Kraft lignins can be precipitated and extracted from the black liquor in a two-step acidification process. First, carbon dioxide is used to reduce the pH of the liquor till 9–10, and about 75% of the lignin is precipitated as a sodium salt . For further purification, this lignin is suspended in water and acidified with H2SO4 to a pH lower than 3. The commercial Kraft lignins are generally sold in the sulphonated form or as lignin amines. The physical properties for softwood Kraft lignins and softwood lignosulphonates can be found elsewhere . Lignosulphonates (M.W. 20,000–50,000) have higher molecular weight and lower content in free phenolic hydroxyl groups than Kraft lignins (M.W. 2000–3000). The content in free phenolic hydroxyl groups of Kraft lignins is especially rich with values around 3.1meqg−1 . This functional group plays an important role in the dissolutionof macromolecules. 生物偏有機(jī)化學(xué)方向 |
