WebAug 16, 2024 · 1,1,1-Trichloroethane is a chlorinated hydrocarbon that was used widely before the implementation of the Montreal Protocol on Substances that Deplete the Ozone Layer, but that since the 1990s has been used mostly as a chemical feedstock in closed systems and for essential purposes, e.g. medical devices and aviation safety.
1,1-DCE is produced by dehydrochlorination of 1,1,2-trichloroethane, a relatively unwanted byproduct in the production of 1,1,1-trichloroethane and 1,2-dichloroethane. The conversion is a base-catalyzed reaction which uses either NaOH or Ca(OH)2 with temperature ca. 100 °C.
