Abstract

A technique is proposed for determining the mass fractions of products of the catalytic ethylbenzene pyrolysis reaction on a capillary column with functionalized poly(1-trimethylsilyl-1-propyne) (PTMSP/N₂O). The capillary column with PTMSP/N₂O selectively separates methane, ethane, ethylene, and acetylene (light C₁–C₂ hydrocarbons), along with benzene, toluene, ethylbenzene, and styrene (aromatic hydrocarbons). A procedure is developed to measure the mass fractions of light (C₁–C₂) and aromatic hydrocarbons in the gas phase. The ranges of analytical measurement are 2.9 × 10⁻⁸ to 1.2 × 10⁻¹ mg/mL for light C₁–C₂ hydrocarbons and 3.5 × 10⁻¹¹ to 4.0 × 10⁻³ mg/mL for liquid hydrocarbons. The under conditions of repeatability is 1.9–4.7%.

催化乙苯热解反应产物质量分数的测量程序

摘要

提出了一种在功能化的聚（1-三甲基甲硅烷基-1-丙炔）（PTMSP / N ₂ O）毛细管柱上测定催化乙苯热解反应产物质量分数的技术。带有PTMSP / N ₂ O的毛细管柱可选择性分离甲烷，乙烷，乙烯和乙炔（轻质C ₁ -C ₂烃），以及苯，甲苯，乙苯和苯乙烯（芳烃）。开发了一种程序来测量气相中的轻质（C ₁ -C ₂）和芳烃的质量分数。对于光C ₁，分析测量范围为2.9×10 ^-8至1.2×10 ^-1 mg / mL–C ₂碳氢化合物，液态碳氢化合物为3.5×10 ^-11至4.0×10 ^-3 mg / mL。在可重复性条件下为1.9–4.7％。
