Gas chromatographic determination of the composition of coal pyridine products
The coking industry produces a wide range of products of the pyridine group from the crude light pyridine bases extracted from the coke oven gas. They include pure pyridine, pyridine solvent, ..cap alpha..-picoline, and the ..beta..-picoline and 2,4-lutidine fractions. The specifications for quality of these products are becoming increasingly stringent. The present methods of determining the quality indices are complex and laborious and do not always reflect the true component composition of the pyridine products. This paper describes the testing of a capillary gas chromatograph for the monitoring and analysis of pyridine products at all stages of their refining. The proposed method permits quantitative identification and adequately accurate determination of the concentraton of pyridine products. 15 references, 6 figures, 4 tables.
