Abstract
Disclosed is a process for the preparation of hydrogen iodide, lithium iodide and methyl iodide by the reaction under anhydrous conditions of hydrogen and iodine in a non-alcoholic solvent using a homogeneous rhodium catalyst. Lithium iodide and/or methyl iodide are obtained by including lithium acetate and/or methyl acetate in the reaction medium.
Claims4
Process for the preparation of hydrogen iodide which comprises reacting under anhydrous conditions hydrogen and iodine at a temperature of about 80.degree. to 200.degree. C. and a hydrogen pressure of at least 15 psig in a non-alcoholic, organic solvent in the presence of a homogeneous rhodium catalyst, the rhodium catalyst being the result of a rhodium compound contacting an iodine compound in the presence of carbon monoxide.
