| Abstract: | In this paper the phenol contents in coal-tar are determi(?)ed by the re- fractive index method.The result of the enperiments shows the phenol co- ntents in coal-tar are linearly related to the refractive index.The phenol contents in coal-tar are determined respectively by using themethods of al- kali increase and refraltive index.By comparision,the error is kept within 2%. |

| Keywords: | refractive index coal-tar phenols contents methods of alkali increase |
