Abstract:

A method for the qualitative analysis of compositions of anthraquinone working solution (WS)/hydrogenated working solution (HWS) by gas chromatography-mass spectrometry (GC-MS) was developed. The composition of ethylanthraquinone (eAQ) WS/HWS was identified by GC-MS. Then the samples of amylanthraquinone (AAQ) WS/HWS were analyzed by GC-MS. Combined with the reaction mechanism, the composition of AAQ WS/HWS was inferred. The list of the degradation as well as the intermediate products in the industrial synthesis of H2O2 in anthraquinone WS was generated, and the information obtained regarding the composition of the anthraquinone WS/HWS was helpful in identifying and removing the unacceptable degradation products.

Key words: amylanthraquinone, ethylanthraquinone, gas chromatography-mass spectrometry (GC-MS), hydrogenated work solution (HWS), qualitative analysis, work solution (WS)
