摘 要:建立了以2,5-二甲氧基四氫呋喃為原料水解合成的丁二醛樣品的氣相色譜測定法。選用HP-FFAP毛細管柱,柱溫80℃,流速 20 mL/min,以二氧六環(huán)為內標物,采用內標標準曲線(xiàn)法定量分析丁二醛含量。結果表明,方法在8.0~40.0 g/L的濃度范圍內呈良好線(xiàn)性關(guān)系(r=0.999 94),相對標準偏差RSD為0.52%,加標回收率在96.23%~102.87%之間。該法簡(jiǎn)便、快速,具有良好的精密度和準確度,可用于合成樣品中丁二醛含量的測定。

Abstract:A GC method was established for monitoring the succinaldehyde in the samples taking from the preparation reaction using 2,5-dimethoxy-dihydrofuran as the starting material. The content of succinaldehyde was quantitatively analyzed using internal standard curve method with a HP-FFAP capillary column and dioxane as internal standard substance. In this method, the flow rate was 20 mL/min and the column temperature was 80℃. The results indicated that this method had a good linear relation(r=0.999 94) in a concentration range from 8.0 g/L to 40.0 g/L with an average RSD of 0.52% and a recovery rate range from 96.2% to 102.8%. This method has been proved to be simple, rapid with good accuracy and reliability, which could be applicable in the monitoring of succinaldehyde in the samples taking from the preparation reaction using 2,5-dimethoxy-dihydrofuran as the starting material.
Key words:gas chromatography; succinaldehyde; 2,5-dimethoxy-dihydrofuran
