【正文】 P，廣泛用于塑料、橡膠、油漆及乳化劑等工業(yè)中。 與二丁酯（ DBP）相比，DOP 的揮發(fā)度只有 DBP 的 1/20；與水的互溶性低，并有良好的電性能， 但也有其不足點(diǎn)，其在熱穩(wěn)定性、耐遷移性、耐寒性和衛(wèi)生性方面稍差。 關(guān)鍵詞 ： DOP 異 辛醇 苯酐 工藝設(shè)計(jì) 工藝計(jì)算 設(shè)備選型 Abstract Dioctyl phthalate ,referred to as DOP, Molecular Formula: C24H38O4 .It is important to generalpurpose plasticizer and has bee the largest amount used of plasticizerthe at home and abroad, now it is widely used in rubber, plastics and pharmaceutical industry, plays an important role in the national economy. After analysis and parison of various raw materials, synthesis, the design process is the use of multitank reactors in series continuous esterification 3 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.
