Abstract
A process for the formation of perfluoroalkylethyl alcohols from perfluoroalkylethyl iodides is disclosed. The process involves treatment of the perfluoroalkylethyl iodide with oleum.
Claims4
A process for converting 2-perfluoroalkylethyl iodide to 2-perfluoroalkylethyl alcohol comprising contacting 2-perfluoroalkylethyl iodide with oleum of a strength sufficient to provide a mole ratio of SO.sub.3 to 2-perfluoroalkylethyl iodide of from about 2 to 1 to about 10 to 1 at about 50.degree. C. to 130.degree. C. to produce 2-perfluoroalkylethylsulfate, contacting the 2-perfluoroalkylethylsulfate with enough water to bring the SO.sub.3 content to below 30% calculated as sulfuric acid and an oxidant of sufficient strength to produce 2-perfluoroalkylethylalcohol while minimizing the production of 2-perfluoroalkylethyl iodide.
