<p align="justify"> <br /> <br /> 2-ethylhexanol is saturated alcohol compound that used in petrochemical and polimer industry. In synthesize route of 2-EH, there is hydrogenation step of EPA via 2-ethylhexanal to 2-EH. In this research, hydrogenation of 2-ethyl-2-hexenal to produce its corresponding alcohol with nickel catalyst was studied. Catalyst that have been developed are nickel/alumina catalyst with metal loading between 40% and 60% with promoter copper, zinc, and molybdenum. Peptization method is used to synthesize catalyst with boehmite and nickel(II)nitrate hexahydrate as metal source. Impregnation method used for the addition of the promoter. BET (Brunauer-Emmett-Teller), XRD (X-ray Diffraction), and TPR (Temperature-Programed Reduction) used to acquire physical data, and composition along with the hydrogen consumption for catalyst activation. Catalyst activity test have done in isothermal batch reactor at 120oC and 30 bar for 10 hours. Every 1-hour, reaction mixture analyzed using gas chromatography with FID detector and RTX-5 column. <br /> <br /> Catalyst that synthesized have surface area around 61,5 – 235,2 m2/g, pore diameter around 76.4 Å, and pore volume around 0.19 ml/g. Catalyst with best activity achieved by 53% nickel loading catalyst give 100% conversion and 81% selectivity to 2-ethylhexanol. The test result also shows that copper is the best promoter to increase hydrogenation activity of C=O bond. This result also streghtened by kinetic modeling using power law. <br /> <p align="justify">
