This compound can be synthesized by oxo reaction. One of the steps in the oxo reaction is consecutive hydrogenation reaction of the 2-ethyl-2-hexenal to 2-ethyl-hexanol. This reaction requires nickel-based catalyst as an effective step for obtaining higher and purer 2-ethyl-hexanol yields. This research aims to develop the formula and procedure of catalyst synthesized in Laboratory of Catalysis and Reaction Engineering Institut Teknologi Bandung and get a rate of the reaction. The catalysts were synthesized by co-impregnation with a nickel content of 20%-w and varied with molybdenum loading (5-20%). The support that used for these metals is alumina-phosphate (AlP2). The synthesized catalysts were tested for their activity against the 2-ethyl-2-hexenal conversion at 120°C, 30 bar in the fixed bed reactor and compared its performance with a commercial catalyst. The results showed the addition of molybdenum loading increases selectivity of 2-ethyl-hexanol but decrease the conversion of 2-ethyl-2-hexenal. The highest selectivity was achieved by Ni5-Mo20/AlP2 (X=31%, S=85%), but the highest conversion was achieved by Ni20/AlP2 (X=88%, S=32%). Nickel tend to play a part of breaking the C=C bond. Meanwhile, molybdenum tends to break the C=O bond. This shows that the hydrogenation of C = C bonds and the C = O bond is very depending on nickel and molybdenum metal loading.[/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Author keywords” size=”size-sm” text_align=”text-left”][vc_column_text][/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Indexed keywords” size=”size-sm” text_align=”text-left”][vc_column_text]2- Ethyl-Hexanol,Hydrogenation,Nickel Catalyst[/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Funding details” size=”size-sm” text_align=”text-left”][vc_column_text][/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”DOI” size=”size-sm” text_align=”text-left”][vc_column_text]https://doi.org/10.14419/ijet.v7i4.15319[/vc_column_text][/vc_column_inner][vc_column_inner width=”1/4″][vc_column_text]Widget Plumx[/vc_column_text][/vc_column_inner][/vc_row_inner][/vc_column][/vc_row][vc_row][vc_column][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][/vc_column][/vc_row]
