Abstract

1321319 Thiophene SOC NATIONALE DES PETROLES D'AQUITAINE 17 Dec 1970 19 Dec 1969] 60023/70 Heading C2C Thiophene is prepared by heating at 300- 800‹ C. in presence of a heat-stable dehydrogenation catalyst, a gaseous mixture of thiophane, SO 2 and an inert gas. Exemplified catalysts are Cr 2 O 3 /Al 2 O 3 , activated C and Bi- or Co-molybdate/SiO 2 .
