Dioctyl adipate (made by esterification of adipic acid and 2-ethylhexanol)

Process description: The esterification of adipic acid and 2-ethylhexanol produces the main product dioctyl adipate. For this purpose, the process consumes caustic soda (50%), hydrochloric acid, activated carbon, 2-ethylhexanol, and adipic acid. Utilities consumed comprise cooling water, steam, electricity, inert gas, process water, unspecific inorganic chemical, cement, and disposal of cement. Dataset type is technology-specific (extension layer). Allocation type is no allocation needed in this unit process. In case of energy co-production, allocation via avoided burden is applied for the co-produced energy. CAS RN is 123-79-5. All datasets are based on the attributional LCA approach and the methodology defined in the cm.chemicals methodology document.
