摘要

以气相色谱（GC）、气相色谱-质谱（GC-MS）、质谱（MS）和傅立叶变换红外光谱（FTIR）等手段研究了室温下空气和氮气条件下无水乙二胺的 γ 射线辐射效应。分析发现，无水乙二胺在 γ 射线作用下不仅生成了H,2,、CH,4,、NH,3,、CH,2,CH,2,等气体产物和一些液态挥发性产物，而且在液态剩余试样中还生成了多种聚合的胺类产物。相同条件下，气体产物H,2,和CH,4,的量均随剂量的增大而增加。两种气氛中辐射降解和聚合产物的量均很显著，其中在氮气气氛中尤为明显，显示无水乙二胺的 γ 辐射稳定性较差。无水乙二胺的辐射聚合效应尚未见相关文献报道。

Abstract

Anhydrous Ethylenediamine (AEDA) was irradiated in air or nitrogen at ambient tempertures by ,60,Co γ-rays. The radiation degradation products were analyzed by means of GC, GC/MS, MS and FT-IR, etc. Notable gaseous products such as hydrogen, methane, ethylene, ammonia, and some volatile liquid state radiolysis products as well, were examined, and many kinds of polymerized products were detected in the liquid remain sample. It was found that under certain conditions both the hydrogen and methane contents of the products increased with dose. Remarkable effects of radiation degradation and radiation polymerization were observed, and even severe effects were found in nitrogen ambience. Therefore, a worse γ-irradiation stability of anhydrous ethylenediamine was demonstrated. The radiation polymerization of anhydrous ethylenediamine was not reported before.
