Abstract
Abstract Examinations were made on the band spectrum of cuprous chloride based on the Beilstein’s reaction in oxy-hydrogen flame. Determination of chlorine in organic chlorine compounds was attempted by using dimethylformamide containing copper as a solvent and a band peak of 435.4 mμ of cuprous chloride. In order to decrease the effect of C2-Swan band that is produced on combustion of organic compounds, and to increase the sensitivity of cuprous chloride band spectrum, combustion gas was maintained at high oxygen pressure; 1.76 kg./cm2 (25 1b./in2 gauge), and low hydrogen pressure ; 1st, 0.035 kg./cm2 (0.5 1b./in2 gauge), 2nd, 10 cm. water column. γ-BHC was used as the standard and determination was carried out on 11 kinds of organic chlorine compounds, and good results were obtained with samples other than liquid, metal salts, and hydrochlorides. The determinable range for chlorine is 0.005∼3.1 m concentration.
