Description

High security sampling test device of nitrogen trichloride

Technical Field

The utility model relates to a sampling test technical field specifically is a high security sampling test device of nitrogen trichloride.

Background

The nitrogen trichloride (NCl 3) molecule is in a triangular cone shape, because 3 chlorine atoms in the molecule are gathered on the same side, larger repulsive force and obstruction exist among the chlorine atoms, meanwhile, the electronegativity of nitrogen and chlorine elements is close (nitrogen is slightly larger than chlorine), and under the excitation of smaller external capacity, nitrogen-chlorine bonds (N-Cl) can be broken to cause the decomposition of the nitrogen trichloride. The spontaneous combustion explosion point is 95 ℃. Nitrogen trichloride is a dangerous and unstable substance which gradually decomposes at temperatures below 60 ℃ to produce nitrogen and chlorine, which under certain conditions reaches a reversible equilibrium with the formation reaction.

Pure nitrogen trichloride reacts strongly with organic substances such as ozone, phosphide, nitrogen oxide, rubber, oils and the like. The liquid will explode when heated to 60-95 deg.C, the explosion temperature in air is about 1700 deg.C, the highest explosion temperature in sealed container is 2128 deg.C, and the maximum explosion pressure is 543.2 MPa. The potential explosion hazard exists when the volume fraction of gas in the gas phase is 5.0% to 6.0%. The explosive can be decomposed and exploded under the condition of vibration or ultrasonic wave at 60 ℃ in a closed container, and can be spontaneously exploded at 93-95 ℃ in a non-closed container. Under the influence of sunlight, magnesium light irradiation or collision energy, the explosion is easier, and experiments show that electric spark can be detonated when the volume fraction of the nitrogen trichloride is more than 1%.

When current sample detection device was to nitrogen trichloride, because nitrogen trichloride is a dangerous and unstable material, most sample detection device now can not effectively prevent revealing of nitrogen trichloride gas, inconvenient transportation, therefore we make the improvement to this, provide a high security sample detection device of nitrogen trichloride.
