Nitro-glycerin is a fluid of a yellow or brownish colour, having a sp.
On examination it was found to be nitro-glycerin on its way to the mines.
Nitro-glycerin was shaken with a strong aqueous solution of commercial K2S.
The filtrate was clear, and the sulphur bore hammering without the slightest indication of nitro-glycerin.
The nitro-glycerin, which has formed like oil drops, sinks rapidly to the bottom, being specifically the heavier liquid.
Then the nitro-glycerin is in such purity that it may, without danger, be kept any length of time for lecture experiments.
Other experimenters affirm that, instead of free oxygen, nitrous oxide is one of the products of the combustion of nitro-glycerin.
Wurtz advises the nitro-glycerin to be mixed with solutions of nitrate of lime, zinc, or magnesia, the solutions to have a sp.
The nitro-glycerin falls to the bottom of the vessel as an oily-looking liquid, which is washed by decantation.
Since the great explosion at Aspinwall, nitro-glycerin has been the nightmare of Californians.
