Oxygen nitrogen mixed with

It must be remembered that nitrogen when mixed with oxygen (that is, as in air) is nontoxic, but when oxygen is not present it will cause suffocation. Any entry into a reactor that has been filled with nitrogen must be fully flushed with air. Only people who are licensed to enter enclosed vessels and are wearing the correct respiratory gear, with qualified backup, may enter the vessel.

I62 Selective oxidation of hydrocarbons is a known method to produce alcohols. However, the alcohols react with the oxygen to produce aldehydes, and the latter react with oxygen to produee organie aeids. A 50mol/s stream consisting of 90% efliane and 10% nitrogen is mixed with a... 

Consider the combination of nitric oxide and oxygen. Nitric oxide (a colorless gas) when mixed with oxygen gas (also colorless) becomes reddish-brown. The color is identical to that of another gas, nitrogen dioxide. All the properties of the nitric oxide-oxygen mixture are consistent with the conclusion that the gas nitrogen dioxide has... 

A procedure involving catalytic oxidation of sulphones has also been developed218. In this case the sulphone is mixed with sodium carbonate and cobalt(II) oxide and the mixture is burned in a stream of oxygen. This method works very well for nitrogen-containing sulphones and requires no expensive equipment. 

The metal ion, e.g. Fe or Co, when in its lower oxidation state can share electron charge with the oxygen molecule adduct. Several iron and cobalt prophyrin derivatives and cobalt-Schiff bases show the necessary reversibility and rates for successful application [e.g. 23]. a, a, a", a" -weso-tetrakis[(o-piralamidophenyl)-po phinato] Co (II) has been complexed with 1-methylimidazole to make a complex (CoPIm) which, when mixed with polybutyl methacrylate gave oxygen permeabilities on the order of 10-9 sec-cm/(cm2-s-cmHg) with a selectivity of about 5 over nitrogen [23].
