Benzyl cyanide (made by reaction of benzyl chloride and sodium cyanide)

Process description: The reaction of benzyl chloride and sodium cyanide produces the main product benzyl cyanide. For this purpose, the process consumes hydrochloric acid, benzyl chloride, ammonia, caustic soda (50%), sodium cyanide, calcium oxide, titanium dioxide, and chromium oxide. Utilities consumed comprise thermal energy, electricity, unspecific inorganic chemical, cement, and disposal of cement. Sodium chloride 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 140-29-4. All datasets are based on the attributional LCA approach and the methodology defined in the cm.chemicals methodology document.
