(酯,酰胺,腈类的部分还原)Partial Reduction of Esters, Amides nad Nitriles with Metal Hydride 羰基酸衍生物 →醛 概要 酯,酰胺,腈类在适当的氢化金属还原剂的存在下,低温反应可以还原成醛。经常使用的还原剂有DIBAL、Red-Al等。酯基相对于腈类化合物来说,要被还原后停留在醛的阶段,更加不容易。使用2当量以...
The large volume expansion and self-locking phenomenon of metal hydride particles during hydrogen sorption often leads to a high stress concentration on the walls of a container, which may cause the collapse of the container. In present study, silicone oil was investigated as a glidant for a ...
bicarbonate, sodium sesquicarbonate, sodium borohydride, sodium hydride, lithium aluminum hydride, and the like. The amount of hydrogenation-dehydrogenation agent that may be effective in the invention may range from about 1 to about 100 pptg based on the total amount of the aqueous fluid, ...

Sometimes the heavy metals absorbed by roots and transported to the leaves are converted into non-toxic forms and safety released into the atmosphere, as volatile hydride and methyl compounds. This process is called phytovolatilization and is driven by the evapotranspiration of plants. The plants use...

我们对4个纳米多孔金样品进行了拉伸和压缩试验,这些样品的韧性带尺寸分别为56、149、402和868 nm,所有样品中均没有晶界且韧性带数量相近。我们发现,当韧性带尺寸为402 nm时,拉伸屈服强度大于压缩屈服强度,而韧性带尺寸为868 nm时,拉伸和压缩屈服强度相当。尺寸效应指数-1.18可以很好地描述拉伸屈服强度与韧带尺寸...
