What is hydrogen cyanide gas?
Hydrogen cyanide is an inorganic compound, HCN, in its standard state, liquid. Hydrogen cyanide is easy to be evenly dispersed in the air, and can be burned in the air. When the content of hydrogen cyanide in the air reaches 5.6%~12.8%, it is explosive. Hydrocyanic acid is highly toxic. The clinical manifestations of acute hydrogen cyanide poisoning are obvious bitter almond taste in the exhaled breath of patients, and the mild poisoning mainly shows chest tightness, palpitation, rapid heart rate, headache, nausea, vomiting and blurred vision.
The use of hydrogen cyanide
Appearance and Properties: Colorless gas or liquid, bitter almond taste.
Main Applications: Used in the manufacture of acrylonitrile and acrylic resins and pesticides.
Dangerous characteristics: this product is flammable, its vapor and air can form an explosive mixture, in case of open fire, high heat energy caused by combustion explosion; Long-term placement due to moisture and polymerization, the polymer itself has autocatalytic effect, can cause explosion.
What is a hydrogen cyanide gas detector?
Hydrogen cyanide gas detector, using high precision, long life of imported electrochemical hydrogen cyanide sensor, accurate detection work, widely used in various chemical plants.
