Description
Summary:The reaction of methanol with hydriodic acid to produce methyl iodide was studied as a step of the CIS Process. The yield of methyl iodide increased with increasing iodine concentration. Following methyl iodide formation and activity decrease of hydriodic acid, dimethyl ether was formed by the reaction of methyl iodide and methanol. The dimethyl ether formation was accelerated by iodine. The co-existence of iodine and sulfuric acid caused no other side reactions. The separation of methyl iodide from the reaction mixture by distillation was discussed briefly.
