2-Ethylhexanol Production from Butyraldehyde
Ethylhexanol Operating Costs & Plant Construction Costs
This report presents the economics of 2-Ethylhexanol (2-EH) production from n-butyraldehyde. The process under analysis dehydrates n-butyraldehyde to obtain 2-ethylpropylacrolein, which is then hydrogenated to form the 2-Ethylhexanol. The economic assessment assumes a plant located in the United States.
The report provides a comprehensive study of Ethylhexanol production and related Ethylhexanol production cost, covering three key aspects: a complete description of the Ethylhexanol production process examined; an in-depth analysis of the related Ethylhexanol plant capital cost (Capex); and an evaluation of the respective Ethylhexanol plant operating costs (Opex).
The Ethylhexanol production process description includes a block flow diagram (BFD), an overview of the industrial site installations, detailing both the process unit and the necessary infrastructure, process consumption figures and comprehensive process flow diagrams (PFD). The Ethylhexanol plant capital cost analysis breaks down the Capex by plant cost (i.e., ISBL, OSBL and Contingency); owner's cost; working capital; and costs incurred during industrial plant commissioning and start-up. The Ethylhexanol plant operating costs analysis covers operating expenses, including variable costs like raw materials and utilities, and fixed costs such as maintenance, labor, and depreciation.

Product
2-Ethylhexanol. 2-Ethylhexanol (also known as 2-EH) is an eight-carbon branched chain alcohol. It is one of the most important oxo alcohols sold in commerce, widely used in the production of emollients and plasticizers. The production on commercial scale of this alcohol is based on the aldol condensation of n-butyraldehyde (n-butanal) and the hydrogenation of the hydroxyaldehyde formed. In fact, 2-EH is commonly produced in integrated complexes based on OXO processes, where n-butanal is first obtained by hydroformylation of propylene, and then converted into the aldol, dehydrated and hydrogenated to 2-ethylhexanol; n-butanol and isobutanol can also be produced.
Raw Materials
Hydrogen. The hydrogen molecule, H2, is the normal state of pure hydrogen, even though hydrogen can be found in its atomic form under specific conditions. It is a very stable molecule, not usually reactive under normal conditions. Essentially, molecular hydrogen is produced industrially by three different methods: hydrocarbons steam reforming, hydrocarbons partial oxidation and water electrolysis. Hydrogen can also be obtained as a by-product recovered in processes such as the manufacture of styrene from ethylbenzene.
n-Butyraldehyde. n-Butyraldehyde is an organic compound used as an intermediate in the production of plasticizers, solvents, and rubber accelerators. It is prized for its ability to undergo further reactions in chemical synthesis. n-Butyraldehyde is produced via the hydroformylation of propylene and stored as a liquid. Its reactivity and use in producing chemicals for plastics and rubber make it valuable to the chemical industry.

2-Ethylhexanol Production from Propylene and Syngas
This report presents the economics of 2-Ethylhexanol (2-EH) production from propylene and syngas located in the United States. Initially, propylene reacts with syngas in a hydroformylation reaction, yielding n-butyraldehyde. This step uses a conventional OXO-alcohol technology. Then, the n-butyraldehyde is submitted to an aldolization, and is subsequently dehydrated to 2-ethylpropylacrolein (EPA). Finally, the EPA is hydrogenated, yielding 2-EH.
