Provided is a method for producing hydrogen chloride that makes it possible to produce hydrogen chloride efficiently using simple equipment. Hydrogen chloride is produced using a method that comprises: an electrolysis step in which chlorine and hydrogen are obtained by electrolyzing an inorganic chloride aqueous solution having a pH of 3-5, inclusive; a reaction step in which crude hydrogen is obtained by reacting the chlorine and hydrogen obtained in the electrolysis step at 1000-1500 °C, inclusive, using an excessive quantity of hydrogen in terms of molar ratio relative to chlorine; a dehydration step in which the crude hydrogen obtained in the reaction step is dehydrated; and a distillation step in which the dehydrated crude hydrogen obtained in the dehydration step is compressed and liquefied and the liquid crude hydrogen is refined through distillation. |
