    摘要: Forming a diene includes contacting a reactant including at least one of a cyclic ether and a diol with a heterogeneous acid catalyst to yield a reaction mixture including a diene. The heterogeneous acid catalyst includes at least one of a Lewis acid catalyst, a supported Lewis-acid catalyst, a Brnsted acid catalyst, a solid acid catalyst, a supported phosphoric acid catalyst, and a sulfonated catalyst. The dehydration of cyclic ethers and diols with high selectivity to yield dienes completes pathways for the production of dienes, such as isoprene and butadiene, from biomass in high yields, thereby promoting economical production of dienes from renewable resources.
