羰基還原
英文
carbonyl reduction-
Diazaspiro [ 4. 4 ] nonane was synthesized from malononitrile as the starting material by a series of nucleleophilic displacement, hydrolytic cyclization and carbonyl reduction
摘要以丙二腈為原料，經過親核取代、水解環合、羰基還原系列反應，合成了2 ， 7 -二氮螺[ 4 . 4 ]壬烷。Carbonyl groups readily attach themselves to nickel or cobalt atoms, but not so strongly that they cannot link to other molecules and jump ship to form larger molecules
羰基很容易與鎳或鈷原子結合，可是鍵結並不強，因此它還是可以與其他分子結合，甚至跳船形成更大的分子。The borohydride reducing reagent supported by the strong acid cation exchange resin was prepared by the strong acid cation exchange resin reacting with sodium borohydride. the reductive ability of the resin reducing the carbonyl compounds is strong, so the yields are generally pretty high ( 51 % ？
用強酸型離子交換樹脂與硼氫化鈉作用制備了強酸型離子交換樹脂支載的硼氫化還原劑.探討了在不同溶劑中制備的還原樹脂的還原能力；應用於還原羰基化合物時有良好的產率（ 51 % ？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
