1、 Overview:

The molecular formula is HNO3

Physicochemical properties: pure nitric acid is a colorless fuming liquid, and the general commodity is slightly yellow. Nitric acid is irritant and unstable. It will decompose and release nitrogen dioxide when exposed to light or heat. Density 1.5027 (25 ℃), boiling point 83 ℃, freezing point - 42 ℃. It can be mixed with water in any proportion. Concentrated nitric acid is highly corrosive. It will burn if it touches the skin, and can also damage the mucous membrane and respiratory tract. It is a strong oxidant, which can cause combustion when mixed with organic matter and sawdust. Nitric acid is one of the three strong acids and has the generality of acids.

IIPurpose:

IIIProduct quality:

Because the concentrated nitric acid must be packed in ceramic cans or aluminum cans, it is very inconvenient, so it is diluted into a solution containing 68% HNO3 and packed in polyethylene plastic barrels.

Yellowish liquid in appearance

HNO3 content 67-69%

Sulfuric acid ≤ 0.08%

Residue ≤ 0.03%

Density ≥ 1.3

IVPackaging and storage:

25kg plastic barrel or stainless steel tank car for delivery. Store separately for no more than three months, otherwise volatilization will gradually reduce the content. Strictly prevent contact with various organic substances.

matters needing attention:

It can be stacked separately in the open air to avoid the sun. Avoid direct contact with eyes and skin to avoid burns. Operators should wear protective clothing, rubber gloves and glasses.
