Fig. 3From: Stereo-preference in the degradation of the erythro and threo isomers of β-O-4-type lignin model compounds in oxidation processes III: in the reaction with chlorine- and manganese-based oxidantsTime courses of the changes in the recovery yields of compounds 1E and 1T, when either compound was individually or both compounds were together treated in the chlorite system at a pH of: a 13.3 and 70 °C, b 6.3 and 70 °C, or c 1.0 and 70 °C. Compound 1E: filled circle, filled diamond, filled square, filled star; compound 1T: open circle, open diamond, open square, open star; in the individual reaction of compound 1E or 1T: filled circle, filled diamond, filled square, open circle, open diamond, open square; in the reaction of both compounds 1E and 1T together: filled star, open starBack to article page
