Introduction
GB/T 7717 "Industrial Acrylonitrile" includes product standards and supporting method standards for industrial acrylonitrile. In order to facilitate management and use,
It consists of the following parts.
--- Part 1.Specifications. It specifies the product classification, technical requirements and test methods, sampling, inspection rules and standards of acrylonitrile for industrial use.
signs, labels and accompanying documents, packaging, transport and storage.
--- Part 5.Determination of acidity, pH value and titration value. Determination of acidity by chemical titration; pH measurement by pH meter; Potentiometric drop
Determine the titer value.
--- Part 8.Determination of total aldehyde content Spectrophotometric method. It is the reaction of total aldehydes and derivatizing reagents to produce colored anionic dyes.
The absorbance value was measured, and the total aldehyde content was calculated.
--- Part 9.Determination of total cyanide content by titration. The cyanide in the sample is extracted with an alkaline solution of potassium iodide to make it soluble
The total cyanide content was calculated by titration with silver nitrate standard titration solution.
--- Part 10.Spectrophotometric method for the determination of peroxide content. Under the action of acetic anhydride, peroxide reacts with potassium iodide
Yellow iodide ions should be generated, and the content of peroxide is calculated by measuring the absorbance value of the solution.
--- Part 11.Determination of iron and copper content by spectrophotometry. Evaporate the sample to dryness and digest with mixed acid to remove organic matter, and iron
After the ion and copper ions react with the derivatizing reagent respectively, a colored complex is formed, which is measured with a spectrophotometer, and the iron and copper are calculated.
content.
--- Part 12.Determination of purity and impurity content by gas chromatography. is the determination of the purity of acrylonitrile samples by gas chromatography and
impurity content.
--- Part 15.Determination of p-hydroxyanisole content. Including spectrophotometry and gas chromatography, where spectrophotometry uses
The absorbance of the sample was directly measured at 295 nm by an ultraviolet spectrophotometer, and the content of p-hydroxyanisole was calculated; gas chromatography method
The content of p-hydroxyanisole was separated and determined by gas chromatography.
--- Part 16.Determination of iron and copper content by graphite furnace atomic absorption spectrometry and inductively coupled plasma mass spectrometry. of which stone
Ink furnace atomic absorption spectrometry is to measure the absorbance at the characteristic wavelengths of iron and copper after diluting the sample with ethanol.
Calculate the iron and copper content; inductively coupled plasma mass spectrometry is to dilute the sample with ethanol, add the internal standard solution, and use iron and copper.
The characteristic mass of the mass spectrometer was collected, and the iron and copper contents were calculated.
