Reactions of lignin – acid suphite pulping In sulphite pulping, two types of reactions, i) sulphonation and ii) hydrolysis, are responsible for delignification.1-3 Sulphonation generates hydrophilic sulphonic acid (-SO3H) groups, while hydrolysis breaks aryl ether linkages between the phenylpropane units, thus lowering the average molar mass and creating new free phenolic hydroxyl (aryl-OH) groups.
