What is Ethylene CAS 74-85-1?
Ethylene (CAS 74-85-1) is a colorless, highly flammable olefin gas and a cornerstone of modern chemical manufacturing. Due to its simple molecular structure and high reactivity, it is widely used as a primary raw material for polymers and chemical intermediates. Ethylene plays a central role in the production of plastics, solvents, antifreeze materials, and numerous industrial chemicals. When handled and stored under proper conditions, it offers excellent stability and unmatched industrial value.
Ethylene CAS 74-85-1 Use
Petrochemical Feedstock
Ethylene is one of the most important building blocks in the global petrochemical industry and serves as a starting material for numerous chemical processes.
Polyethylene (PE) production
Ethylene oxide and ethylene glycol
Styrene, PVC, and other downstream chemicals
Plastics & Materials Industry
Used extensively in the manufacture of plastic films, packaging materials, pipes, and molded products.
Agricultural Use
Ethylene functions as a natural plant hormone and is used in controlled environments to regulate fruit ripening and post-harvest handling (industrial and agricultural grades must be strictly separated).
Industrial Gas Applications
Applied in certain specialized industrial processes where reactive hydrocarbon gases are required.
Ethylene CAS 74-85-1 safety
Ethylene is classified as a highly flammable gas. When mixed with air, it can form explosive mixtures within certain concentration ranges.
Key safety considerations:
Ensure good ventilation during handling and use
Eliminate open flames, sparks, and static discharge
High concentrations may displace oxygen and cause suffocation
Follow standard industrial gas handling procedures
Ethylene is not considered highly toxic; its primary hazards are related to flammability, explosion risk, and oxygen displacement.
