4-nitrobenzoyl chloride (made by reaction of 4-nitrobenzoic acid and thionyl chloride)

Process description: The reaction of 4-nitrobenzoic acid and thionyl chloride produces the main product 4-nitrobenzoyl chloride. For this purpose, the process consumes hydrochloric acid, ammonia, caustic soda (50%), calcium oxide, thionyl chloride, titanium dioxide, chromium oxide, and 4-nitrobenzoic acid. Utilities consumed comprise thermal energy, electricity, unspecific inorganic chemical, cement, and disposal of cement. By-products comprise hydrogen chloride and sulfur dioxide. 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 122-04-3. All datasets are based on the attributional LCA approach and the methodology defined in the cm.chemicals methodology document. Data quality flag: Methodology - the EF contains a positive (rather than negative) value for biogenic CO2 removals as the production method avoids the burden of carbon capture in the supply chain.
