2-hydroxyethyl pyridine is a widely used of fine chemical products, is an important intermediate for the synthesis of 2 vinyl pyridine and many other fine organic chemical products, in polymer materials, surface active agent, medicine, pesticide and so on has a wide range of uses, has a higher open value 0.2 hydroxyethyl pyridine synthesis by 2 methyl pyridine and formaldehyde reaction. As the reaction under atmospheric pressure is a reversible reaction.
Tengzhou City Xiangying Analysis Technology Co., Ltd. the XiangyingGC7990plus temperature gas chromatography method for the determination of 2-hydroxyethyl pyridine synthesis liquid formaldehyde, water, 2 methyl pyridine and 2-hydroxyethyl pyridine content method. Qualitative method for relative retention value method, quantitative method corrected area normalization method. The accuracy and precision of the method were also discussed. Results show that, the method is accurate, simple and fast, for the analysis of 2-hydroxyethyl pyridine synthesis research, synthetic liquid separation and industrial production process control, with satisfactory results. The relative standard deviation of the method is less than 3%.
2 羟乙基吡啶是一种应用广泛的精细化工产品,是合成2 乙烯基吡啶和许多其它精细有机化工产品的重要中间体,在高分子材料,表面活性剂,医药、农药等方面有着广泛的用途,具有较高的开发价值.2 羟乙基吡啶的合成采用2 甲基吡啶和甲醛反应.由于该反应在常压下是一种可逆反应,
滕州市翔鹰分析技术有限公司采用XiangyingGC7990plus程序升温气相色谱法测定2 羟乙基吡啶合成液中甲醛、水、2 甲基吡啶和2 羟乙基吡啶含量的方法.定性方法为相对保留值法,定量方法为修正面积归一化法.对该方法的准确度和精密度也进行了讨论.结果表明,该方法准确、简便快速,用于2 羟乙基吡啶的合成研究、合成液的分离及工业化生产过程的控制分析,结果令人满意.方法相对标准偏差小于3%.
