MIXTURE OF REGIOISOMERS OF DEHYDROABIETIC ACID DERIVATIVES, AND PROCESS FOR PRODUCTION THEREOF

摘要

Disclosed is a mixture of regioisomers of dehydroabietic acid derivatives, which comprises at least two dehydroabietic acid derivatives each represented by general formula (I) and independently selected from the group consisting of methylenebisdehydroabietic acid and derivatives thereof. Also disclosed is a process for producing a mixture of regioisomers of dehydroabietic acid derivatives each represented by general formula (I). In the formula, X's independently represent a hydroxy group or an alkoxy group having 1-4 carbon atoms.
