The y-radiolys:s of 717-trimethyl anionite Br type, HS04- type and NO3- type in dry, wet form or dipped in Corresponding HBr, H2SO4 and HNO3 solutions has been investigated.It shows that anionite HS04- type is more sensitive to y-radiation than the other two. The presence of water increases the rupture of C-N bond, while 7N HN03 can remarkably inhibit the break of C-N bond. There is no relationship between the rupture of C-N bond and OH free radical which can promote the production of weak basic exchangable...

The y-radiolys:s of 717-trimethyl anionite Br type, HS04- type and NO3- type in dry, wet form or dipped in Corresponding HBr, H2SO4 and HNO3 solutions has been investigated.It shows that anionite HS04- type is more sensitive to y-radiation than the other two. The presence of water increases the rupture of C-N bond, while 7N HN03 can remarkably inhibit the break of C-N bond. There is no relationship between the rupture of C-N bond and OH free radical which can promote the production of weak basic exchangable capacity. H atom may hinder the recombination of radicalsformed after rupture of -C-N- bond. The main composition of residue is trimethyl-amine salt mixed with some amount of di methylamine salt. The yield of dimethyl-amine depends on the state of resin and medium. In nitric acid mediam, the yield of dimethylamine is greatly reduced.

本文研究了国产717型三甲胺Br~-型,HSO_4~-型,NO_3~-型绝干、含水及相应浸泡于HBr,H_2SO_4,HNO_3等溶液树脂的γ辐射稳定性。研究表明HSO_4~-型阴离子交换树脂的辐射稳定性最差。γ辐照时,水的存在能加剧C—N键的断裂,而7NHNO_3显著抑制C—N键断裂,OH自由基与C—N键断裂无关但与形成弱碱性交换基团有关。H原子可能影响C—N键断裂后两自由基的重合作用。γ辐照后,残渣主要成份为三甲胺盐并杂有二甲胺盐,二甲胺的产率与树脂的状态,所处的介质密切有关。在硝酸介质中,二甲胺的产率剧烈减低。

Theγ-irradiation stability of polycrystalline glycine (Gly) has been studied by 13C CPMAS, ESR and X-ray diffraction. The 13C chemical shifts and X-ray diffraction data show no change up to 140 kGy dose. Which shows that Gly is stable at this desage. However, the linewidth of I3C resonances increases linearly with the irradiation dose.

用固体高分辨核磁共振~(13)C谱、电子自旋共振谱以及X衍射光谱研究了多晶甘氨酸的γ辐射稳定性。结果表明甘氨酸在0—140kGy辐照剂量范围内是稳定的,而~(13)C共振谱线则随着辐照剂量的增加而线性地增宽。

Anhydrous Ethylenediamine (AEDA) was irradiated in air or nitrogen at ambient tempertures by 60Co 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...

Anhydrous Ethylenediamine (AEDA) was irradiated in air or nitrogen at ambient tempertures by 60Co 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. Re- markable 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 demon- strated. The radiation polymerization of anhydrous ethylenediamine was not reported before.

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H2、CH4、NH3、CH2CH2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H2和CH4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。
