Title:
QUATERNARY AMMONIUM SALT, ORGANIC STRUCTURE-DIRECTING AGENT, METHOD FOR PRODUCING QUATERNARY AMMONIUM SALT, CON-TYPE ZEOLITE, METHOD FOR PRODUCING CON-TYPE ZEOLITE, CATALYST, AND METHOD FOR PRODUCING LOWER OLEFIN
Document Type and Number:
WIPO Patent Application WO/2023/249027
Kind Code:
A1
Abstract:
A quaternary ammonium salt that has a specific structure, an organic structure-directing agent that contains this quaternary ammonium salt, and a method for producing a quaternary ammonium salt. Also, a CON-type zeolite that is mixed crystal in which the molar ratio (Si/Al) of silicon (Si) and aluminum (Al) is from 200 to 2000 and that contains 25 mass% or more of polymorph A, a catalyst containing a CON-type zeolite, and a method for producing a lower olefin using this catalyst.
