Adipic Anhydride CAS 2035-75-8

1. Adipic anhydride is a solid dispersant used as a chemical intermediate in the production of polycarboxylic acids and polyamide resins, which are degradable plastics derived from adipic acid .
2. Adipic anhydride CAS 2035-75-8 is utilized in the preparation of amides with carboxylic acid or amine derivatives, and its polymer, polyadipic anhydride, can be used to synthesize microspheres for drug delivery research .
3. Adipic anhydride CAS 2035-75-8 functions as a food additive, approved by the FDA for use as a flavoring agent or adjuvant, leavening agent, and pH control agent in food products .
4. In polymer research, Adipic anhydride is employed to modify polyisocyanurate foams, introducing amide linkages that improve thermal stability and reduce friability compared to unmodified foams .

1. Adipic anhydride must be stored in a tightly sealed container in a cool, dry, and well-ventilated environment; powder is stable for up to 3 years at -20°C or 2 years at 4°C .
2. For solution storage, prepare aliquots in tightly sealed vials and store at -20°C for up to 1 month or at -80°C for up to 6 months, avoiding repeated freeze-thaw cycles .
3. Adipic anhydride CAS 2035-75-8 is considered non-hazardous under GHS criteria, but personnel should wear chemical-resistant gloves, safety goggles with side-shields, and protective clothing when handling this substance .
4. Keep away from incompatible materials such as strong oxidizing agents, strong acids, and strong bases to prevent decomposition .

1. Isolate the spill area, ensure adequate ventilation, and wear full personal protective equipment including chemical-resistant gloves, safety goggles, and suitable dust respirator when Adipic anhydride is released .
2. Collect Adipic anhydride CAS 2035-75-8 by sweeping or vacuuming without creating dust using non-sparking tools, or mix with inert absorbent materials such as sand or diatomite, and place into suitable closed containers for disposal .
3. Avoid creating dust clouds during cleanup to prevent respiratory exposure; decontaminate surfaces and equipment by scrubbing with alcohol .
4. Prevent Adipic anhydride CAS 2035-75-8 from entering drains or water courses; dispose of collected material according to local, state, and federal environmental regulations .

1. Adipic anhydride is not classified as highly flammable but may decompose under fire conditions, emitting irritant fumes .
2. Use Adipic anhydride CAS 2035-75-8 water spray, dry chemical powder, carbon dioxide, or foam to extinguish fires involving the product .
3. Firefighters should wear self-contained breathing apparatus in pressure-demand, MSHA/NIOSH approved, and full protective gear when handling burning Adipic anhydride due to hazardous decomposition gases such as carbon monoxide .
4. During combustion, may emit irritant and toxic fumes; contain fire runoff to prevent environmental contamination .
