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 117,717. This Part replaces GB/T 7717.11-1994 and GB/T 7717.14- "industrial use spectrophotometric determination of iron content of acrylonitrile" 1994 "industrial use - Determination of copper content in the acrylonitrile spectrophotometry." This part of GB /7717.11-1994 and GB/T 7717.14-1994 standard T compared to the main changes are as follows. --- Will be integrated into a standard 1994 version of the standard two. To facilitate the operation, according to the main sections of the determination of iron, copper independently written technical content Basically unchanged; --- The name was changed to "industrial use - Part 11. Iron, spectrophotometric determination of copper content"; --- Sampling of copper content determination by the "100g" to 100mL; --- Increased Chapter 3, "Security." This part is proposed by the China Petroleum and Chemical Corporation. This part of the National Standardization Technical Committee Petrochemical Chemical Club (SAC/TC63/SC4) centralized. This section drafted by. China Sinopec Shanghai Petrochemical Company Limited. The main drafters of this section. Quling Di, Tang Jianzhong, Chen Huili, Zhoukui Liang, Chen Huan. This part of the standard replaces the previous editions are. --- GB 7717.11-1987, GB/T 7717.11-1994; --- GB 7717.14-1987, GB/T 7717.14-1994. Acrylonitrile for industrial use Part 11. Determination of iron and copper content Spectrophotometry

1 Scope

This section provides Acrylonitrile for industrial use iron, copper content measured by spectrophotometry. This section applies to an iron content greater than 0.05mg/kg, copper content in the range of (0 ~ 1) mg/kg for industrial use - a sample of iron, copper Determination of. When the iron content more than 100 times the copper content, the determination of copper will produce interference.
