The acetylacetone method was used to detect formaldehyde in leather products under wavelength of 412 nm after a color development reaction of acetyl acetone and formaldehyde occurred at (40±2)℃ water bath for (30±5)min. The influence of adding sequence of acetylacetone and the extract on the formaldehyde content was studied. The results indicated that the variation of detection data were indistincrive when different adding sequence was employed.%采用乙酰丙酮法在波长为414nm、乙酰丙酮与甲醛于（40±2）℃水浴中显色反应（30±5）min，测定皮革制品中的甲醛含量。研究了乙酰丙酮及馏出液的不同加入顺序对皮革制品中甲醛含量测定的影响，结果表明两种移取顺序对最终结果影响不大，且未发现没有明显规律。
