Hydrogen chloride (HCl) is a colorless gas with a strong odor pungent gas. Vapor pressure 4225.6kPa (20°C); Melting point -114.2°C; Boiling point -85.0°C; Solubility: easily soluble in water; Density: Relative density (water=1) 1.19; Relative density (air=1) 1.27; Stability: Stable; Hazard Mark 5 (Non-Combustible Gas); White smoke in the air is easily soluble in water and becomes hydrochloric acid, which can interact with a variety of metals and non-metals. Industries exposed to hydrogen chloride in industry include chemical, petroleum, metallurgy, printing and dyeing, etc. It is mainly used to make dyes, fragrances, medicines, various chlorides and corrosion inhibitors
The product is colorless and toxic. It is suffocating, highly irritating, highly hygroscopic and corrosive. No combustion, no combustion. After the leak, acid mist forms in the atmosphere, which smokes strongly. It is easily soluble in water and forms hydrochloric acid.
Pure liquid hydrogen chloride does not react with most metals, but occurs when water is present, forming metal chlorides and producing hydrogen. Organic compounds such as alcohols, aldehydes, ketones, acids, esters, ethers, paraffins, etc. are soluble in liquid hydrogen chloride and react.
