HH-5 N-甲基吗啉测定毛细管柱的详细资料

N-甲基吗啉测定毛细管柱
N-甲基吗啉测定毛细管柱 详细信息:

名称:毛细管柱
固定相:5%苯基-甲基聚硅氧烷
规格:30m*0.32mm*0.5um
型号:HH-5
应用:N-甲基吗啉的气相色谱分析

由于N-甲酰吗啉特殊的分子结构和物理性能,其新的应用领域不断被开发。除了萃取精馏回收和精制芳烃,新近发现吗啉衍生物有较好的气体脱硫功效,净化气质量高,过程的操作费用低、投资省。

为了监测吗啉甲基化法生成N-甲基吗啉反应的收率,浩瀚色谱(山东)应用技术开发有限公司应用气相色谱建立了一套用N-甲基吡咯烷酮作为内标物,程序升温测定N-甲基吗啉质量分数的方法。该方法主要依托于GC-气相色谱,其检测器为氢火焰离子检测器,载气为氮气,色谱柱为HH-5毛细管柱(规格30 m×0.32 mm×0.5UMμm)。通过回收率和重复性的测定,验证了该方法准确度和精密度均较高,能够准确测定混合液中N-甲基吗啉的含量。

Capillary column for N-methylmorpholine determination
N-Methylmorpholine Determination Capillary Column Details:

Name: capillary column
Stationary phase: 5% phenyl-methyl polysiloxane
Specifications: 30m*0.32mm*0.5um
Model: HH-5
Application: Gas Chromatographic Analysis of N-Methylmorpholine

Due to the special molecular structure and physical properties of N-formylmorpholine, its new application fields are constantly being developed. In addition to extractive distillation to recover and refine aromatic hydrocarbons, morpholine derivatives have recently been found to have good gas desulfurization efficiency, high quality of purified gas, low operating costs and low investment in the process.

In order to monitor the yield of the reaction of morpholine methylation to N-methylmorpholine, Haohan Chromatography (Shandong) Application Technology Development Co., Ltd. applied gas chromatography to establish a set of temperature-programmed determinations using N-methylpyrrolidone as an internal standard. Method for mass fraction of N-methylmorpholine. The method mainly relies on GC- gas chromatography, the detector is hydrogen flame ion detector, the carrier gas is nitrogen, and the chromatographic column is HH-5 capillary column (30 m×0.32 mm×0.5UMμm). Through the determination of recovery rate and repeatability, it is verified that the method has high accuracy and precision, and can accurately determine the content of N-methylmorpholine in the mixture.
