Description
本發明係有關於一種氫化方法,且特別是有關於一種苯多羧酸或其衍生物之氫化方法。
氫化反應是石油化學工業常見的反應,通常藉由觸媒幫助氫化反應,觸媒主要以過渡金屬元素為主成分。苯多羧酸或其衍生物(例如酯或酐)之氫化反應產物具有許多用途,例如可作為高分子材料的可塑劑或金屬加工的助劑等。
於各種可塑劑中,鄰苯二甲酸二辛酯(dioctyl phthalate,DOP)使用量最多,但由於對於人體與環境不利,因此,其他取代品,例如1,2-環己烷多元酸酯類化合物已被開發研究。
製作1,2-環己烷多元酸酯類化合物最簡單的方式,係將苯多羧酸或其衍生物進行氫化反應,目前業界已提出許多氫化反應的方法。然而,習知之氫化反應皆需於高壓下(50~200巴(Bar))進行反應,且需要一定的高壓氫氣,苯環的氫化率才能提高到90%以上,因此,反應設備的價格不斐,進而使反應成本無法降低。
因此,本發明提出一種苯多羧酸或其衍生物之氫化反應,此種氫化反應係於低壓下進行反應,不但可達到高產率(yield),且能降低製程成本。

於一實施例中,苯多羧酸衍生物例如鄰苯二甲酸二乙酯(Diethyl phthalate,DEP)。
於另一實施例中,苯多羧酸衍生物例如鄰苯二甲酸二丁酯(Dibutyl phthalate,DBP)。
於又一實施例中,苯多羧酸衍生物例如鄰苯二甲酸二異辛酯(diisooctyl phthalate,DOP)。
於再一實施例中,苯多羧酸衍生物例如鄰苯二甲酸二異壬酯(diisononyl phthalate,DINP)。
之後,將苯多羧酸或其衍生物置於反應器中,以進行氫化反應,反應器可以是連續式(例如滴流床反應器(trickle bed reactor))或非連續式(例如批次反應器(batchwise))。

此外,於觸媒中尚包括助劑,例如活性碳(activated carbon)、碳化矽(silicon carbide)、氧化鋁(aluminum oxide)、二氧化矽(silicon dioxide)、二氧化鈦(titanium dioxide)或上述之組合。
再者,亦可添加成型劑(forming agent)於觸媒中,成型劑例如鋁膠(alumina sol)、矽膠(silica gel)、鈦膠(Titanium sol)、鋯膠(zirconium sol)或瀝青(pitch),成型劑之作用在於使觸媒載體成型(如柱狀)。

此外,氫化反應中可添加溶劑(用於幫助苯多羧酸或其衍生物之溶解)於反應器中,亦可不添加溶劑於反應器中,以避免溶劑移除的問題。
相較於習知於高壓(50~200巴(Bar))條件下進行氫化反應,本發明之觸媒與製程,可使氫化反應在常壓下或較低壓力的條件下進行(小於50巴(Bar)),且反應產率(yield)仍可高達99%以上,且實驗操作條件較容易控制,進而可降低製程成本。
