| 專利名稱 | Method for the preparation of 2, 2, 3, 4, 4, 4-hexafluoro-1-butanol | | 專利證號 | US6740786B1 | | 國別 | 美國 | | 獲證日期 | 2004-05-25 | | 專利摘要 | The method for preparing 2,2,3,4,4,4-hexafluoro-1-butanol includes reacting methanol and hexafluoropropene in the presence of a free radical initiator such as di-isopropyl peroxydicarbonate at 25-50° C. and a pressure of 100-300 psi in an autoclave. An inert gas such as nitrogen and argon is added to the autoclave when the pressure is lower than 100 psi in the course of the reaction. | IPC國際分類號 | C07C002932 |
