Document Type and Number:
WIPO Patent Application WO/2023/171274
Kind Code:
A1
Abstract:
The purpose of the present invention is to provide a method of obtaining halogenated alkenes with a high degree of selectivity from immediately after reaction initiation using an inexpensive catalyst. A halogenated alkene production method according to the present invention includes a step in which a halogenated alkane that has four or fewer carbon atoms and contains a fluorine atom is brought into contact with coal ash to induce the dehydrohalogenation of the halogenated alkane.
