Method for measuring content of chloride ions in dimethyldichlorosilane hydrolysate

The invention relates to the technical field of analytical testing, and particularly discloses a method for measuring the content of chloride ions in dimethyldichlorosilane hydrolysate. The method comprises the following steps: A, taking an acidic dimethyl hydrolysate under the condition that a hydrolysis process is stable; b, extracting for the first time: separating out acid in the dimethyldichlorosilane hydrolysate by using an extracting agent; c, secondary extraction: continuously adding deionized water and an extraction agent into the separated hydrolysate, fully hydrolyzing, repeating the extraction and liquid separation steps, and measuring the acid concentration omega of the secondary extraction; and C, calculating to obtain the chlorine ion content of the dimethyldichlorosilane hydrolysate. According to the method, hydrochloric acid in the acidic dimethyl hydrolysate is firstly separated out through the extraction agent, then unreacted chloride ions in the hydrolysate are changed into hydrochloric ac
