Abstract
Qualitative analysis/quantitative analysis of trimethyl acetyl chloride with its synthesis liquid and research , Trimethyl acetyl chloride was synthesized with trimethyl-acetyl acid and phosphorus trichloride, its synthesis liquid contain:trimethyl-acetyl acid,phosphorus trichloride,trimethyl acetyl chloride,phosphoric acid,trimethyl-acetic anhydride,hydrochloric and other impurity. A model GC112A gas chromatograph equipped with FID/TCD was used .The column is a elastic force quartz capillary tube(φ0.31mm×25m) packed with OV-1. Operating parameters: column temperature programming:70℃ (5min) then 20 ℃ ·min~(-1) to 140℃ (20min);Injecter temperature,150℃;Detector temperature 200 ℃.Analytical of composition in trimethyl acetyl chloride with its synthesis liquid be established.Each main product achieve to baseline isolation with raw material.Loath to part from each other achieve to peak valley isolation with raw aterial.The determination relative errors of quantitative calibration factor were 0.42%,and its relative standard deviation was 0.27%. Useful life of capillary tube column was in progress inspect.Storage condition of test sample was in progress inspect.
