Catalytic synthesis of thiophene from the gas formed in the semicoking of kukersite shale

Autor: M Ryashentseva, A Myasoyedov, G. E. Voropanov, D Zhogin

Publikováno v: Petroleum Chemistry U.S.S.R.. 30:262-266

Liquid catalyzate containing thiophene has been obtained from the gas formed in semicoking of kukersite shale by means of heterocyclization over an alumina-chromium-lanthanum lanthanum oxide catalyst. The thiophene concentration in the catalyzate is

Thermodynamic analysis of reactions of catalytic heterocyclization of C-hydrocarbons and hydrogen sulphide to alkylthiophenes

Autor: M RYASHENTSEVA, Y BELANOVA

Publikováno v: Petroleum Chemistry U.S.S.R.. 24:229-235

1. 1. Thermodynamic analysis of the reaction between C6-paraffins and olefins of normal and isostructure with hydrogen sulphide at 820°K under ambient pressure on a Cr catalyst, shows that the equilibrium constant of the main heterocyclization react
