Question

Discuss a nitrogen line for reactions under inert atmosphere – operation of a pressure regulator at the nitrogen cylinder.

Answer 1

vaccum /inert gas manifold systems ,commonly called Schlenk lines, are ideal for handling compounds that react with O2 ,water, or Co2 . their design allows compounds to be handled and reactions to be performed under an inert atmosphere of argon or nitrogen

gas pressure regulators Nitrogen excellent conductivity,anti-corrosive,unmatched quality,chemical resistance and durability . a typical cylinder, about 5' tall, can hold about 230 cubic feet of nitrogen gas , if it is filled to the maximum operating pressure which can be in the range of 2200 psi, that is to say,if it is full. the cyllinder will have the maximum allowable pressure stamped on the side near the value

EXAMPLE[A 180 liter may hold 140 cubic meter at 10 bar. the disadvantage of liquid nitrogen is that it is a perishable commodity. it will vaporize and escape from the dewars over a short period of time.

It is nonflammable and it will not support combustion . nitrogen gas is slightly lighter than air and slightly soluble in water . it is commonly thought of and used as an inert gas,but it is not truely inert. it forms nitric oxide and nitrogen dioxide with oxygen, ammonia with hydrogen, nitrogen sulphide with sulfur

The term inert means chemically inactive ;so an inert atmosphere is an environment in which power bed fusion can take place without the risk of communication from reactive gases that exist in the air,such as oxygen and carbon dioxide
