neopentyl glycol%gas chromatography%internal standard curve%quantitative analysis
The method for quantitative analysis of neopentyl glycol (NPG) in Water-based muhicomponent system by gas chromatography internal standard curve using 1,3-propanediol as internal standard has been developed. The linear regression equation is y = 0.02786x-0.00627, regression coefficient is 0.9989, the relative standard deviation is 1.88%, the detection limit of this method is 2. 0 × 10~(-6)g/mL and the average recovery is from 99% to 101%. The method has been successfully applied to analyzing the contents of neopentyl glycol in aqueous solutions produced by different processes for preparation of neopentyl glycol.
