HH-MTBEIV毛细管柱 工业甲基叔丁基醚MTBE甲醇测定

关于MTBE中甲醇的测定，通常采用聚聚硅氧烷固定相，即使150m的柱长，也不能完全放开甲醇和轻烃，无法准确定量。此外也有采用二维/多维色谱法或者中心切割法，操作复杂，设备成本高，一般企业很难配置，根本无法普及。

滕州市浩瀚色谱仪器技术服务有限公司，，，，，色谱工程研究所，分析与测试中心，3个科研单位，研发出《工业甲基叔丁基醚MTBE甲醇测定毛细管柱》，在一定的分析条件下，使ＭＴＢＥ及其杂质甲醇得到很好的分离。测定了各组分在ＦＩＤ检测器上的相对重量校正因子。主要组分的相对误差小于３．５％。用该分析方法得到的分析结果在某种程度上可以用来判断装置的运行情况，指导工业生产。

Industrial methyl tert-butyl ether MTBE methanol determination capillary column

Methyl tert-butyl ether (MTBE) is the reaction product of isobutylene and methanol, and is one of the effective blending components of high-octane gasoline.
Regarding the determination of methanol in MTBE, polysiloxane stationary phases are usually used. Even with a column length of 150 m, methanol and light hydrocarbons cannot be completely released and cannot be accurately quantified. In addition, there are also two-dimensional/multidimensional chromatography or heart-cutting methods, which are complicated to operate and high equipment costs. It is difficult for general enterprises to configure and cannot be popularized at all.

Tengzhou Haohan Chromatography Instrument Technology Service Co., Ltd. is advancing with the times, guided by the concept of scientific development, under the leadership of Manager Wang Xiaoying, relying on Xiangying Institute of Analytical Technology, Chromatography Engineering Institute, Analysis and Testing Center, 3 scientific research The unit developed the "Industrial methyl tert-butyl ether MTBE methanol determination capillary column", under certain analytical conditions, so that MTBE and its impurity methanol can be well separated. The relative weight correction factor of each component on the FID detector was determined. The relative error of the main components is less than 3.5%. The analysis results obtained by this analysis method can be used to judge the operation of the device to a certain extent and guide industrial production.
