The acetone is used on a large scale in practice as solvent of nitro-cellulose and acetyl-cellulose paints and lacquer, rubber and resins. A spectrophotometric method in the infrared area for direct determination of gas phase of acetone is developed by means of 20 m.gas cuvette. The determination is performed in the specific for the acetone peaks at 1216 cm-1 and 1737 cm-1. With the method could be determined the acetone concentrations of 10 mg/m3 to 2000 mg/m3. For this purpose are worked out different standard scales of the acetone at various length of the gas cuvette. The method is specific in the presence of the most frequently used organic solvents--toluol, ethanol, butanol, mineral turpentine and cyclohexan. Ketones only stand in the way of determination.
丙酮在实际中大规模用作硝化纤维素和乙酰纤维素涂料及清漆、橡胶和树脂的溶剂。借助20米长的气体比色皿开发了一种用于直接测定丙酮气相的红外区域分光光度法。该测定在丙酮特定的1216厘米-1和1737厘米-1处的峰进行。用该方法可测定10毫克/立方米至2000毫克/立方米的丙酮浓度。为此，制定了不同气体比色皿长度下丙酮的不同标准刻度。该方法在最常用的有机溶剂（甲苯、乙醇、丁醇、矿物松节油和环己烷）存在下具有特异性。只有酮类会妨碍测定。
