1359045 九、發明說明: 【發明所屬之技術領域】 本發明相關於製備觸媒製劑之方法及此觸媒製劑之用 途。 【先前技術】 固體觸媒常使用於製備聚酯類。舉例來說,此種觸媒 可為二氧化鈦或由二氧化鈦衍生之化合物。例如,Ep 0736560描述包含鹼金屬鈦酸鹽或鹼土金屬鈦酸鹽之觸 媒。 肌 於異相觸媒作用下,觸媒並未溶解於反應媒質中,而 疋以各別之固相存在。在觸媒作用之一種變化中,觸媒仍 以各別之固相保留於系統中。在一些情況下,舉例說明, 如醋化程序之觸媒作用中,觸媒係以粉體加入,然而,於 反應過私中浴解其中。於此處,發生一個從異相至均相觸 媒作用之連續轉換。 觸媒在反應媒質中之分佈顯著地影響反應的過程。 原則上,將粉體型態異相觸媒提供至反應媒質中是可 行的。然而,尤其於連續程序中,除粉體的不佳計量性之 缺點外,此方法在將觸媒迅速分佈於反應媒質方面尚有不 足。因此,先前技術慣於使用觸媒在液體中的糊漿。 由於觸媒顆粒於觸媒糊漿存放時很容易沈降,故於使 用前必須攪動此糊漿,否則觸媒計量將因此不夠精確。 史托克定律說明沈積速率v係觸媒球體直徑d之平方 與固液間密度差Δρ成正比,而與懸浮液之黏度^成反 比: (史托克定律) ^pg 18η 由方程式中as i 間沈降,但前楹:易見的,所有的觸媒顆粒必然隨著時 動。 疋顆粒之沈降速率大於它們的熱(布朗)運 作用:L力之外’凡得瓦吸引力’也為熟知之分散力,也 於顆粒上。如未藉由穩定力對抗,例如一相似的靜電 如二聚合物,則分散力導致於粒子間發生絮凝。 "現較大的附聚物,根據史托克定律其 們τ、二:地’尤降。另一方面,絮凝、沈降的系統具有它 們可被容易攪動的優點。 相對的是糊聚之情況,纟中因為觸媒顆粒大小所致而 ’一爭抗絮凝分布範圍外的沈積。&了沈降至難以搜動之緊 挽填充沈積物外,,匕系統的進一步缺點為,它們通常包含 不想要的輔助物質。(聚合潤濕劑和分散劑)。 【發明内容】 本發明之目的在於提供一種製備觸媒製劑之方法,其 中可避免先前技術之缺點,特別是指: -觸媒之過度粗劣分布 -觸媒粉體之不佳計量 -於使用沈積糊漿時觸媒之不佳計量 -觸媒沈積至不能被攪動的結實底部沈積物, 1359045 且其中所得之觸媒·方面不僅於儲存下相當穩定另 面可以發揮最大之觸媒活性。 此目的乃利用一種製備觸媒製劑的方法達成 用分散裝置將含有至少一種在標準狀態下為固體之:機化 &物的觸媒研磨成最大平均粒度吣3為2微米,較佳最大 值為1微米的顆粒,此係根據DIN 66141與〇11^ 661料實 行,然後將其以i至50重量%,較佳為2〇至4〇重量%之 濃度(相對於所完成之觸媒製劑)分散於液體中。該粒度°較 佳以雷射繞射測量。 意外地,在無潤濕劑或分散劑或其他任何穩定懸浮液 的輔助物質之協助下’觸媒可以此方式製備成在靜止狀態 下固化的糊狀物。此糊狀物在達到最小剪應力(即屈服點r 0)後才會開始流動。 觸媒糊狀物之屈服點分別隨著觸媒濃度增加與顆粒粒 度減小而增加。觸媒糊狀物之屈服點可藉由改變觸媒濃度 與粒度做調整。觸媒糊狀物較佳具有23 〇c (室溫)下至少 〇.1Pa ’特較佳為1至30Pa,而最佳為23°C下5至30Pa的 屈服點r 0。屈服點係根據DIN 530 1 9於Z2 DIN圓柱測量 系統(描述於數據表”根據DIN 53019之標準測量系統用數 據’’ ’ Viscolab/Rheolab MC 10,得自 Rhysika MeyS technik GmbH,Stuttgart)中測量且根據賓漢流體計算。為此目的, 將樣品(觸媒糊狀物)裝入Z2標準量測系統中,於此先讓它 於室溫下靜置24小時。在0至1〇〇 1/秒(線性斜面(linear ramp))之切速範圍内,以1 〇〇個測量點進行測量,其中測 1359045 喷射方法之分散設備(例如逆喷射型研磨機)或衝擊流型研 磨機(例如微喷射分散器),以上各例皆可作為分散裝置使 用。攪拌球研磨機則是特佳選擇。 觸媒可於研磨則事先分散或於液體中形成糊漿。針對 可使用冷解器、攪拌器(例如直臂槳攪拌器,蘢型攪 拌器或鑛齒圓盤檀拌器)、Hoesch渦輪機或研磨機 :器具。其後,可利用上述分散裝置之一於液體中使觸媒 達到所欲的粒度。 亩费:某也:广乾式研磨後’然後於溶解器、攪拌器(例如 Ί拌a,籠㈣拌11或㈣圓盤㈣n )、渦輪或 Ystral研磨機t在液體裡形成糊漿。 下述關係通常應用於粒度與觸媒濃度之選擇:粒 小,所選擇的觸媒濃度在指定限制内應該越低,反之亦然。 八1 ::物質較佳以液體各別使用或以混合物使用:水、 二 子之醇類(例如甲醇、乙醇、丙醇(所有显 構物)、丁醇(所右显进仏、 明· I 7有一 碳片早W 醇類’例如含有2至12個 石灭原子的烧二醇類亦 lu 醇…-丁二醇:院…(例如乙二醇、Μ·丙二 萨,, 環己烷二甲醇),羧酸(例如甲酸、乙 酸、丙酸、丁酸、戊酸)或脂肪酸。 ㈠如甲^乙 【實施方式】 根據本發明之太、主 乃疋万去,舉例來說可實 與此有相關限制性): 仃如下(然而,沒有 當觸媒尚未以粉體形態呈現 質磨成粉末,以攪採古β 已知方式將觸媒物 授掉方式混入液體中並事先分散(例如使用 1359045 1毫米)以3000rpm研磨20分鐘和4000rpm研磨50分鐘。 利用篩網(56微米篩目)將此懸浮液從玻璃珠和粗篩分分 離。粒度測量(雷射繞射,Helos)顯示平均粒度d503為0.92 微米,其分佈範圍B90/10為1.5微米。固體含量大約為35 重量%。於80°C下儲存三天後,懸浮液同樣顯示無底部沈 積物形成。將所分散之懸浮液裝入Z2 DIN測量系統並讓 其在室溫下靜置48小時。在〇至1 〇〇 1/秒(線性斜面)之 切速範圍内’以100個測量點進行測量,其中測量時間為 每測量點五秒。懸浮液的剪應力值(起始應力)剩定於 /22.6Pa(根據DIN 53019,Z2 DIN測量,根據賓漢流體叶 算)。 。 【圖式簡單說明】 益 澹” > 【主要元件符號說明】 益
