Ethylene dichloride, abbreviated as EDC, is a chemical compound with the molecular formula C2H4C2. It is a colorless liquid with a pungent odor and is flammable. EDC is known as one of the most important raw materials in the petrochemical industry and is mainly used in the production of vinyl chloride monomer (VCM), which is the main chemical for the production of polyvinyl chloride (PVC). Ethylene dichloride is produced by chlorinating ethylene in the presence of a catalyst. This process is carried out on a large industrial scale, and millions of tons of this chemical are produced worldwide annually.

Environmental impact of EDC

Ethylene Dichloride (EDC) has significant negative impacts on the environment. In the event of a leak, it can leach into groundwater resources and degrade water quality due to its chemical stability and low water solubility. EDC slowly decomposes in the atmosphere, leading to the release of chlorinated gases that may contribute to ozone depletion. Therefore, careful control of its use and disposal is essential to prevent environmental pollution.

Safety Measures and Regulations for Handling EDC

EDC is a toxic substance and can be harmful if inhaled, swallowed or comes into contact with skin. It may cause irritation to the skin, eyes and respiratory system.

It is highly flammable and should be kept away from sources of sparks or flame.

It should be Stored in a dry, cool, well-ventilated area. Keep away from direct sunlight, heat, and sources of ignition. Store in sturdy, corrosion-resistant containers (such as stainless steel or special tanks), with a sealed lid.
