Title:
フルオロヨードアルカン類の製造プロセスで使用する触媒の前処理及び再生方法
Document Type and Number:
Japanese Patent JP5788961
Kind Code:
B2
Abstract:
A process for the preparation of a fluoroiodoalkane represented by the structural formula CF3(CF2)n—I, wherein n is 0 or 1. The process has the step of reacting a source of iodine with a compound represented by the structural formula CF3(CF2)n—Y, wherein Y is selected from H, Cl, Br and COOH and wherein n is 0 or 1. The reaction is carried out at a temperature from about 100° C. to about 750° C. and at a pressure from about 0.001 to about 100 atm for a contact time from about 0.001 second to about 300 hours in the presence a catalyst. The catalyst is subject to one or both of the following: (a) treating the catalyst prior to the reaction via contact with a gas selected from the group consisting of hydrogen fluoride, trifluoromethane, hydrogen, hydrogen iodide, iodine, fluorine, and oxygen, wherein the contact is carried out at a temperature and for a contact time sufficient to reduce the length of the induction period of the catalyst; and (b) treating the catalyst after the reaction via contact with a gas selected from the group consisting of hydrogen fluoride, hydrogen, fluorine, oxygen, or air at a temperature and for a contact time sufficient to regenerate the catalyst.
