  Dimethylacetamide is used as a solvent in polymer processing and moisture in
DMA affects the morphology and mechanical properties of the polymer products.
This paper describes a method for determination of trace moisture content in
DMA by acetylene production - gas chromatography. In the condition of 30
centigrade and ultrasonic dispersion, moisture in DMA sample was reacted with
calcium carbide and its product of acetylene was measured by gas
chromatography. By this way, trace moisture in DMA was determined with RSD of
2.272 percent and limit of measurement was 0.002 percent.
