Description
1328010 玫、發明說明: 【發明所屬之技術領域】 本發明係關於一種製備單氫全氟烷化物,雙(全氟烷基) 亞膦酸鹽及全氟烷基膦酸鹽之方法,其包括在一種適合反 應介質内至少一進行以至少一種鹼處理至少一種全氟烷基 磷炫之步驟。 【先前技術】
已知單氫全氟烷化物有一段時間了,且已發現其在各種 領域上具有廣泛用途,特別為可作為臭氧親和性致冷劑 (WO 01/40400, WO 01/23494, WO 01/23491 « WO 99/36485, WO 98/08913),作為清潔劑(WO 01/32323),作 為微電子領域之蝕刻劑組份(US 2001/0005637, US 6228775),滅火劑應用(WO 01/05468,Combust. Flame, 121, No. 3 (2000),第 471-487 頁,CN 1218702),作為發泡體中之 發泡劑(US 6225365,W0 01/18098)及聚合物材料與有效麻 醉劑之製備(Anesth. Analg (N.Y.),79,No· 2(1994),第 245-251 頁,Τ· Hudlicky等人,J. of Fluorine Chem.,59,No. 1(1992),第 9-14 頁)。 在商業上很容易以噸規模製備部份這些單氫全氟烷烴, 例如,五氟乙烷,通常係藉由氯化烴之催化氫氟化反應進 行該製法(WO 01/77048, EP 1052235)。該方法之缺點為首 先存在有於相當高溫下使用氟化氫所產生之危險。而且, 該方法需要特殊觸媒,其必需事先藉由比較複雜的方法製 成。該方法的另一項缺點為使用氣製備該氣化烴之方法在 84146 1328010 生態上仍有爭議,且該製備支出會進一步增加。最後,製 備該五氟乙烷之已知方法並不很適用於製備長鏈單氫全氟 炫烴,例如,一氫九氟丁炫·。
而且,已知有一些其它方法,其中係使用下述特殊氟化 劑製備五氟乙烷,這些特殊氟化劑包括,例如,BrF3(R.A. Devis,J. Org. Chem. 32(1967),第 3478 頁),XeF2(JP 2000/119201),SF4(G. Siegemund,Liebigs Ann. Chem·,1979, 第 1280頁,E.R. Bissell,J. of Organic Chem·,29,(1964)第 1591),SbF5(G.G. Belenkii等人,Izv· Akad. Nauk SSSR,Ser. Khim.,1972,第 983 頁,Chem. Abstr. 77(1972) 75296,A.F. Ermolov 等人,Zh Org. Khim·,17(1981),第 2239 頁,J. Org· Chem. USSR (Engl. Translation),17 (1981),第 199頁,US 2426172),MoF6(L.D. Shustov等人,Zh.Obshch. Khim.,53 (1983),第 103 頁,J. Gen. Chem. USSR (Engl, translation), 53 (1983),第 85 頁)及 CoF3(US 6162955)。
然而,上述方法並沒有受到工業上的重視,因為該個別 起始化合物及該氟化劑本身很昂貴。 反之,已知只有少數幾種可用以製備長鏈單氫全氟烷烴 之方法。 根據一種最早的方法’可藉由強鹼(例如,乙氧基鈉)處 理,使全氟化羧酸之鹽(J.D. LaZerte等人,J. Am. Chem. Soc., 75 (1953),第 4525 頁;R.N. Haszeldine,J. Chem. Soc. 1953, 第 1548 頁)或對應酯(E. Bergman,J. 〇rg. chem·,23 (1958), 第476頁)進行去羧基化反應以製備該單全氟烷烴。 84146 1328010 根據另—種方法,可藉由以水性驗處s全敦化酮(其在該 羰基之碳原子上具有三氟甲基)以製備單氫全氟烷烴(lv Saloutina等人,ιζν· Akad Nauk SSSR,^ 第 $ 期,第1114-1116頁,(:116111.八1)价.101 (1984) 210504\)。該方 法之缺點亦為必需使用昂貴的起始物質及高溫。 此外’尚可於南溫下藉由呈氣相之氫(歐洲專利Ερ 632 〇〇1)使用各種還原劑(例如,鋅灰)在甲醇(丁 HudHcky等人,j 〇fF1U〇rineChem.,59,第 1期(1992),第 9-14頁),甲氧基鈉 (J. L. Howell等人,j. 0f Flu〇rine Chem,72,第^“州), 第61-68頁)中,藉助於該複合物[7&(:口2((:;21^)扣(1)乩15旧561 等人,Polyhedron 17,第 7期(1998),第 1037-1043 頁)使全氟 丁基碘進行還原反應製成該 1H-正-九氟丁院。 然而這些方法之缺點同樣為必需先使用該起始化合物 全氟丁基碘進行反應,但是該全氟丁基碘只能藉由比較昂 貴的製法製成。 【發明内容】 因此本發明目的為提供一種可以以簡單並費用不高的 方法製備良好產率的單氫全氟烷烴。較佳應該以高純度得 到該單氫全氟烷烴,本發明另一目標為製備雙(全氟烷基) 亞膦酸鹽及全氟烷基膦酸鹽。 【實施方式】 已藉由根據本發明製備該通SCnHF2n+1(其中較佳 為1 ^η^4)之單氫全氟烷烴,雙(全氟烷基)亞膦酸鹽及全氟烷 基膦酸鹽之方法達成該目標,該方法包括一種適合反應介 84146-990107.doc 1328010 質内’至少進行以至少一種鹼處理至少一種全氟烷基磷烷 之步驟。 根據本發明,於各情況中,可以使用一種全氟烷基磷烷 或二或更多種全氟烷基磷烷之混合物進行根據本發明製備 該單氫全氟烷烴之方法。 可藉由熟悉本技藝者已知之習用方法製備根據本發明該 方法所使用之該全氟烷基磷烷。
如 V. Ya. Semenii 等人在 Zh. Obschch. Khim·,55,第 12 期 (1985),第 2716-2720 頁中所述,及 ν· Ignative 在 J. 〇f Fluorine Chem·,103 (2000),第 57-61 頁中所述及 WO 00/21969所述,可較佳藉由適合起始化合物之電化學氟化反 應’製備該全氟烷基磷烷。這些資料之對應說明文併於本 文供參考並可視為本揭示内容的一部份。 在根據本發明方法之一項較佳具體實例中,可利用至少 一種以下通式I之全氟烷基磷烷 (CnF2n+1)mPF5.m
