| titleOfInvention | Method for industrially detecting sulfur content in combustible solid acenaphthene |
| abstract | The invention discloses a method for industrially detecting the sulfur content in combustible solid acenaphthene. The detection method comprises the following steps: s1, mixing an acenaphthene sample to be detected, magnesium oxide and a mixed flux with a crucible, and then adding absolute ethyl alcohol until the mixture is solid; the mixed flux is a mixture of anhydrous sodium carbonate and magnesium oxide; s2, igniting the solid, and carrying out melting roasting until the solid is flameless; s3, washing the product obtained in the step S2 by a sodium carbonate solution, and filtering; s4, transferring the filtrate obtained in the step S3 to a volumetric flask, and diluting with deionized water to a constant volume; s5, transferring part of the solution in the step S4, adjusting the pH to 5.5-6.5, adding absolute ethyl alcohol and 3-4 drops of C 6 Na 2 O 6 Indicator, then BaCl 2 And titrating the standard solution until the solution is suddenly changed into red, and obtaining the content of sulfur in the solution according to the formula W% ═ 32 XCXV, so as to obtain the content of sulfur in the acenaphthene sample. The invention does not use heating equipment such as a muffle furnace and the like, does not adopt other large-scale detecting instruments, and simply and conveniently measures the sulfur content in the solid. |
