Acetyl tributyl citrate (made by reaction of tributyl citrate and acetic anhydride)

Process description: The reaction of tributyl citrate and acetic anhydride produces the main product acetyl tributyl citrate. For this purpose, the process consumes acetic anhydride, hydrochloric acid, and tributyl citrate. Utilities consumed comprise thermal energy, electricity, unspecific inorganic chemical, cement, and disposal of cement. Acetic acid is produced as by-product. Utility demands in form of thermal energy and electricity are estimated according to the chemical park in Gendorf. For each kg of chemical product, 1.2 MJ electricity and 2 MJ thermal energy are required. A conversion rate of 95% is assumed. Process wastes are treated in municipal waste incinerators. Dataset type is technology-specific (simplified extension layer). Allocation type is allocation via price. In case of energy co-production, allocation via avoided burden is applied for the co-produced energy. CAS RN is 77-90-7. All datasets are based on the attributional LCA approach and the methodology defined in the cm.chemicals methodology document.
