Nitrogen History

Nitrogen (Latin nitrogenium, where nitrum (from Greek nitron) means "saltpetre" , and genes means "forming") is formally considered to have been discovered by Daniel Rutherford in 1772, who called it noxious air or fixed air. That there was a fraction of air that did not support combustion was well known to the late 18th century chemist. Nitrogen was also studied at about the same time by Carl Wilhelm Scheele, Henry Cavendish, and Joseph Priestley, who referred to it as burnt air or phlogisticated air. Compounds of nitrogen were known in the Middle Ages.

Nitrogen Specification

The Nitrogen with CAS registry number of 7727-37-9 is also known as Nitrogen gas. The IUPAC name is Molecular nitrogen. It belongs to product categories of Refrigerants; Compressed and Liquefied GasesMicro/Nanoelectronics; Chemical Synthesis; Electronic Chemicals; Gases; Synthetic Reagents; Compressed and Liquefied Gases. Its EINECS registry number is 231-783-9. In addition, the formula is N₂ and the molecular weight is 28.01. Besides, this chemical is a colorless odorless gas and should be sealed in cool, ventilated place away from heat, fire at the temperature below 30 °C. In case of insufficient ventilation wear suitable respiratory equipment.

Physical properties about Nitrogen are: (1)ACD/BCF (pH 5.5): 1; (2)ACD/BCF (pH 7.4): 1; (3)#H bond acceptors: 2; (4)Polar Surface Area: 47.58Å²; (5)Index of Refraction: 1.189; (6)Molar Refractivity: 3.871 cm³; (7)Molar Volume: 31.997 cm³; (8)Polarizability: 1.535×10^-24cm³; (9)Surface Tension: 23.691 dyne/cm; (10)Density: 0.875 g/cm³; (11)Enthalpy of Vaporization: 5.56 kJ/mol; (12)Vapour Pressure: 431351.344 mmHg at 25 °C.

Preparation of Nitrogen: it is prepared by the fractional distillation of liquid air in industry or by mechanical means using gaseous air. The mechanical means needs low-pressure. Firstly, clear the air of dust and mechanical impurities. Then compressing and removing carbon dioxide. Secondly, dried compressed air is separated into oxygen and nitrogen after liquefaction and distillation. At last, compressed nitrogen is filled into bottle.

Uses of Nitrogen. It has a variety of applications, including serving as an inert replacement for air where oxidation is undesirable. It can be used as a modified atmosphere, an inexpensive alternative to argon, a safety measure on top of liquid explosives and it also can be used as a dielectric gas for high-voltage equipment. Besides, it can be used for the manufacturing of stainless steel and used in military aircraft fuel systems to reduce fire hazard. Nitrogen is commonly used during sample preparation procedures for chemical analysis for concentrating and reducing the volume of liquid samples. What's more, nitrogen tanks are also replacing carbon dioxide as the main power source for paintball guns.
