The probable molecular structures of PSO3E which came from petroleum sulfoxide were deduced by analyzing IR and GC-MS spectra of PSO3E.

The molecular structures of PSO3E which came from petroleum sulfoxide were analysed by IR and GC MS.

The adsorbing behavior of petroleum sulfoxide levextrel resin for Au (Ⅲ)were determined.

The process of producing fluourescent grade yttrium oxide in hydrochloric acid system using naphthenic acid-petroleum sulphoxide-kerosene as extractant and mixed rare earth oxide rich in yttrium oxide as feed solution was studied.

The properties and principles of the synergistic extracting rare earth(Gd、TB、Dy)by the binary system of P_(507) and petroleum sulphoxide in the medium of hydrochloic acid have been investigated.

This paper studied the performance of the two components of petroleum sulfoxides, PSO3D and PSO3E extracting Au 3+ in HCL medium.

Classical silica column chromatography was used to pre-prepare thepetroleum sulfoxides PSO divided into four parts, then high performance liquid chromatography(HPLC) was used to seperate the third part PSO3.
