HYDROGEN IODIDE MANUFACTURING METHOD AND HYDROGEN IODIDE MANUFACTURING APPARATUS |
摘要 |
A hydrogen iodide manufacturing method which includes a step of producing aqueous solution of hydrogen iodide and sulfuric acid by causing iodine-containing aqueous solution and sulfur dioxide to react with each other in a pressurized condition. The pressurized condition may be of not lower than 0.1 MPa in gauge pressure. The method may further include: a separation step of adding iodine to the aqueous solution of hydrogen iodide and separating an upper phase containing sulfuric acid relatively to a large extent and a lower phase containing hydrogen iodide relatively to a large extent; and a step of producing hydrogen iodide by adding sulfur dioxide to the upper phase in a pressurized condition and extracting the produced hydrogen iodide to the lower phase.
