1. The effect of some transition metal salts upon the rate of oxygen-absorption by cis-polybutadiene has been studied; the salts used were acetylacetonates of Co++, Cu++, Fe+++, Mn++ and Ni++. The results show that the relative catalytic activities of these compounds depend on their cationic redox potential in the order: Co++ > Mn++ > Fe+++ > Cu++ and Ni++. It was also found that as the concentration of the salts is increased, the initial rate of oxygen-absorption is also increased, while...

1. The effect of some transition metal salts upon the rate of oxygen-absorption by cis-polybutadiene has been studied; the salts used were acetylacetonates of Co++, Cu++, Fe+++, Mn++ and Ni++. The results show that the relative catalytic activities of these compounds depend on their cationic redox potential in the order: Co++ > Mn++ > Fe+++ > Cu++ and Ni++. It was also found that as the concentration of the salts is increased, the initial rate of oxygen-absorption is also increased, while the maximum rate is only accelerated by Co++, but inhibited by Cu++ and nearly unaffected by Fe+++ and Ni++.2. Comparison has been made between the effects of bivalent cobalt salts: cobalt halides, stearate, and acetylacetonate, upon the oxygen-absorption rate. It was shown that the relative catalytic activities of different halides are similar to each other, but are slightly less active than the two organic salts. The effect of cobalt acetylacetonate on the maximum rate is slightly greater than that of cobalt stearate. Furthermore, it was also found that the maximum rate of oxygen-absorption is proportional to the square root of the concentration of these cobalt salts within the temperature range from 60° to 80℃. The apparent activation energy of the initial stage was found to be decreased by cobalt salts from 20 kcal/mole for the raw polymer to 16 kcal/mole; but that of the maximum rate was not affected, the value of which was 14 kcal/mole.3. The effects of four binary mixtures, acetylacetonates of Co++-Fe+++,Co++-Cu++, Co++-Ni++, and Fe+++-Cu++, on the rate of oxygen-absorption have also been investigated. It was found that with the exception of the Co++-Ni++ system, all the rest showed that the more active component was inhibited by the less active one. Meanwhile, the inhibition effect depended markedly upon the molar ratio of the two components in two different ways, one with an optimum value and the other with a limiting value. Moreover, as the molar ratio was increased to 1 :10, the effect of the Co++-Fe+++ system was synergistic, i.e. the value being greater than additive.

1.比较了乙酰基丙酮Co~(++)、Cu~(++)、Fe~(+++)、Mn~(++)、和Ni~(++)对顺-1,4-聚丁二烯吸氧速率的影响,得到这些化合物的相对催化活性与它们的阳离子的氧化-还原势有关,这两者的顺序完全一致,即 Co~(++)>Mn~(++)>Fe~(+++)> Cu~(++)及 Ni~(++)。同时还发现,随着这些变价金属盐浓度的增大,所有这些变价金属盐均对起始吸氧速率有加速作用,但程度各有不同,即按上述顺序排列。对最高吸氧速率只有钴盐具有明显加速作用,铁和镍盐则几乎没有什么影响,铜盐主要表现为阻化效应。 2.比较了各种卤化钴如二氯化钴、二溴化钴、二碘化钴、硬脂酸钴和二乙酰基丙酮钴对顺-1,4-聚丁二烯吸氧速率的影响。结果表明,所有卤化钴彼此间的相对催化活性几乎没有什么差别,但其活性要略小于两种有机钴盐。至于二乙酰基丙酮钴与硬脂酸钴之间的差别,则对于最高吸氧速率的影响前者略高于后者。此外还发现,当实验温度在60°至80℃范围内时,最高吸氧速率与这三种钴盐浓度的平方根成正比。在所指的温度范围内,这些钴盐可降低起始吸氧阶段的表观活化能(由纯胶的20千卡/克分子降至16千卡/克分子),但不影响最高...

Based on the empirical electron theory, the structure of bond electrons and mognetic moment of Ni-Mn and Ni-Co binary solid solutions are analyzed. The results obtained for magnetic moments are in agreement with the famous experimental curves of Pauling-Plater triongles to the first order appoximation. The variation of the theorefical laffice constont a with composition x agrees also with the experimental a-x curves to the same order of approximation. The transition of the hybrid levels with the composition and the occurrence of short range ordering in certain conditions are explained in terms of the variation of the number of atomic covalent electron.

About 340 samples of the Malan loess (and related sediments) from 55 localities in the middle reaches of the Yellow River were collected and six trace elements-Zn,Cu,Mn,Co,Ni and Mo have been analyzed by atomic absorption spectrophotometry and polarography.The results show that the contents of Zn,Cu,Mn and Ni are lower than their average values in the crust,and close to or slight higher than the abundances in soils.The content of Co is higher than its average in soils,close to the crustal abundance.The...

About 340 samples of the Malan loess (and related sediments) from 55 localities in the middle reaches of the Yellow River were collected and six trace elements-Zn,Cu,Mn,Co,Ni and Mo have been analyzed by atomic absorption spectrophotometry and polarography.The results show that the contents of Zn,Cu,Mn and Ni are lower than their average values in the crust,and close to or slight higher than the abundances in soils.The content of Co is higher than its average in soils,close to the crustal abundance.The content of Mo is the lowest.Maps of trace element distribution in the Malan loess were drawn.Based on the content ranges and analytical errors of each element,coupled with geological backgrounds of loess,five classes (for Zn,Cu,Co,Ni) and four classes (for Mn,Mo) of contents have been expressed separately.And they are examined by histograms showing freqency classes.From the maps of their distribution patterns it can be seen clearly that the contents of trace elements all increase progressively in a direction from northwest to southeast,showing a belt-like distribution.It is interesting that the zonation of trace elements is consistent with that of granulometric compositions of the Malan loess (sandy loess-loess-clayey loess from northwest to southeast).Furthermore,the samples with the lowest values lie at the transitional zone between loess and desert; the samples with the highest values are located in the transition area between secondary loess and loess in the Weihe Valley.Evidently,the distributions of trace elements in the Malan loess are controlled by granulometric compositions,are probably related with mineral composition and bioclimatic condition during loess deposition.These maps are of great significance in evaluating agricultural ultilization of loess and its influence on human health.

应用黄河中游地区约340块马兰黄土(和有关沉积物)样品中Zn、Cu、Mn、Co、Ni、Mo六个微量元素的分析资料,编制了该区黄土微量元素分布图。分布模式图清楚表明,各元素的含量均自西北向东南逐渐增加,并明显地呈带状分布。这分布规律除受黄土粒度成分的控制外,并与区域的矿物成分和黄土堆积时生物气候环境的差异有关。黄土微量元素分布图对黄土区农业利用和人类生存环境评价有重要参考价值。
