In-situ FTIR measurements using ReactIR technology proved to be an ideal means for investigating these reactions by tracking the rate of disappearance of the azide IR peak at 2103 cm-1. The kinetics of the cyclopropanations for a number of different catalysts were measured, but the researchers ...
Examples of highly toxic chemicals include:hydrazine, mercuric chloride, osmium tetroxide, white or red phosphorus, sodium azide, and sodium cyanide. The median lethal dose (LD50) for a dangerously toxic chemicals is oral rat LD50 of less than 1 mg/kg of body weight. ...
Correct not absurd, but maybe an absurd selection for the task at hand. Not absurd. Reckless. I'm pretty sure it would work, other than the toxicity factor and the sensitivity to going off, and the latter can probably be dealt with. Lead azide is so not abs...
Table salt - sodium chloride, one of the most common substances occurring in nature - is best classified as what? Why does sodium azide dissolve spontaneously in the water? Why is it not advisable to react an acid with sodium chloride directly? ...
pollucite. One of the world’s richest sources of cesium is located in Bernic Lake Manitoba. It is estimated that about 300,000 metric tons of pollucite ore exists within the lakebed with an average of 20% cesium by weight. Pure cesium can be produced by thermal decay of cesium azide. ...
