Studies on the Formation of Benzanthrones in Alkaline Anthraquinone Pulping
Karhunen, Pirkko,Brunow, Goesta
, p. 945 - 948 (2007/10/02)
Loss of anthraquinone (AQ) in alkaline pulping is partly attributed to irreversible reactions of AQ or AQ-derived compounds with lignin fragments. 3-(4-Hydroxy-3-methoxyphenyl)benzanthracen-7-one, 3-(4-hydroxy-3,5-diemethoxyphenyl)benzanthracen-7-one and 3-(4-hydroxyphenyl)benzanthracen-7-one have been synthesized and their formation in reactions of isolated lignins has been studied. 2-(4-Hydroxy-3-methoxyphenyl)anthracene-9,10-dione (2-vanillylanthraquinone) has also been prepared.
