Useful:

• Chemical Classes: Solvents -> Chlorinated Aliphatics
• Canonical SMILES: CCl
• Inhalation Risk: A harmful concentration of this gas in the air will be reached very quickly on loss of containment.
• Effects of Short Term Exposure: The liquid may cause frostbite. The substance may cause effects on the central nervous system. Exposure far above the OEL could cause liver, cardiovascular system and kidney damage. Exposure could cause unconsciousness. Medical observation is indicated. The effects may be delayed.
• Effects of Long Term Exposure: The substance may have effects on the central nervous system. This may result in effects measured using behavioural tests. Animal tests show that this substance possibly causes toxic effects upon human reproduction.

Technology Process of Methyl chloride

There total 800 articles about Methyl chloride 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:
