Title:
PREPARATION OF PERFLUOROALKYL IODIDE
Document Type and Number:
Japanese Patent JPS5951225
Kind Code:
A
Abstract:

PURPOSE: To prepare the titled substance, by reacting iodine with iodine pentafluoride and a fluoroolefin in the presence of a catalyst such as P, Sb, Mo, W, or their compounds using a specific amount of heptafluoroisopropyl iodide as a diluent.

CONSTITUTION: The titled substance can be prepared by reacting iodine with iodine pentafluoride and a fluoroolefin (e.g. tetrafluoroethylene) in the presence of a catalyst selected from P, Sb, Mo, W and their compounds using 0.5W 5pts.wt., based on 1pt.wt. of iodine pentafluoride, of heptafluoroisopropyl iodide as a diluent. The amount of the catalyst is about 0.006W0.04mol per 1mol of iodine pentafluoride, and the reaction is carried out at 40W80°C under atmospheric or relatively low pressure.

EFFECT: It is not necessary to preheat the reaction system at a high temperature, and the reaction heat can be removed effectively, accordingly, the rate of reaction can be increased.
