Preparing High-Pure Benzene by Chromatography

摘要: 研究了应用气相色谱法制备高纯苯,并对其制备条件的选择及结果进行了讨论.结果表明:采用此法制备的苯其纯度为99.97%,而美国EPA(Environmental Protection Agency)苯标准物质纯度为99.7%.

Abstract: This article focus attention on preparing high-pure benzene through gas chromatogram analyzer,the coice of preparing conditions and its corresponding results. The experiment shows that the purity of benzene obtained through this way is 99.97%,while the purity of standard matter of American EPA benzene is 99.7%.
