Abstract An experimental program was carried out to determine the effectiveness of H 2 S/mixed halogen promoters in the oxidative dehydrogenation reaction. Using the butene‐1 to butadiene reaction as an example it was found that while H 2 S or any of the hydrogen halides alone could be used as the promoter, superior conversions and selectivities (80–85%) were obtained when H 2 S was used in admixture with the halogens, preferably HCl and/or HBr. The effect of different catalysts and some processing variables (temperature, space velocity) on the desired reaction will be presented.
