FAQ — Ethylidene Chloride (1,1-Dichloroethane) (CAS 75-34-3)

What is Ethylidene Chloride (1,1-Dichloroethane)?

Ethylidene Chloride, also known as 1,1-Dichloroethane, is a chlorinated hydrocarbon (C₂H₄Cl₂) widely used as a solvent and as an intermediate in chemical synthesis. It is a clear, volatile liquid with a chloroform-like odor.

What are the main applications of Ethylidene Chloride?

It is mainly used as an intermediate in the production of vinylidene chloride (for polymers and resins), as a solvent in organic synthesis, and in small-scale applications such as degreasing or extraction processes.

Is Ethylidene Chloride hazardous?

Yes. It is classified as a flammable liquid and may cause irritation to the eyes, skin, and respiratory tract. Prolonged exposure can affect the central nervous system. Always handle according to the Safety Data Sheet (SDS) and local regulations.

How should Ethylidene Chloride be stored?

Store in a cool, dry, well-ventilated area away from heat and ignition sources. Keep containers tightly closed and segregated from strong oxidizers and incompatible materials. Use explosion-proof equipment where necessary.

What should I do in case of a spill or leak?

Evacuate non-essential personnel, remove ignition sources, and ventilate the area. Absorb small spills with inert, non-combustible material (e.g., vermiculite, dry sand). Collect into labeled hazardous-waste containers. Prevent release into drains and waterways. Refer to the SDS for detailed emergency procedures.

How is Ethylidene Chloride transported?

It is regulated as a hazardous material. Typically assigned UN 2362 (1,1-Dichloroethane), classified under Class 3 (Flammable liquids). Packaging group and other requirements depend on transport regulations (ADR, IMDG, IATA). Always verify with the current SDS and applicable transport codes.

Where can I find detailed safety and regulatory information?
