    Abstract:
    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.
