| Abstract: | ABSTRACT The overall objective, of this study is to develop an electrochemical method, that will be complementary to the existing spectroscopic methods, for the characterization of sulphur compounds in coal extracts. Beypazan lignite was used in this study. Supercritical interaction between coal and ethyl alcohol/NaOH (or Ca(OH2) ) was carried out using a microreactor of 15 ml capacity. Liquid products obtained were separated by liquid chromatography in a glass column have been determined and these provided a ground for the identification of various sulphur functional groups in coal liquids obtained from supercritical interaction between a lignite and ethyl alcohol/NaOH or ethyl alcohol/Ca(OH) 2 or ethyl alcohol. Organic sulphur compounds determined by this method were dibenzydisulphide, dibenzothiophene and tiophenol |
