Determination of Butanone Oxime Release in Deketoxime Type Silicone Sealant
Using a headspace bottle as the vulcanization container for deketoxime type silicone sealant,under the condition of adding 10 µL of water and 24 hours of curing,the released butanone oxime was absorbed by internal standard solution within 60 minutes.The sample was detected by gas chromatography and quantified by the internal standard method.The recovery rate of this method was 98.1%-104.2%,and the relative standard deviation(n=10)of the measured value was 1.84%.
