Method for determining content of hydrogen chloride in chloroethylene carbonate by adopting non-aqueous automatic potentiometric titration method

The invention discloses a method for determining the content of hydrogen chloride in chloroethylene carbonate by adopting a non-aqueous automatic potentiometric titration method, which belongs to the technical field of analytical chemistry, and comprises the following steps: firstly adding excessive silver acetate solution and hydrogen chloride to generate silver chloride precipitate, then back titrating excessive silver acetate by using perchloric acid standard solution, and determining the content of hydrogen chloride in chloroethylene carbonate on the basis of potential jump. An automatic potentiometric titrator-non-aqueous pH electrode is adopted to confirm a titration end point, and the mass fraction of hydrogen chloride in a to-be-tested sample is calculated according to the volume of a perchloric acid standard solution consumed by a blank test and a sample solution, so that the problem of high result caused by hydrolysis of titration of chloroethylene carbonate in an aqueous solution is solved; and the
