METHOD OF CLEANING SULPHATE TURPENTINE FROM SULPHUR COMPOUNDS Russian patent published in 2013 - IPC C09F3/00 B01J21/06 B01J23/44

Abstract RU 2485154 C1

FIELD: chemistry.

SUBSTANCE: invention can be used in organic synthesis and pharmacology. The method of cleaning sulphate turpentine from sulphur compounds involves preheating sulphate turpentine to temperature of 70-80°C and bringing it into contact with a catalyst at temperature of 60-90°C and initial hydrogen pressure of 0.7-0.9 MPa. The catalyst used is a support - highly porous cellular blocked material based on alpha-Al₂O₃ with an active substrate made from sulphated zirconium dioxide in amount of 7.7-8.0 wt %, and a catalytically active component - palladium 0.18-0.2 wt %.

EFFECT: invention reduces residual content of sulphur compounds in sulphate turpentine and simplifies the cleaning process.
