General description

1,1,2-Trichloroethane (1,1,2-TCA), a chlorinated aliphatic hydrocarbon, is a common groundwater pollutant. Microbial detoxification of 1,1,2-TCA has been studied. Ni supported on mesoporous silica (SBA-16) catalyzed hydrodechlorination of 1,1,2-trichloroethane has been reported. Rotational isomers of 1,1,2-trichloroethane in the gaseous and liquid states have been investigated by the infrared absorption spectra.

Application

  • Advanced Material Development: Research into the synthesis of UiO-66 3D photonic crystals highlights the use of 1,1,2-Trichloroethane in the creation of new materials for efficient vapor detection, supporting advancements in sensor technology (Wang et al., 2022).

1,1,2-trichloroethane (1,1,2-TCA) has become a common groundwater pollutant due to historically extensive utilization, improper disposal, as well as from incomplete dechlorination of 1,1,2,2-tetrachloroethane. Currently, limited information is available on microbial detoxification of 1,1,2-TCA. Desulfitobacterium sp. strain PR, which was isolated
