General description

N,N-Dimethylacetamide (DMAc) is a water-miscible organic solvent used in the synthesis of styrene, vinyl resin, linear polyester, acrylic fiber, plastic, pesticide, and synthetic leather. It participates in dehydrogenation, dehydration, halogenation, deprotonation reactions and reductive carbonylation of transition metals. It can also act as catalysts, promoters, halogen/alkoxy or hydroxyl/halogen exchange mediators, reducing agents, and sources of the base.
