Chlorine - Nature

liquid chlorine is a yellow-green transparent liquid. d20 (6. 864atm)1.4085 (liquid);d-35(0. 9949atm)1.5649 (liquid); Boiling point -34.6 °c; Melting point -100. 98 °c. 300L gas chlorine at atmospheric pressure can be obtained after gasification of lkg liquid chlorine, the critical temperature of the gas is 1 44 ℃, the critical pressure is 76.1 atm, and the critical relative density is 0. 573. Highly irritating and corrosive. Very lively nature, can be soluble in water, solubility decreases with the increase of water temperature; Although not spontaneous combustion, but can combustion, in the sunlight and other flammable gas mixture will burn and explosion, it can react with most elements or compounds. With strong oxidation.

Chlorine - Preparation Method

In general, electrolytic aqueous salt solution is used to prepare chlorine gas, and then the chlorine gas is cooled to prepare liquid chlorine.

Chlorine - Use

chlorine is a strong oxidant, which can oxidize some organic corrosion and scale inhibitors in cooling water in different degrees. Chlorine can also react with organic solvents in water to generate chlorinated hydrocarbons, which have been proved to be carcinogenic, and the free residual chlorine in the discharged wastewater is toxic to aquatic organisms. It is best to use with non-oxidizing bactericide and slime stripping agent.

Chlorine - Safety

has a strong irritating odor and corrosive, highly toxic, especially to the respiratory organs have a stimulating effect. Irritation of the mucosa, resulting in eye tears, so that the eyes, nose, pharynx have burning, tingling and suffocation. Inhalation can cause Nausea, Vomit, upper abdominal pain, Diarrhea, etc. Excessive inhalation can cause respiratory disorders until death. Combustion-supporting. The maximum allowable concentration in the air of the production environment is 2 mg/ma. The cylinder containing chlorine shall be strictly sealed to prevent air leakage. Liquid chlorine storage should be low temperature refrigeration, ground ventilation.
