Useful:

• Chemical Classes: Toxic Gases & Vapors -> Oxidizers
• Canonical SMILES: ClCl
• Recent ClinicalTrials: A Clinical Trial of Breast Cancer Neo-adjuvant Therapy Based on Molecular Pathway in FUSCC
• Inhalation Risk: On loss of containment, a harmful concentration of this gas in the air will be reached very quickly.
• Effects of Short Term Exposure: Lachrymation. The substance is corrosive to the eyes, skin and respiratory tract. Rapid evaporation of the liquid may cause frostbite. Inhalation may cause asthma-like reactions. Inhalation may cause pneumonitis. Inhalation may cause lung oedema, but only after initial corrosive effects on eyes and/or airways have become manifest. Exposure could cause death.
• Effects of Long Term Exposure: The substance may have effects on the respiratory tract and lungs. This may result in chronic inflammation and impaired functions. The substance may have effects on the teeth. This may result in erosion.

Technology Process of Chlorine

There total 1084 articles about Chlorine which guide to synthetic route it. The literature collected by LookChem mainly comes from the sharing of users and the free literature resources found by Internet computing technology. We keep the original model of the professional version of literature to make it easier and faster for users to retrieve and use. At the same time, we analyze and calculate the most feasible synthesis route with the highest yield for your reference as below:

synthetic route:
