METHOD OF SYNTHESIS OF TETRAHYDROTHIOPHENE Russian patent published in 2002 - IPC

Abstract RU 2189981 C1

FIELD: organic chemistry, chemical technology. SUBSTANCE: invention relates to a method of synthesis of tetrahydrothiophene that is used as an odorant of gases and the parent raw for synthesis of different valuable organic substances. Process is performed by hydrogenation of thiophene at T = 240-260 C, P = 0.5-2.0 MPa, feeding rate value 1.7-14.0 mmole of thiophene/h/1 g of tungsten disulfide of the formula WS2 as a catalyst. The method ensures to increase the output of process by 5-fold. EFFECT: improved method of synthesis, enhanced output. 1 tbl, 10 ex
