鈀碳性質(zhì)、用途與生產(chǎn)工藝，作用鈀碳是一種催化劑，是把金屬鈀粉負(fù)載到活性碳上制成的，主要作用是對(duì)不飽和烴或CO的催化氫化。具有加氫還原性高、選擇性好、性能穩(wěn)定、使用時(shí)投料比小、可反復(fù)套用、易于回收等特點(diǎn)。用于石油化工、醫(yī)藥工業(yè)、電子工業(yè)、香料工業(yè)、染料工業(yè)和其他精細(xì)化工的加氫還原精制過程。分類及用途鈀碳（Pd/C）催化劑是將活性組分鈀通過某種方式負(fù)載于載體活性炭上所制備的一種負(fù)載型催化劑。盡管ChemicalbookPd具有良好的催化性能，但是對(duì)于塊狀鈀或海綿鈀來說，其機(jī)械性能差，熱穩(wěn)定性差，且價(jià)格較為昂貴，不適合直接用于催化反應(yīng)。因此人們利用具有一定機(jī)械強(qiáng)度的、較高比表面積的、適宜化學(xué)性質(zhì)的載體對(duì)Pd進(jìn)行支撐和分散，使上述問題得到了解決?；钚蕴恳?yàn)槠涓弑缺砻娣e、較好的熱穩(wěn)定性和機(jī)械強(qiáng)度，被用作制備鈀碳（Pd/C）催化劑的載體。Pd/C催化劑具有均相催化劑所不具有的一些優(yōu)勢(shì)，因而得到了的研究和應(yīng)用。

style="text-indent:25px">傳統(tǒng)的萃取分離法主要是采用與水互不相溶的有機(jī)溶劑作萃取溶劑，有的反應(yīng)速度慢，傳質(zhì)速率低，分配比較小而需要在振蕩器上進(jìn)行較長(zhǎng)時(shí)間振蕩或多次萃取才能達(dá)到定量萃取的目的。均相萃取、異相分離萃取體系可以克服異相萃取分離技術(shù)中的一些缺點(diǎn)而受到重視。本文以乙醇為萃取溶劑，均相萃取、異相分離Pd(II)。試驗(yàn)表明liusuan銨存在下乙醇與水分相過程中，鈀(II)與碘負(fù)離子開成的二階碘化鈀負(fù)離子與質(zhì)子化乙醇形成電中性的締合物乙醇與二階碘化鈀負(fù)離子被乙醇相萃取，能使鈀(II)從鐵(III)、鋁(III)、鋅(II)、錳(II)、錫(II)、鉻(III)、鈷(II)的混合溶液中分離。該體系萃取分離鈀，與傳統(tǒng)的鹽酸-(β-巰基氫化肉桂酸異戊酯)-苯體系和liusuan-(β-巰基-β-苯丙酰苯)-三氯甲烷體系相比，具有不使用youdu溶劑、試劑用量少、分離成本低、分離迅速、操作簡(jiǎn)便等優(yōu)點(diǎn)。</p><p style="text-indent:25px">傳統(tǒng)的低鈀合金回收方法是先將廢料用硝酸溶解后經(jīng)趕硝趕酸后加氨水轉(zhuǎn)化鈀，再加鹽酸將鈀沉淀，反復(fù)3次后還原得純鈀粉。其工藝中氨水轉(zhuǎn)化體積很大，過濾困難，加鹽酸酸沉銀后溶液中鈀鹽溶解量較大，特別是對(duì)低鈀合金或含銅、鋅等廢料，鈀碳回收率很低，約為80%。而這種新的回收工藝方法較傳統(tǒng)工藝所沒有的優(yōu)點(diǎn)，新的工藝過程簡(jiǎn)單，消耗時(shí)間短，不需要浪費(fèi)大量溶液的趕硝過程，將鈀轉(zhuǎn)化為水合氧化鈀有效富集后，使得試劑消耗降低，省略了氯化銀洗滌過程，提高鈀直收率；避免了銅、鎳等賤金屬對(duì)氨水的消耗量，節(jié)約氨水80%，降低了成本；這種新工藝中將鈀鹽洗液調(diào)pH值后還原得粗鈀粉，與鈀銅粉共同進(jìn)行鈀二次回收，獲得較高的回收率。鈀用途這么多?有多少項(xiàng)是你不知道的?</p><div
