| titleOfInvention | Method for Detecting Total pH and Chloride Ion Content of Vinyl Chloride Monomer |
| abstract | The invention discloses a vinyl chloride monomer sampling device, which comprises a sample bottle, a protective cover and a sampling valve. Also disclosed is a method for detecting the total pH and chloride ion content in the vinyl chloride monomer, the detection sample preparation device used includes the vinyl chloride monomer sampling device of the present invention. The advantages are: 1) The safety of the vinyl chloride monomer sampling operation is improved. 2) It is conducive to the guarantee of sample representativeness and authenticity, and is conducive to improving the accuracy of test results. 3) The device is easy to operate and realizes convenient sampling of vinyl chloride monomer. 4) For the first time, it is proposed to directly extract hydrogen ions, hydroxide ions and chloride ions by magnetic stirring in the sampling container of the present invention, and discharge the vinyl chloride monomer after gasification, and the remaining solution adopts potentiometric titration and back titration A method for detecting the total pH and chloride ion content in the sample. 5) The test results can truly reflect the total pH and chloride ion content in the vinyl chloride monomer. |
