2',4,4''-m-terphenyltriols and fungal strain used to make same |
摘要 |
A. parasiticus is employed to hydroxylate 2'-hydroxyterphenyl compounds to terphenyltriols, which can be used to form branched polycarbonates. The hydroxylation reaction is enhanced by maintaining a sufficient amount of a carbon source in the culture medium-reaction medium to maintain the ammonium level below 300 ppm. during the bioconversion phase. Employment of a mutant strain of A. parasiticus which was isolated following ultraviolet light mutagenesis to reduce its tendency to produce aflatoxins is preferred.
