  2. 1,2-Dichloroethane - Wikipedia

    en.wikipedia.org/wiki/1,2-Dichloroethane

    The chemical compound 1,2-dichloroethane, commonly known as ethylene dichloride (EDC), is a chlorinated hydrocarbon. It is a colourless liquid with a chloroform -like odour . The most common use of 1,2-dichloroethane is in the production of vinyl chloride , which is used to make polyvinyl chloride (PVC) pipes, furniture and automobile ...

    en.wikipedia.org/wiki/HAZMAT_Class_2_Gases

    A gas is a substance which (a) at 50 °C (122 °F) has a vapor pressure greater than 300 kPa (43.51 PSI) or (b) is completely gaseous at 20 °C (68 °F) at a standard pressure of 101.3 kPa (14.69 PSI). Gases are assigned to one of three divisions division 2.1 Flammable gas; division 2.2 Non flammable, Non-toxic gas; division 2.3 Toxic gas

  7. 1,1-Dichloroethylene - Wikipedia

    en.wikipedia.org/wiki/1,1-Dichloroethylene

    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. [3] Cl 2 CHCH 2 Cl + NaOH → Cl 2 C=CH 2 + NaCl + H 2 O

  8. 1,2-Dichloroethylene - Wikipedia

    en.wikipedia.org/wiki/1,2-dichloroethylene

    1,2-Dichloroethylene or 1,2-DCE is the name for a pair of organochlorine compounds with the molecular formula C 2 H 2 Cl 2. The two compounds are isomers, each being colorless liquids with a sweet odor. It can exist as either of two geometric isomers, cis-1,2-dichloroethene or trans-1,2-dichloroethene, but is often used as a mixture of the two ...

  9. Tetrachloroethylene - Wikipedia

    en.wikipedia.org/wiki/Tetrachloroethylene

    Several other methods have been developed. When 1,2-dichloroethane is heated to 400 °C with chlorine, tetrachloroethylene is produced: ClCH 2 CH 2 Cl + 3 Cl 2 → Cl 2 C=CCl 2 + 4 HCl. This reaction can be catalyzed by a mixture of potassium chloride and aluminium chloride or by activated carbon.
