1,1,2-Trichloroethane may be harmful by inhalation, ingestion, and skin contact. It is a respiratory and eye irritant. 1,1,2-TCA is a central nervous system depressant and inhalation of vapors may cause dizziness, drowsiness, headache, nausea, shortness of breath, and unconsciousness. [5]
The earliest record of trichloroethylene synthesis dates back to 1836. It was obtained from the action of potassium hydroxide on 1,1,2,2-tetrachloroethane and 1,1,1,2-tetrachloroethane by Auguste Laurent and notated as C 4 HCl 3 (then the atomic weight of carbon was thought to be the half of it really was).
1,1,2-Trichloro-1,2,2-trifluoroethane, also called trichlorotrifluoroethane (often abbreviated as TCTFE) or CFC-113, is a chlorofluorocarbon. It has the formula Cl 2 FC−CClF 2 . This colorless, volatile liquid is a versatile solvent.
The major side-product is the related compound 1,1,2-trichloroethane, from which the 1,1,1-trichloroethane can be separated by distillation. A somewhat smaller amount of 1,1,1-trichloroethane is produced from the reaction of 1,1-dichloroethene and hydrogen chloride in the presence of an iron(III) chloride catalyst: CH 2 =CCl 2 + HCl → CH 3 CCl 3

In particular, 1,1,2-trichloroethane, 1,3-butadiene, acrolein, benzene, m-,p-,o-xylenes, naphthalene, trichloroethylene, and vinyl chloride were detected. An associate professor from CMU, Albert Presto, said that acrolein was a cause for continuing research because of potential risk.
