气相色谱法分析工业甲醇中痕量三甲胺 详细信息：

名称：毛细管柱
固定液：碱性去活的聚乙二醇
规格：30m*0.25mm*0.25um
型号：HH-WAX
应用：工业用甲醇中痕量三甲胺含量的测定 气相色谱质谱联用法

以煤为原料生产甲醇时，由于在高温高压下进行，会发生一定的副反应，生成三甲胺(TMA)等副产物。虽经过精馏，但在精甲醇中仍存在一定量(1O*10-9-150*1O-9)的TMA。TMA是造成甲醇制丙烯(MTP)催化剂使用寿命短和失活的毒物，因此应严格控制甲醇中的TMA含量，这对MTP催化剂极其重要。


浩瀚色谱（山东）应用技术开发有限公司采用毛细管柱,用氮磷检测器(NPD)和内标法建立了工业甲醇中痕量三甲胺(TMA)的测定方法,该方法相关线性系数达到99.9%.高惰性衬管可解决吸附问题,可以快速,准确地测量工业甲醇中的TMA含量,为下游产品的生产提供操作数据.

Analysis of Trace Trimethylamine in Industrial Methanol by Gas Chromatography
Analysis of Trace Trimethylamine in Industrial Methanol by Gas Chromatography Details:

Name: capillary column
Fixative: Alkaline-deactivated polyethylene glycol
Specifications: 30m*0.25mm*0.25um
Model: HH-WAX
Application: Determination of trace trimethylamine content in industrial methanol by gas chromatography-mass spectrometry

When using coal as raw material to produce methanol, due to the high temperature and high pressure, certain side reactions will occur, resulting in trimethylamine (TMA) and other by-products. Although it has been rectified, there is still a certain amount of TMA (1O*10-9-150*1O-9) in the refined methanol. TMA is a poison that causes short service life and deactivation of methanol-to-propylene (MTP) catalysts, so the TMA content in methanol should be strictly controlled, which is extremely important for MTP catalysts.


Haohan Chromatography (Shandong) Application Technology Development Co., Ltd. used capillary column, nitrogen phosphorus detector (NPD) and internal standard method to establish a method for the determination of trace trimethylamine (TMA) in industrial methanol, the correlation linear coefficient of the method reached 99.9% .Highly inert liner can solve the adsorption problem, can quickly and accurately measure the TMA content in industrial methanol, and provide operational data for the production of downstream products.
