摘　　要：对神府大柳塔烟煤及其３００、４００、５５０、７００℃干馏产物，在７５ｇＫＯＨ／３０ｇ试样（ａｄ．）水溶液、氧初压为５．５ＭＰａ或６．０ＭＰａ和２５０℃的条件下氧化２ｈ，其氧化产物水溶酸的产率及其组成随干馏温度的升高而变化，在干馏温度为４００℃时水溶酸的产率达到最大（５４．９６％对ｄａｆ．试样），并采用气相色谱法进行定性、定量分析。Shenfu Daliuta bituminous coal and its carbonized products at 300, 400, 550 and 700℃ were subjected to alkalioxygen oxidation at 250℃ in an aqueous solution of potassium hydroxide (75g KOH/30g samples (ad )) for 2h The yields and compositions of watersoluble acids changed with increacing carbonization temperature At carbonization temperature of 400℃, a maximum yield (54 9%, to daf samples) of watersoluble acid was reached The oxidation products were aoalyzed qualitatively and quantitatively by gas chromatograghy
