selectivity of catalyst 中文意思是什麼

selectivity of catalyst 解釋
催化劑的選擇性
  • selectivity : n. 1. 選擇；精選。2. 【無線電】選擇性；選擇度；【物理學】選擇能力；選擇率。
  • of : OF ＝Old French 古法語。
  • catalyst : n. 【化學】觸媒，催化劑，接觸劑〈又作 catalytic agent〉；〈比喻〉觸發因素，〈口語〉（善用熱情、言語等打動他人的）有感染力的人。
  1. We would like to measure the intrinsic selectivity behavior of a catalyst independent of any potential disguises.

    我們很想去掉任何可能的假象以測定催化劑固有選擇性的可能。
  2. Cyanopyridine, intermediate of rimifon, was synthesized from 4 - picoline using vanadium oxide as a catalyst in fixed - bed reactor, reached 99 % conversion of 4 - picoline, 88 % selectivity and 87. 12 % yield of 4 - cyanopyridine

    以4 -甲基吡啶為原料，在固定床反應器中通過含氧化釩的催化劑發生氣固相接觸氨氧化反應制備雷米封中間體4 -氰基吡啶， 4 -甲基吡啶的轉化率為99 % ， 4 -氰基吡啶的選擇性為88 % ，收率為87 . 12 % 。
  3. This process relies on a catalyst of high selectivity and weak activity.

    這過程所靠的是一種高選擇性和低活性的催化劑。
  4. Conversion and selectivity of catalytic reactions as well as the deactivation rate of the catalyst itself is very temperature-sensitive.

    催化反應的轉化率和選擇性以及催化劑本身的失活速率均對溫度十分敏感。
  5. Studied the liquid - phase synthesis of butyl acetate from n - butyl alcohol and acetic acid using the supported heteropoly blue as catalyst. examed several factors imposing on esterification. the results revealed : using this catalyst, the reactions conversion percentage reaches nearly 100 %, product yield is 98. 9 %, selectivity is 98. 9 %. reusing it 10 times, the efficiency is still well. in addition, using this catalyst, the reactions temperature is mild, the reaction time is short and the equipment hasnt any erosion. furthermore, there is no “ threewastesdischarge

    對以負載型雜多藍為催化劑的乙酸與正丁醇的液相酯化反應進行了研究.考察了影響酯化反應的因素.結果表明：以負載型雜多藍為催化劑，酯化反應轉化率接近100 % ，收率可達98 . 9 % ，選擇性為98 . 9 % ，重復使用10次催化效果仍好.該催化劑還有反應條件溫和、反應時間短、對設備無腐蝕、無三廢排放等優點
  6. The results showed the bentonite is an efficient catalyst with cheapness, non - corrosivity, high selectivity, mild reaction conditions and less contamination, ease of set - up and work - up
