高年級必修化學鍵、過渡金屬化學、醇,醚與羰基化合物、酉安,芳烴與雜環、化學動力學、分子光譜學等與低年級相應之延續科目,而有關的實驗課則注重近代化學技術。Abstract : the allylation reactions of hydrates of - keto aldehydes and glyoxylates by diallyltin dibromo were carried out in water to give - keto and - ester homoallylic alcohols in good to excellent yields
文摘:在水相中, -羰基水合醛及水合醛酯與二溴二烯丙基錫作用可較高產率地生成-羰基和-酯基高烯丙基醇Alcohols, ethers, and carbonyl compounds
醇、醚與羰基化合物Deactivation of ni - la ac catalyst for vapor phase methanol carbonylation
甲醇氣相羰基化催化劑失活行為的研究Promotion effect of v on cuo al2o3 catalyst for methanol synthesis from co2 hydrogenation
催化劑上甲醇羰基化性能的影響It is known that the presence of a solvent has a significant effect on the rate of reaction
結合以上內容及一些學者和作者在一些溶劑中的甲醇羰基化實驗。Nonpolar solvent with little dielectric constant has good effect to the rate of the reaction, while larger polar solvent without h ( superscript + ) also can increase the rate of the reaction
可以知道對甲醇羰基化這一反應,在極性溶劑中,極性較大且為非質子型的溶濟能顯著提高反應的速率;非極性溶劑中,介電常數較小的溶劑能增加反應速率。Acid gas removal from synthesis gas ( ammonia, methanol and oxo reaction ). coal gas natural gas oil field gas and refinery gas, and chemical engineering technique affairs
合成氣(氨、甲醇及羰基) 、煤制氣、天然氣、油田氣、煉廠氣中酸性氣體的脫除,及化學工程技術業務。Nevertheless, the step toward the practical application has not been developed as fast as had been expected. mainly, there are some problems, such as low electrocatalytic activity of the anodic catalyst, the poisoning of the anode catalysts by the adsorbed carbonyl species derived from methanol oxidation, methanol permeation from anode to cathode and demand for methanol - tolerant oxygen reduction catalyst
然而,陽極催化劑的低催化活性、甲醇氧化中間體羰基物對陽極催化劑的毒化、甲醇從陽極向陰極的滲透、以及由甲醇滲透引起的陰極氧還原抗甲醇要求等,致使dmfc的實際應用發展速度一直沒有預期的快。分享友人
