This is a technical design project I conducted during my final year of undergraduate study, on the production of Chlorobenzene from direct chlorination of Benzene. I would like to acknowledge the influence of my supervisor for this project in person of Dr. O.J Odejobi (Chemical engineering dept. Obafemi Awolowo University, Ile-Ife), his knowledge & tutelage of the course helped in the success of the project. ABSTRACT Chlorobenzene is an aromatic organic compound with the chemical formula C6H5Cl. It is characterized by its colorless, flammable liquid form, major application has been found for it as a common solvent and a widely used intermediate in the manufacture of other chemicals in the industries. A proposed process design for the establishment of a production plant with the capacity to produce 20,000 ton/year of MonochloroBenzene together with not less than 2000 ton/year of dichlorobenzene by direct chlorination of benzene (continuous process).
