Title:
PROCESS FOR PRODUCTION OF TRANS CYCLIC POLYPHENOL COMPOUNDS
Document Type and Number:
WIPO Patent Application WO/2011/037073
Kind Code:
A1
Abstract:
A process for selective production of low-molecular trans cyclic polyphenol compounds represented by general formula (3) [wherein L, R1, m, and R' are each as defined in the description]. The process includes a step of reacting at least one phenol compound with at least one aldehyde compound in the presence of a catalyst with the amount of water in the reaction system at the time of initiation of the reaction being controlled within the range of 0 to 50 parts by weight per 100 parts of weight of the phenol compound charged.
