linoleic methyl ester with ethene and heterogeneously catalyzed hydrogenation of the co-oligomers in miniplant scale. Final step within the process development is the extraction of the homogeneous rhodium catalyst.
