§荨之中亦以使用苯作為芳香族化合物、使用丙_作為 製造異Θ苯的反應於工業上為最重要的。此時,苯與兩 嗣之莫耳比(笨/丙酮)以1〜20為佳。若低於上述範圍,則二 、 本一異丙基苯的生成量有變大之傾向。二異丙基 苯一/、丙基苯在異丙苯步驟中,經由與苯的轉烷基化而可 月b恢復成異丙笨,但轉烷基化為反應溫度高,若 剩餘的二異 丙基本、三異丙基苯的份量多,則蒸氣費用增大且有時不經 _ «λ·» 右而於上述範圍,則以反應器的後步驟回收過剩的 本寺因為對蒸餾塔造成負荷,故有時不經濟。 本發明之芳香族化合物與_的反應,係以氫共存下進行為 099107954 12 201038512 其特徵。此處所謂之氫,可為分子狀的氫氣,亦可為反應條 件下發生氫之由環己烷等烴類所發生的氫。丙酮與苯與氫反 應時,原理上,氫若與丙酮等莫耳以上即可,由分離回收方 面而言,適當範圍為相對於丙酮,以卜刈倍莫耳、較佳為 • 1〜30倍莫耳。欲將丙_轉換率抑制於未滿1〇〇%時,將所用 之氫1由1倍莫耳減低即可因應。又,於本發明反應中供給 的氫’與丙酮所具有的氧原子反應變成水並伴隨異丙苯可由 〇 反應器出口取出。又,丙酮當量以上的氳只要不進行不欲的 副反應,於本質上不被消耗。 對於反應系統添加氫氣之情況’通常連續供給,但並非特 別限定於此綠,亦可妓顧科添加氫氣餅止反射

重量比若小,則無法充分進行烷基化反應,異丙苯等之烷基 化芳香族化合物的產率降低,故有時不經濟。又,剩餘之固 體酸物質的重量比若大’則丙酮的轉換率降低,其有時亦不 經濟。 於本發明之燒基化芳香族化合物之製造方法中,經由上述 含銀觸媒之作用,㈣被氫化生成醇後,該醇、與芳香族化合 物’經由固舰物質的仙而魏基化成為絲化芳香族化 合物。即’本發明之製造方法+,階段性引起氫化及院基化。 本發明中反應形式為固定床反應之情況,固體酸物質與上 述含銀觸媒之填充方法有時對反應成績造成大影響。如上 述,本發明中氫化與燒基化為階段性引起。因此,根據反應 099107954 201038512 各階段依序填充適當的觸媒種’以有效率使用觸媒的音義 和抑制非目的之副反應的意義為佳。 特別為了提高反應速度而增大氫壓和溫度之情況,於— 的化學反應中經常看見引起低氫壓和低反應溫度所未見 般 之 不佳的副反應舉動,於此種情況中,觸媒的填充方法特別對 於反應成績有造成大影響的可能性。 , 作為根據反應之各階段依序填充適當觸媒種的方法,可列 Ο 舉例如,(1)將固體酸物質及上述含銀觸媒均勻混合、填充 之方法、(2)將上述含銀觸媒的濃度由觸媒層的上游側往下 游側以一定比例減少,同時將固體酸物質的濃度由上游側往 下游側以一定比例增大般填充的方法、(3)填充载持上述2
