Use: It is an excellent polar solvent for synthetic and natural resins, applicable to polymerization of polyimide, polysulfonamide and other high molecular compounds, to filming and spinning of synthetic resins, as well as to the synthesis of drugs, to crystallization and purification of aromatic dicarboxylic acids(e.g. terephthalic acid). The reactions of elimination, halogenation, cyclization, alkylation, transesterification are catalyzed and yields enhanced by the use of DMAC as a reaction medium.
Packing: Iron drum 180kg.
Storage: Should be stored in a cool and dark place and kept in an airtight condition.
