[4] 1,2-Dichloroethane is also used generally as an intermediate for other organic chemical compounds, and as a solvent. It forms azeotropes with many other solvents, including water (at a boiling point of 70.5 °C or 158.9 °F or 343.6 K) and other chlorocarbons. [5]
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 ...

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.
The preservation of foods has evolved greatly over the centuries and has been instrumental in increasing food security. The use of preservatives other than traditional oils, salts, paints, [ clarification needed ] etc. in food began in the late 19th century, but was not widespread until the 20th century.
Dichloroethane can refer to either of two isomeric organochlorides with the molecular formula C 2 H 4 Cl 2: 1,1-Dichloroethane (ethylidene chloride) 1,2-Dichloroethane (ethylene dichloride)
1,1-Dichloroethylene, commonly called vinylidene chloride or 1,1-DCE, is an organochloride with the molecular formula CCl 2 CH 2.It is a colorless liquid with a sharp odor. Like most chlorocarbons, it is poorly soluble in water but soluble in organic solvents. 1,1-DCE was the precursor to the original clingwrap, Saran, for food, but this application has been phased
It is also produced by direct chlorination or oxychlorination utilizing ethylene as feedstock and by catalytic chlorination of ethane or chlorination of 1,2- dichloroethane. [8] 1,1,2,2-Tetrachloroethane is always produced in closed systems to obtain the highest yield. Common side products that are created during the synthesis of 1,1,2,2 ...
