After analysis and parison of various raw materials, synthesis, the design process is the use of multitank reactors in series continuous esterification technology, the catalyst is alumina with a 1:1 ratio of Sn catalyst pound annual output of 100,000 tons Dioctyl phthalate, to meet domestic demand. The design follows the mature technology, advanced technology, equipment configuration scientific, environmental safety, economic efficiency, the principle of reciprocity. After paring domestic and foreign advanced production methods, process and equipment configuration , the choices are starting from phthalic anhydride and isooctanol after esterification, de alcohol, refined by product line production process octyl phthalate. Design for production process design argument, the design of facilities and process selection, with a flow chart with control points, the main production equipment and size chart, workshop equipment configuration diagram. The last part is about environmental protection and labor safety, in order to achieve reduction of the three wastes emissions, strengthen the three wastes treatment, to ensure safe production purposes.
