Correction: Deciphering ‘water-soluble lignocellulose’ obtained by mechanocatalysis: new insights into the chemical processes leading to deep depolymerization

Correction for ‘Deciphering ‘water-soluble lignocellulose’ obtained by mechanocatalysis: new insights into the chemical processes leading to deep depolymerization’ by Mats Käldström et al., Green Chem., 2014, 16, 3528–3538. On page 3532, second column, the second paragraph should read: “The last important information that can be extracted from the HSQC spectra is the relative composition of lignin in terms of coumaryl (H), coniferyl or guaiacyl (G) and sinapyl (S) units. To obtain the composition of H, G and S units, the aromatic region of the HSQC spectra (Fig. 3b and 3d) was analyzed. The 1H–13C pairs considered in this estimation are H2/6 (δC/δH, 128.0/7.2 ppm, not detected in the beechwood samples studied here), G2 and S2/6 (the contribution of S ′2,6 included) because of their similar chemical environment.22 Hence, by using the half-value of the volume integral of the correlation signals S2/6 (note that they correspond to two 1H–13C pairs), in addition to the entire integral value for G2, the lignin composition can be estimated in terms of S and G units as given by eqn (2) and (3), respectively. The values for S- and G-contents (Table 2) are correct. The discussion and conclusions remain unchanged.
