[Analysis for monobromo- and dibromo-pentaerythritol by gas chromatography]

A method for separation and determination of dibromo-pentaerythritol (DBPT), monobromo-pentaerythritol (MBPT), and tribromo-pentaerythritol (TBPT) by gas chromatography was developed. The conditions for determination were: BPX-70 capillary column, operated at 240 degrees C, with both FID detector and injector at 280 degrees C. Xylitol was the internal standard. Linear regression equations were YDBPT = 0.0423X-0.0124 (r = 0.9998) and YMBPT = 0.0634X-0.0835(r = 0.9966). This method is rapid, simple and accurate.
