    摘要:

    本文通過(guò)茚蟲威中間體催化加氫合成反應(yīng)用鈀炭催化劑的性能對(duì)比，考察了鈀炭催化劑的載體和載體預(yù)處理對(duì)催化劑性能的影響。實(shí)驗(yàn)結(jié)果表明：硝酸超聲回流處理活性炭可以有效地去除活性炭中的雜質(zhì)灰分，減小雜質(zhì)對(duì)催化劑性能的影響；選擇平均孔徑大和比表面積高的活性炭為Pd/C催化劑載體可以獲得較好的催化反應(yīng)活性和選擇性。

    Abstract:

    Comparing the catalysts’ performance of palladium on carbon applied in the catalytic hydrogenation synthesis of indoxacarb intermediate, the effects of the carriers of catalysts and pretreatment were investigated in this paper. The results showed that nitric acid reflux treatment with ultrasound can effectively remove the ash of activated carbon and reduce the impact of those impurities on properties of catalysts. And in the catalytic reaction of indoxacarb intermediate, the Pd/C catalyst on activated carbon with large average pore size and high specific surface area exhibited better catalytic reactivity and selectivity.
