WebTrichloroethylene overview. Trichloroethylene (TCE; C2 HCl 3) is a chlorinated halocarbon primarily used for its powerful action on greases, oils, resins, waxes, and other natural and synthetic substances. Currently, 80%–90% of TCE manufactured worldwide is used for the industrial degreasing of metals ( Bakke, Stewart, & Waters, 2007 ). canada trust branches london onWebDichloroacetylene is neurotoxic, nephrotoxic, and nephrocarcinogenic.
