543-67-9 Usage
Uses
Jet propellant.
General Description
A colorless liquid with a sweet, ethereal odor. Highly toxic by inhalation and ingestion. Flash point 61°F. A dangerous fire risk. Used as a solvent and as a dielectric fluid.
Air & Water Reactions
Highly flammable.
Reactivity Profile
N-PROPYL NITRITE is an oxidizing agent. If mixed with reducing agents, including hydrides, sulfides and nitrides, may begin a vigorous reaction that culminates in a detonation. Reacts with inorganic bases to form explosive salts.
Health Hazard
TOXIC; inhalation, ingestion or contact (skin, eyes) with vapors, dusts or substance may cause severe injury, burns or death. Reaction with water or moist air will release toxic, corrosive or flammable gases. Reaction with water may generate much heat that will increase the concentration of fumes in the air. Fire will produce irritating, corrosive and/or toxic gases. Runoff from fire control or dilution water may be corrosive and/or toxic and cause pollution.
Fire Hazard
Non-combustible, substance itself does not burn but may decompose upon heating to produce corrosive and/or toxic fumes. Vapors may accumulate in confined areas (basement, tanks, hopper/tank cars etc.). Substance will react with water (some violently), releasing corrosive and/or toxic gases and runoff. Contact with metals may evolve flammable hydrogen gas. Containers may explode when heated or if contaminated with water.
Check Digit Verification of cas no
The CAS Registry Mumber 543-67-9 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 5,4 and 3 respectively; the second part has 2 digits, 6 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 543-67:
(5*5)+(4*4)+(3*3)+(2*6)+(1*7)=69
69 % 10 = 9
So 543-67-9 is a valid CAS Registry Number.

Process for Producing C1-C4 Alkyl Nitrite

Page/Page column 4, (2011/10/31)
A process of producing C1-C4 alkyl nitrite, comprising the following steps: a) firstly feeding nitrogen oxide and oxygen into Reactor I, contacting with an aluminosilicate catalyst, and reacting to produce an effluent I containing NO2 and unreacted NO; b) feeding the effluent I and C1-C4 alkanol into Reactor II, and reacting to produce an effluent II containing C1-C4 alkyl nitrite; and c) separating the effluent II containing C1-C4 alkyl nitrite to obtain C1-C4 alkyl nitrite; wherein reactor I is a fixed bed reactor, and Reactor II is a rotating high-gravity reactor; said nitrogen oxide in step a) is NO, or a mixed gas containing NO and one or more of N2O3 and NO2, wherein the molar number of NO is greater than that of NO2, if any; and the molar ratio of NO in nitrogen oxide to oxygen is 4-25:1.

Organic nitrites can be produced from a compound which is a mono/polyhydric alcohol or an aldehyde- or ketone-derivate thereof after de-aeration of the same, using NO gas, and stored in an environment saturated with gaseous NO. Organic nitrites produced according to the invention exhibit less impurities and improved storage stability compared to conventionally produced nitrites. The organic nitrites of the invention can easily be formulated into pharmaceutical compositions and have utility for the treatment of various conditions.
