1,1,2,2-tetrachloroethane was used in large amounts to produce other chemicals like trichloroethylene, tetrachloroethylene, and 1,2-dichloroethylene. [6] Because of its possible carcinogen effects on humans, the production of 1,1,2,2-tetrachloroethane has decreased significantly and is no longer widely used as an end-product. [7]
1,1,1,2-Tetrachloroethane can be obtained by a two-step addition reaction of acetylene with chlorine (via dichloroethene), but this mainly produces 1,1,2,2-tetrachloroethane. C 2 H 2 + Cl 2 → C 2 H 2 Cl 2 C 2 H 2 Cl 2 + Cl 2 → C 2 H 2 Cl 4. It can be obtained directly by chlorination of 1,1,2-trichloroethane: [3] CHCl 2 −CH 2 Cl + Cl 2 ...

In mathematics, the infinite series 1 / 2 + 1 / 4 + 1 / 8 + 1 / 16 + ··· is an elementary example of a geometric series that converges absolutely. The sum of the series is 1. In summation notation, this may be expressed as
1,1,1,2-Tetrachloropropane is a compound of chlorine, hydrogen, and carbon. It has chemical formula C 3 H 4 Cl 4. The structure has a propane skeleton, but four of the hydrogen atoms are replaced by chlorine atoms.
1,1,1,2,2,3,3-Heptachloropropane is a compound of chlorine, hydrogen, and carbon. Its linear formula is C 2 Cl 5 CHCl 2. Heptachloropropane is made in a modified Friedel-Crafts or Prins reaction from chloroform and tetrachloroethylene with catalytic aluminum chloride. Dehydrochlorination with a base gives hexachloropropene.
The Model 1 + 1 ⁄ 2 had three issues. The first two (known as the first and second issues) were "tip-up" revolvers with the barrel release catch located on the side of the frame in front of the trigger, while the third (known as the "Model 1 + 1 ⁄ 2 Single Action Revolver") was a "top-break", with the barrel release catch located on the top of the frame, just in front of the hammer.
