Aromatic hydrocarbons — Determination of sulphur content — Pitt-Ruprecht reduction and spectrophotom...
Relates to products boiling below 200 °C. Directly applicable to contents of 0.1 mg/kg to 30 mg/kg. Higher contents may be determined by a suitable dilution of the sample. Alkylsulphones, arylsulphonic acids and arylsulphonates give incomplete recovery of sulphur. Reduction of the sulphur compounds to nickel sulphide with Raney nickel. Stripping of the hydrogen sulphide in hydrochloric acid…
