Features Of Eastman DMAc Dimethylacetamide

  1. High-purity, low-water-content grade optimized for demanding polymer and pharmaceutical synthesis.

  2. Excellent thermal and chemical stability across a broad temperature range (−20 °C to 150 °C).

  3. Superior solvating power for polyimides, aramids, polyacrylonitrile (PAN), and cellulose derivatives.

  4. Low volatility and high boiling point (165–166 °C) enabling efficient solvent recovery in continuous processes.

  5. Consistent batch-to-batch quality supported by Eastman’s ISO 9001-certified manufacturing and rigorous QC protocols.

Typical Applications Of Eastman DMAc Dimethylacetamide

  1. Solvent for high-performance polymer spinning—especially polyacrylonitrile (PAN) and polyimide precursor solutions.

  2. Reaction medium in pharmaceutical active pharmaceutical ingredient (API) synthesis and peptide coupling reactions.

  3. Component in lithium-ion battery electrode slurry formulations for cathode materials (e.g., NMC, LFP).

  4. Solvent for membrane fabrication via phase inversion (e.g., hollow-fiber ultrafiltration and reverse osmosis membranes).

  5. Processing aid in carbon fiber precursor production and specialty coating systems.
