    Abstract: Disclosed is a process for the liquid phase hydrogenation of phthalates to cyclohexanoates. By using a reactor with a multiplicity of tubes, with a cooling fluid supplied to the outside of the tubes, shortcomings of traditional recycle mode fixed bed reactors can be overcome. Feed dilution can be avoided, resulting in much higher reaction rates.
