Nitric oxide, corrosion

Salpeter-frass, m. corrosion by niter, -gas, n. nitrous oxide nitric oxide. [Pg.376]

Nitric oxide (NO) is severely irritating to eyes and respiratory system. Effects may be delayed for several hours following exposure. Corrosive. Inhalation may result in chemical pneumonitis and pulmonary edema. Nonflammable. Oxidizer. This product accelerates the combustion of combustible material. [Pg.63]

Stability Stable. Reacts vigorously with fluorine, fluorine oxides, and chlorine in the presence of moisture. Nitric oxide is non-corrosive and may be used with most common structural materials. However, in the presence of moisture and oxygen, corrosive conditions will develop as a result of the formation of nitric and nitrous acids. [Pg.64]

H. Corrosion resistant materials of construction would be specified, but external corrosion is possible due to nitric oxide fumes, allow minimum factor = 0.1. [Pg.381]

Nitric oxide gas is moderately toxic. Exposure can cause severe irritation of the eyes, nose, and throat. Chronic inhalation produces pulmonary edema, irritation of the respiratory tract and corrosion of teeth. [Pg.644]

Boiling muriatic acid quickly changes calomel into corrosive sublimate and metallic mercury. In hot nitric acid It dissolves, evolving nitric oxide. [Pg.583]

A motor pump is not recommended because the nitric oxide is apt to cause corrosion. If too high a vacuum is used at first, a residue of ethyl iso-nitrosomalonate may remain. [Pg.28]

The initial pressure was 5 kg per cm2. The carbon monoxide was condensed in a trap cooled with liquid nitrogen, whence it was evaporated into a bomb at a pressure of 1-2 kg per cm2. Air was then admitted from a container bringing the pressure up to 5 kg per cm2. The explosion products were collected in a glass flask in which the nitric oxide content was determined as usual. Control experiments showed that a delay in transferring the explosion products to the flask reduced the yield of nitric oxide in a geometrical progression by 10% per minute. This was apparently due to corrosion and in succeeding experiments the time of transfer did not exceed one minute. [Pg.374]

Biocorrosion in well-oxygenated cooling systems can also involve other types of bacteria, such as nitrifying bacteria, which are commonly found where ammonia is present (say from refinery or fertilizer plant leaks). They are principally aerobic and oxidize ammonia to nitrate, causing serious local falls in pH that result in nitric acid corrosion. Examples are Nitrosomonas sp. and Nitrobacter sp. [Pg.104]

Inorganic gases Oxides of nitrogen Oxides of sulfur Other inorganics Nitrogen dioxide, nitric oxide Sulfuric acid, sulfur dioxide Carbon monoxide, chlorine, ozone, hydrogen sulfide, hydrogen fluoride, ammonia One of the principal pollutants is sulfur dioxide, which is a corrosive acid gas that combines with water vapor in the atmosphere to produce acid rain. [Pg.11]

DOT CLASSIFICATION 2.3 Label Poison Gas, Oxidizer, Corrosive SAFETY PROFILE Poison by inhaladon. A corrosive material. Vigorous reacdon in contact with water or anhydrous nitric acid. Violent reacdon on contact with metals. When heated to decomposidon it emits very toxic fumes of CL and F . See also CHLORINE, FLUORINE, FLUORIDES, and CHLORINE TRIFLUORIDE. [Pg.316]

Nitric oxide, NO, is produced in internal combustion engines. When NO comes in contact with air, it is quickly converted into nitrogen dioxide, NO2, a very poisonous, corrosive gas. What mass of O is combined with 3.00 g of N in (a) NO and (b) NO2 Show that NO and NO2 obey the Law of Multiple Proportions. [Pg.85]

Its unpaired electron makes nitric oxide very reactive. Molecules that contain unpaired electrons are called radicals. NO reacts with O2 to form NO2, a brown, corrosive gas. [Pg.961]

When some metals or alloys are immersed in an oxidizing solution, corrosion does not occm, although it is favored thermodynamically. For example, iron will dissolve in dilute, but not in concentrated nitric acid. Corrosion is prevented because of the formation of a protective oxide film on the metal surface. This loss in chemical reactivity of a metal is known as passivation. Metals which readily undergo passivation in damp air include Fe, Al, Cr, Ni, Ti, and Pt. [Pg.1811]

ACID AMMONIUM FLUORIDE (1341-49-7) FiH H4N Reacts with water, forming a weak solution of hydrofluoric acid. Violent reaction with bases, releasing ammonia gas. Attacks glass, cement, and most metals in the presence of moisture. Upon contact with moisture and metal, this material may release flammable hydrogen gas which may collect in enclosed spaces. Do not use aluminum, nickel, or steel containers. When heated to decomposition, emits toxic and corrosive fumes of ammonia, hydrogen fluoride, and nitric oxides. [Pg.24]

SODIUM MONOXIDE (1313-59-3 12401-86-4) NujO Violent reaction with water, forming corrosive sodium hydroxide. Violent reaction with acids, nitrated materials such as 2,4-dinitrotoluene. Incompatible with nitric oxide, phosphoms(V) oxide. Aqueous solution is incompatible with alcohols, aldehydes, alkylene oxides, cresols, caprolactam solution, epichlorohydrin, organic anhydrides, glycols, phenols may undergo exothermic decomposition with maleic anhydride. In case of fire use approved Class D extinguishers (e.g., Met-L-X or Lith-X ) or smothering quantities of dry sand, crushed limestone, clay. [Pg.961]
