2-Propylheptanol Production from Valeraldehyde
2-Propylheptanol Plant Capital & Operating Cost Analysis | United States | Q1 2026
This report presents the economics of 2-Propylheptanol (2-PH) production from valeraldehyde (aka pentanal). This process involves two main steps: aldolization of valeraldehyde to Propyl-2-heptenal; hydrogenation of Propyl-2-heptenal to 2-PH, which is then submitted to a fractional distillation for separation of both light and heavy impurities.
The report provides a comprehensive study of 2-Propylheptanol production and related 2-Propylheptanol production cost, covering three key aspects: a complete description of the 2-Propylheptanol production process examined; an in-depth analysis of the related 2-Propylheptanol plant capital cost (Capex); and an evaluation of the respective 2-Propylheptanol plant operating costs (Opex).
The 2-Propylheptanol 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 2-Propylheptanol 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 2-Propylheptanol 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-Propylheptanol. 2-Propylheptanol (a.k.a. 2-PH, 2-Propylheptyl alcohol) is a branched fatty alcohol, primarily used in the production of plasticizers and surfactants applied in detergents or industrial cleaning agents, and in the manufacture of lubricants and acrylates in adhesives applications. This fatty alcohol is produced on a commercial scale mainly by OXO synthesis, followed by aldol condensation and hydrogenation steps.
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.
Valeraldehyde. Valeraldehyde is an organic compound used as a flavoring agent and as an intermediate in the production of plasticizers, rubber chemicals, and pharmaceuticals. Valeraldehyde is produced via the oxidation of pentanol and is stored as a liquid. Its reactivity and role in chemical synthesis make it valuable in various industrial processes.

2-Propylheptanol Production from Butenes and Syngas
This report presents the economics of 2-Propylheptanol (2-PH) production from butenes and syngas located in the United States. Initially, butenes react with syngas in a hydroformylation reaction, yielding n-valeraldehyde. This step uses a conventional OXO-alcohol technology. Then, the valeraldehyde is submitted to an aldolization, forming 2-Propyl-2-heptenal and water. Finally, the 2-Propyl-2-heptenal is hydrogenated, yielding 2-PH.
