石油磺化结焦物结构表征及分析

Characterization and analysis of petroleum sulfated coking structure

采用红外光谱仪对提纯前后的糠醛抽出油磺化结焦物进行红外光谱分析,分析红外光谱图得到结焦物是由砜类、多磺酸和未磺化油组成的复杂混合物。对结焦物的分析有利于控制合成高品质石油磺酸的过程。

Infrared spectroscopy was to extract the sulfonated coking material of furfural oil before and after purification by infrared spectroscopy.The infrared spectrum was analyzed to obtain a comlex mixture of sulfone,polysulfonic acid and unsulfonated oil.Analysis of the coking material facilitates the process of controlling the synthesis of high quality petroleum sulfonic acid.
