本文探讨了提高γ体含量的途径。发见以二氯乙烷为溶剂时γ体含量最高可达22.2%。超过了国际上辐射合成“666”γ体含量17%的最高指标。不论有无附加物存在,在一定的温度范围内γ体含量随着反应温度的升高而下降。根据文献和我们自已的工作,讨论了苯的辐射氯化的反应机制和动力学,碘和氧对链式反应的抑制作用以及过氧化苯甲酰的催化作用。
This article explores ways to increase gamma body content. I found to dichloroethane as a solvent γ body content up to 22.2%. Exceeds the highest international standard of radiation synthesis “666” γ body content of 17% of the highest indicators. Regardless of the presence or absence of addenda, the gamma content decreases with increasing reaction temperature over a range of temperatures. Based on the literature and our own work, the reaction mechanism and kinetics of benzene radiation chlorination, the inhibition of chain reaction by iodine and oxygen, and the catalysis of benzoyl peroxide were discussed.
