| Abstract: | The analytic conditions are defined as; the platinum wire is used as catalyst, the sample burns in oxygen; the amount of sample is 10 mg; the amount of 6% H2O2 is 10 mL and the amount of 0. 5% KOH is 2 mL. By use of this method, twenty minutes are only required for analysis (convention-al method requires l hour) ; the instruments and agent are general-service. Its average error is 0. 015% , its average deviation is 0. 05%. The problem of the terminal control of reaction in the preparation of benzaldehyde using benzyl chloride is solved by this method. |
