| 摘 要： | 采用气相色谱法测定碳酸甘油酯粗产品中碳酸甘油酯和残余甘油的含量。选择HP1701毛细管柱,程序升温及四甘醇内标物作为色谱条件,在此条件下碳酸甘油酯和残余甘油能很好地分离。碳酸甘油酯和甘油的线性范围分别为23.30～116.6 g.L-1和3.70～18.40 g.L-1。方法的回收率在99.1%～100.9%之间,相对标准偏差(n=6)在0.61%～1.93%之间。

| Abstract: | Glycerol carbonate and residual glycerin in the crude product of glycerol carbonate were determined by GC with HP 1701 capillary column.Gradient elevation of column temperature and using of tetraethylene glycol as internal standard were adopted in the analysis.Clear separation between glycerol carbonate and glycerin was attained under the optimized conditions.Linearity ranges of glycerol carbonate and glycerin were kept in the ranges of 23.30-116.6 g·L-1 and 3.70-18.40 g·L-1.Values of recovery and RSD′s(n=6) found were in the ranges of 99.1%-100.9% and 0.61%-1.93%,respectively. |
