摘要
Abstract
The measurement method of active hydrogen content of hydrosilicone oil was established through the reaction of hydrosilicone oil with bromine under acidic condition to generate hydrogen bromide, and the excess bromine reacted with potassium iodide, then the salting out iodine was measured with stan-dard titration of sodium thiosulfate solution. The effects of solvent types, the weight of sample, the amount of bromoacetic acid solution and potassium iodide and the reaction time on the measurement result were investi-gated.关键词
