Abstract: Discrepancies in the results of chem. analysis of black (kraft) liquors (I) are discussed. The following should be detd. in the original liquor: dry matter, insol. and incombustible portion, NaOH, Na₂CO₃, Na₂S, Na₂SO₃, Na₂S₂O_3, Na₂SO₄, Na₂SiO₃, C, H, O, S. In the ash after combustion the following should be detd.: total ash, insol. part, Na₂SO₄, Na₂CO₃, Na₂SiO₃, and Na₂S. A table is given for calcg. org. matter. The chem. compn. of I shows about 20% O in the dry matter, whereas the literature shows only 10%.
