The method can also be used volumetrically by using 10 c. C. of normal alkali, and titrating the excess with -- acid, using methyl orange as indicator. N i c. C. Of alkali = 0. 0 1 9 gram of carbon bisulphide. CS 2 AND S IN BENZENE. 293 ESTIMATION OF CS 2 AND S IN COMMERCIAL BENZENE. By ED. S. JOHNSON (Journ. Amer. Chem. Soc. , p. 1209). CSy This is converted into potass xanthate by saturated alcoholic potassium hydrate, and is removed from the benzene by repeated washings with alkaline water. ...The xanthate is then converted into the copper compound by slightly acidifying with acetic acid, and precipitating with copper sulphate. The precipi- tate is filtered, washed, and ignited to oxide. One part of oxide = 1. 75 of carbon disulphide. Total Sulphur. 5 c. C. Of the sample are vaporised by a current of hydrogen, they are then burnt in a special apparatus in oxygen, and the products of combustion are absorbed in bottles containing sodium carbonate and bromine solution. This causes a complete conversion of the sulphur into sulphuric acid, which may either be estimated gravimetrically or volumetrically by collecting the products of combustion in a standard solution of sodium hydrate, and, after adding some neutral hydrogen per- oxide, the excess of alkali is titrated back with standard acid.
