It is demonstrated that the addition of 5% of water to the non-aqueous solvent for the titrimetric determination of carbon in steel improves the performance of the titration. Modifications to the procedure are proposed which allow the normal titrant, tetra-n-butylammonium hydroxide dissolved in benzene-methanol, to be replaced by an aqueous solution of potassium hydroxide. The proposed procedure has been applied to the analysis of a wide range of standard steel samples.
结果表明，在用于钢铁中碳的滴定测定的非水溶剂中加入5%的水可提高滴定性能。文中提出了对该方法的改进，使得常规滴定剂——溶解于苯 - 甲醇中的四丁基氢氧化铵——可被氢氧化钾水溶液替代。所提出的方法已应用于多种标准钢样的分析。
