Abstract
Alkenes and/or alkadienes are contacted with molecular oxygen and an oxidative dehydrogenation catalyst consisting essentially of silver, molybdenum and oxygen, and at least one promotor selected from the group consisting of phosphorus, arsenic, antimony and bismuth.
Claims4
A process which comprises reacting at least one unsaturated acyclic feed hydrocarbon selected from the group consisting of alkenes and alkadienes having 4 to 10 carbon atoms, with oxygen in contact with a catalyst composition consisting essentially of silver molybdenum and oxygen, and at least one promotor selected from the group consisting of phosphorus, arsenic, antimony and bismuth, with the silver to molybdenum atom ratio being in the range of 0.25:1 to about 10:1, and the promotor to molybdenum atom ratio being in the range of 0.005:1 to 0.5:1 under suitable vapor-phase reaction conditions for the conversion of said at least one unsaturated acyclic feed hydrocarbon to at least one furan compound having the formula ##STR2## wherein each R is individually selected from the group consisting of hydrogen and alkyl radicals having from 1 to 6 carbon atoms, the total carbon atoms in the R radicals being in the range of 0 to 6;
- and recovering at least a portion of the furan compounds thus produced.
