| Abstract: | New active and selective catalysts were prepared by adding different quantities of Te to CdMoO4. These were already selective at low Te levels, but the one with a Cd/Te/Mo ratio of 1/1/1 was specific for butadiene. The catalytic behavior of the Cd–Te–Mo–O system has been correlated mainly with the CdTeMoO6 phase in the region rich in Te and with the CdMoO4 phase with Te as dopant in the region poor in Te.
