Abstract: Provided is a technology for efficiently manufacturing 1,3-butadiene from 1,4-butanediol or 3-buten-1-ol in a reaction condition with a high conversion rate. A catalyst for manufacturing 1,3-butadiene, contains: ytterbium oxide as an active component for generating 1,3-butadiene from 1,4-butanediol or 3-buten-1-ol. In addition, a manufacturing method of 1,3-butadiene, includes: a step of obtaining a fluid containing 1,3-butadiene by bringing at least one of 1,4-butanediol and 3-buten-1-ol into contact with the catalyst for manufacturing 1,3-butadiene.

Abstract: Provided is a technique of producing isoprene from 3-methyl-1,3-butanediol or 1,3-butadiene from 1,3-butanediol by using a single catalyst. A catalyst produces a conjugated diene containing zirconium oxide and calcium oxide in order to produce isoprene by removing two water molecules from one 3-methyl-1,3-butanediol molecule or produce 1,3-butadiene by removing two water molecules from one 1,3-butanediol molecule. Furthermore, a method for producing a conjugated diene includes a step of obtaining a fluid containing a conjugated diene that is isoprene or 1,3-butadiene by bringing a fluid containing 3-methyl-1,3-butanediol or a fluid containing 1,3-butanediol into contact with the catalyst for producing a conjugated diene as a single catalyst so as to cause a dehydration reaction to proceed.

Abstract: Disclosed is a method for producing 1,3-butadiene and/or 3-buten-2-ol from 2,3-butanediol with high selectivity without using a radioactive substance. The method for producing 1,3-butadiene and/or 3-buten-2-ol comprises the step of dehydrating 2,3-butanediol in the presence of scandium oxide. The method enables the production of 1,3-butadiene and/or 3-buten-2-ol from 2,3-butanediol with high selectivity without using a radioactive substance.
