Foreword

GB/T 7717 "Acrylonitrile for industrial use" is expected to be divided into the following sections. --- Part 1. Specification; --- Part 5. Determination of acidity, pH and titration values; --- Part 8. Determination of total aldehyde content spectrophotometry; --- Part 9. Determination of total cyanide titration; --- Part 10. Determination of the peroxide content spectrophotometry; --- Part 11. Determination of iron and copper content spectrophotometry; --- Part 12. Determination of purity and impurity gas chromatography; --- Part 15. Determination hydroxyanisole content spectrophotometry. This section GB/T Part of 107,717. The partial modification using ASTME1784.1997 (2002) "Standard Test Method for Determination of acrylonitrile in total peroxide content of" (English Version), this portion ASTME1784.1997 (2002) of the structural differences in Appendix A. This portion ASTME1784.1997 (2002) of the main differences are. --- Normative documents used in current national standards; --- Applicable concentration range was revised to 0.05mg/kg ~ 1.0mg/kg; --- In the preparation of peroxide-free acrylonitrile, remove the ion exchange resin; distillation of the caustic alkali concentration is reduced to 7% (Mass fraction), remove the water, increasing the anhydrous calcium chloride dehydration step; and clearly the conditions for preparation of activated alumina adsorption method; --- Adjust the color reaction order of addition of reagents; --- Shaking clearly defined time after potassium iodide was 3min, coloration time to 40min; --- Absorption cell specifications from 1cm adjusted 2cm; --- Change the calibration curve method of preparation of each concentration point; --- Increase the use of standard potassium permanganate titration solution of hydrogen peroxide stock solution calibration method; This Part replaces GB/T 7717.10-1994 "industrial use - Determination of acrylonitrile content of peroxides spectrophotometry." This portion of the GB/T 7717.10-1994 main changes are as follows. --- Applicable concentration range was revised to 0.05mg/kg ~ 1.0mg/kg; --- Distillation of the caustic alkali concentration to 7% (mass fraction), anhydrous calcium chloride to reduce the drying time of 4h; increase Using activated alumina prepared without peroxide acrylonitrile; --- Shaking time after potassium iodide was added to 3min; --- Absorption cell specifications from 1cm adjusted 2cm; --- Changing the preparation method and the calibration curve standard solution prepared in the way of each concentration point; --- Increase the use of sodium thiosulfate standard titration solution of hydrogen peroxide stock solution calibration method; Appendix A of this section is an informative annex.
