摘要
丙烯腈中的过氧化物含量对于聚丙烯腈基碳纤维的生产至关重要。不含过氧化物的丙烯腈被用作检测丙烯腈过氧化物含量的空白溶液，其储存条件对检测非常重要。当然，存放一段时间后，丙烯腈中过氧化物含量的变化会对碳纤维的生产产生影响。为了研究储存条件对无过氧化物丙烯腈和丙烯腈中过氧化物的影响，分别研究了在冰箱和室温下的变化。研究表明，在低于 20 °C 的温度下储存 3 个月，几乎不会影响无过氧化物丙烯腈或丙烯腈的使用。所获得的实验结果对实际生产和检测很有帮助，可以提高检测的准确性和生产的稳定性。
Evaluating storage conditions on the effect of peroxide content in acrylonitrile
Bewertung der Lagerungsbedingungen und der Auswirkungen des Peroxidgehaltes in Acrylnitril
The content of peroxide in acrylonitrile is critical for the production of polyacrylonitrile-based carbon fibers. Peroxide-free acrylonitrile is used as a blank solution for testing the peroxide content of acrylonitrile, which storage conditions are important to the test. Of course, for the change of peroxide content in acrylonitrile stored for a period of time has an effect on the production of carbon fiber. In order to study the effect of storage conditions on peroxide in peroxide-free acrylonitrile and acrylonitrile, the changes at refrigerator and room temperature were studied, respectively. Studies have shown that storage at temperatures below 20 °C for 3 months hardly affect the use of either peroxide-free acrylonitrile or acrylonitrile. The experimental results obtained are useful for practical production and testing, which can improve the accuracy of testing and stability of production.
期刊介绍：
Materialwissenschaft und Werkstofftechnik provides fundamental and practical information for those concerned with materials development, manufacture, and testing.
Both technical and economic aspects are taken into consideration in order to facilitate choice of the material that best suits the purpose at hand. Review articles summarize new developments and offer fresh insight into the various aspects of the discipline.
Recent results regarding material selection, use and testing are described in original articles, which also deal with failure treatment and investigation. Abstracts of new publications from other journals as well as lectures presented at meetings and reports about forthcoming events round off the journal.
