Ethylenesulfate CAS 1072-53-3

1. Ethylenesulfate (DTD) CAS 1072-53-3 is primarily used as a film-forming additive in lithium-ion battery electrolytes to improve low-temperature performance, suppress battery swelling at high temperatures, and enhance charge-discharge cycle stability .
2. Ethylenesulfate serves as a key intermediate in the synthesis of specialty polymers and copolymers, contributing to materials with improved mechanical properties and chemical resistance .
3. Ethylenesulfate acts as a versatile alkylating agent and building block in organic synthesis, functioning as a hydroxymethylating reagent for preparing pharmaceutical intermediates and specialty chemicals .
4. Ethylenesulfate is utilized in the formulation of surfactants and agrochemicals, providing effective solutions for pest control, crop protection, and industrial cleaning applications .

1. Ethylenesulfate must be stored in a tightly sealed container in a cool, dry, and well-ventilated environment at 2-8°C, protected from light and moisture .
2. Ethylenesulfate is moisture-sensitive and should be stored under inert gas (nitrogen or argon), away from incompatible materials such as strong oxidizing agents .
3. Personnel must wear chemical-resistant gloves, safety goggles with side-shields, and protective clothing when handling Ethylenesulfate, as it causes skin and eye irritation and is harmful if swallowed .
4. Avoid formation of dust and aerosols; use local exhaust ventilation when dust or aerosol generation is possible, and wash thoroughly after handling.

1. Isolate the spill area immediately, ensure adequate ventilation, and wear full personal protective equipment including chemical-resistant gloves, safety goggles, and suitable dust respirator .
2. Collect Ethylenesulfate by sweeping or vacuuming without creating dust using non-sparking tools, and place into suitable closed containers for disposal .
3. Avoid creating dust clouds during cleanup to prevent respiratory exposure; prevent Ethylenesulfate from entering drains, water courses, or the environment .
4. Dispose of collected Ethylenesulfate material as hazardous waste according to local, state, and federal environmental regulations through licensed chemical destruction or controlled incineration .

1. Ethylenesulfate is not classified as highly flammable but is a combustible solid (Storage Class 11) that may decompose under fire conditions, emitting toxic fumes .
2. Use water spray, dry chemical powder, carbon dioxide, or alcohol-resistant foam to extinguish fires involving the product; do NOT use a direct water jet as Ethylenesulfate may scatter burning material .
3. Firefighters should wear self-contained breathing apparatus in pressure-demand, MSHA/NIOSH approved, and full protective gear when handling burning Ethylenesulfate due to hazardous decomposition gases generated by thermal decomposition .
4. Hazardous decomposition products formed under fire conditions include carbon monoxide, carbon dioxide, and sulfur oxides; contain fire runoff to prevent environmental contamination .
