Abstract
By pulping Eucalyptus regnans by the kraft process, acidifying the black liquor, and fractionating the product, a thiolignin has been prepared in a pure state.
Thiolignin reacts with diazomethane to yield a trimethyl derivative, and with dimethyl sulphate to yield a hexamethyl derivative.
Thiolignin, trimethylthiolignin, and hexamethylthiolignin react with acetic anhydride in pyridine to yield respectively hepta-, tetra-, and mono-acetyl derivatives.
The data obtained are consistent with the formula C52H35O10.(OCH3)9.C(CH3)OH.(CHOH)3.CH = C(OH).OH.SH.
