Title:
NOVEL METHOD FOR PRODUCING BENZOXAZINE COMPOUND
Document Type and Number:
WIPO Patent Application WO/2022/163555
Kind Code:
A1
Abstract:
The present invention addresses the problem of providing a production method having higher safety and efficiency in a method for producing a target benzoxazine compound that does not create a sudden temperature rise or smoke when introducing the raw material prior to benzoxazine compound generation. Provided as a solution is a method for producing a benzoxazine compound represented by general formula (3), characterized by mixing and reacting a mixture including a bisphenol compound represented by general formula (1) and formaldehydes with an amine compound represented by general formula (2).
