Tetrachloroethylene is degraded by hydrolysis, and is persistent under aerobic conditions. Chem. C2Cl4 is tetrachloroethylne using the systematic naming system, but its common name is perchlorethylene. This interval corresponds to midnight to until 5:00 am UTC on Tuesday December 29. Tetrachloroethylene is a chlorinated derivative of ethylene, H 2 C = CH 2, in which each of the four hydrogen atoms is replaced by chlorine, Cl 2 C = CCl 2.It is a heavy liquid that has been used to treat hookworm infection.
