Document Type and Number:
WIPO Patent Application WO/2023/171326
Kind Code:
A1
Abstract:
The present invention provides a method for producing an alkene, the method achieving high conversion rate and high selectivity even in a short period of time at low temperatures. A method for producing an alkene according to the present invention comprises a step in which a solution that contains t-butyl alcohol and at least one alkali-based metal hydroxide selected from the group consisting of alkali metal hydroxides and alkaline earth metal hydroxides, and a halogenated alkane that is represented by general formula (1) and is soluble in t-butyl alcohol are brought into contact with each other in the presence of a cation scavenger that does not have a hydroxyl group. In general formula (1), R1 and R2 are different from each other and each represent a halogen atom or a hydrogen atom; R3 represents a hydrogen atom, the same halogen atom as R1 or R2 represents, or a halogen atom that has a higher bond dissociation energy between itself and a carbon atom than the halogen atom represented by R1 or R2; and R4 represents the same atom as R3 represents, or an alkyl group that may be substituted by an arbitrary halogen atom and has 1 to 3 carbon atoms.
