Nitrogen cylinder

Normally, N2 is a stable, unreactive molecule, as noted in Chapter 4. However, under the extreme conditions found in an automobile cylinder, nitrogen molecules may react with oxygen molecules to produce nitrogen oxide ... 

Although cylinder nitrogen(II) oxide provides a convenient source for preparations, often it is desirable to obtain the gas quickly in fairly large quantities in the laboratory. The preparation suggested by Blanchard, utilizing the reduction of sodium nitrite by means of iron(II) sulfate, is more diflBcult than the procedure described below, in which sodium nitrite is treated with dilute sulfuric acid. - The product thus obtained is suitable for use in the preparation of such compounds as Fe(NO)2Br, Co(NO)2Br, and [Co(NH3)5(NO)]Cl2. ... 

The ethyl, w-propyl, n-butyl and allyl iodides were commercial products, carefully purified before use, while the other iodides were prepared and purified by standard methods. Cylinder nitrogen was freed from oxygen by passage over sodium at 350°, and cylinder hydrogen was purified by passage through a palladium thimble. Pure nitric oxide was made by the method of Giauque and Johnston.

The liquid air is pumped into the fractionating column. There it is slowly warmed up. The gases boil off one by one, and are collected in tanks or cylinders. Nitrogen boils off first. Can you explain why ...

Cylinders—Nitrogen-compressed gas cylinders come in various sizes and are made of high-strength steel. Equipped and maintained to ensure total safety, they are generally delivered to customers by a distributor using its own trucks. Cylinders are used for relatively low gas consumption requirements. 

The first commercial attempt by Charles S. Bradley and D. R. Lovejoy, relying on power from a newly built Niagara Falls hydrostation, was launched in 1902. Their patented method produced more than 400,000 elongated electric arcs per minute inside a furnace made up of a fixed iron shell surrounded by a rapidly revolving cylinder. Nitrogen oxide generated from the passing air enriched with O2 was converted to nitric acid, but the operation was uneconomical and their Atmospheric Products Company folded in 1904. ...
