Determination of Methanol and Propylene Oxide Residues in Polypropylene Carbonate by Capillary Column
Determination of Methanol and Propylene Oxide Residues in Polypropylene Carbonate by Capillary Column Details:


Name: capillary column
Stationary phase: 6% nitrile propylphenyl 94% dimethylpolysiloxane,
Specifications: 30m*0.53mm*0.3um
Model: HH-624
Application: Determination of methanol and propylene oxide residues in polypropylene carbonate by gas chromatography

Haohan Chromatography (Shandong) Application Technology Development Co., Ltd. used headspace capillary gas chromatography to determine the residual amounts of methanol and propylene oxide in polypropylene carbonate (PPC). The results showed that the linear ranges of methanol and propylene oxide were respectively were 0.25~4.00 g.L-1 (r=0.999 4), 0.25~4.00 g.L-1 (r=0.999 7); the average recoveries of methanol and propylene oxide were 95.4% and 98.3%, respectively; RSD (n=5) 3.7% and 1.8%, respectively. The method is simple, accurate, highly sensitive and reproducible, and is suitable for the determination of methanol and propylene oxide residues in polypropylene carbonate (PPC).
