ジエン化合物の製造方法
Document Type and Number:
Japanese Patent JP6684635
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a process for efficiently producing a corresponding diene compound from a 1,3-diol type raw material in which the formation of a byproduct that is impossible to be reused as a raw material, is small.SOLUTION: Provided is a process for producing diene compound in which a first dehydration step of producing an unsaturated alcohol from a diol compound represented by formula (1) by using a composite metal oxide having defect fluorite type crystalline structure or pyrochlore type crystalline structure, and a second dehydration step of carrying out dehydration reaction of the unsaturated alcohol in the presence of a dehydration catalyst comprising at least one selected from a metal phosphate, a metal condensed phosphate, a metal hydrochloride, an oxide of a typical metal or an inorganic acid to produce a diene compound, are implemented.SELECTED DRAWING: None
