Pyridine (chichibabin synthesis) (made by catalytic conversion of acetaldehyde and formaldehyde)

Process description: The catalytic conversion of acetaldehyde and formaldehyde produces the main product pyridine (chichibabin synthesis). For this purpose, the process consumes caustic soda (50%), ammonia, hydrochloric acid, calcium oxide, titanium dioxide, chromium oxide, formaldehyde, benzene, nitrogen, and acetaldehyde. Utilities consumed comprise cooling water, thermal energy, steam, electricity, unspecific inorganic chemical, cement, and disposal of cement. Dataset type is technology-specific (extension layer). Allocation type is allocation via mass. In case of energy co-production, allocation via avoided burden is applied for the co-produced energy. CAS RN is 110-86-1. All datasets are based on the attributional LCA approach and the methodology defined in the cm.chemicals methodology document.
