By heat treatment study, extraction experiments and powder photography, the differential thermal effects occuring below 250°of three amorphous sulfides of antimony are inter- preted in this paper. At about 220°, all the three amorphous sulfides produce crystalline Sb_2S_3. In the neighborhood of 160°, the pentasulfide and tetrasulfide segregate into easily extractable sulfur and amorphous Sb_2S_3. The latter change has been identifid in the main with the following reaction: 1/xS_x→1/8S_8+~3 kcal. On the basis of the above identification, the pentasulfide and tetrasulfide prepared from Na_3SbS_4·9H_2O are probably complex systems of [Sb_2S_3+S_μ+S_λ] and of [Sb_2S_3+S_μ] respectively. The fact that a synthetic sample containing 91% amorphous Sb_2S_3 and 9% Sμ gives essentially the same differential thermal diagram as the pentasulfide and tetrasulfide strongly supports the proposed model. According to Currie, Bunsen's pentasulfide contains no easily extractable sulfur. However, Bunsen's pentasulfide may not be a chemical individual either, inasmuch as it produces easily extractable sulfur at about 160°. In the light of the proposed theory, Bunsen's pentasulfide is probably a complex system of [Sb_2S_3+2S_μ]. The differential thermal diagram of the pentasulfide is probably a pertinent reference to its quality.

銻的三種無定形硫化物在250°以內的差熱效應,曾於熱處理實驗、硫的提取實驗與粉末法的結果的配合下取得了鑑定與解釋。五硫化二銻與四硫化二銻在160°附近進行一放熱的、析出容易脫去的硫的析硫作用,並在220°附近進行無定形Sb_2S_3的晶化作用。析硫作用主要是下列變化: 1/xS_x→1/8S_8+~3千卡而從硫代銻酸鈉製得的、含有~8%容易脫去的硫的五硫化二銻樣品基本上是下列複雜的無定形體系 [Sb_2S_3+S_μ+S_λ]Currie按照Bunsen方法製得的、不含容易脫去的硫的五硫化二銻樣品可能是下列複雜的無定形體系 [Sb_2S_3+2S_μ] 合成樣品[Sb_2S_3+S_μ]的差熱曲線與所謂五硫化二銻和四硫化二銻者並無二致。文中最後還曾指出了從差熱曲線來檢驗五硫化二銻質量的可能性等。

The overall reaction of chlorination of O,O-diethyldithiophosphoric acid,giving O,O-diethyl-thiophosphoryl chloride and sulphur monochloride,is found to consist of following successivesteps:One of the reaction intermediates,bis-(diethylthionophosphate) disulphide,has been isolatedand identified,and another intermediate,the diethyhhionophosphate sulphur chloride,whichis too unstable to be isolated,has been identified indirecdy through the following reaction:(?)A crystalline solid appearing in the course of the chlorination is found to be bis-(diethyl-thionophosphate) trisulphide,which in turn,upon further chlorination,is converted similarlyinto O,O-diethylthiophosphoryl chloride and sulphur monochloride.The present study indicatesthat the formation of the trisulphide depends presumably upon the reaction temperature.In view of the fact that the diethylthionophosphate sulphur chloride decomposes uponheating into free sulphur and O,O-diethylthiophosphoryl chloride,the reaction is exploited byauthors in the hope of simplifying the process in the manufacturing of O,O-diethylthiophosphorylchloride.The result has shown that the reaction cannot be controlled conveniently.With sul-phur monochloride as chlorinating agent,however,the reaction proceeds satisfactorily.

In the present investigation, water in bleaching powder was found to play a leading role in determining the stability of the latter. In order to compare the stability of various samples of bleaching powder, we determined the content of the available chlorine before and after a sample kept in a small glass-stoppered tube at 90℃ for 8 hours. The ratio of residual to the original content of available chlorine when expressed in percentage is defined as the index of stability.The samples of bleaching powder and raw calcium hypochlorite investigated in our work contain-ed in the main the following components: Ca(Ocl)_2(S), Ca(OCl)_2·3H_2O(S), CaCl_2·6H_2O(S)and CaCl_2·Ca(OH)_2·H_2O(S). When bleaching powder or raw calcium hypochlorite was thoroughly dried under a vapor pressure of 0.1 mm. Hg at 25°, two of the components were dehydrated according to the following reactions (Figure 5): Ca(OCl)_2·3H_2O(S) = Ca(OCl)_2(S) + 3H_2O(~5mm. Hg) CaCl_2·6H_2O(S)=CaCl_2·H_2O(S) + 5H_2O(~1.0 mm. Hg) and the index of stability attained 100% (Figures 6 and 7). Water which can be removed from a sample under the above conditions is defined as removable water. By the control of amount of the removable water in a sample, the index of stability can be made to vary between 0 to 100%.If we take the percentage of the available chlorine decomposed in an hour at 90 as the rate of decomposition (D %/hr.), the latter seemed to vary linearly with the amount of removable water (W %) (Figure 8). When the samples were heated in a stoppered tube to 90° from 25°, the removable water probably redistributed according to the following scheme: xCa(OCl)_2(S) + y Ca(OCl)_2·3H_2O(S) + z CaCl_2·6H_2O(S) 25° xCa(OCl)_2(S) + (y + (5z)/3) Ca(OCl)_2·3H_2O(S) + z CaCl_2·H_2O(S) 90° Inasmuch as the thoroughly dried samples did not decompose considerably even at 90°, the decomposition of OCl~- seemed to take place almost exclusively in the phase Ca(OCl)_2·3H_2O(S). The linear relationship of D vers. W indicated that the decomposition rate of a sample varied linearly with its content of the component Ca(OCl)_2·3H_2O(S) at 90°. In the light of the above results, an explanation was proposed to account for the decomposition of bleaching powder under the conditions of storage.

本工作肯定,水在漂白粉的稳定性问题中具有极其重要的作用.漂白粉和漂粉精样品在0.1毫米汞柱的蒸气压下可脱去的水称为可脱水.在90°下八小时后样品中有效氯量占原有效氯量的百分数称为其稳定度.稳定度测值指出,样品的可脱水率从0%递增时,其稳定度则从100%递减至0%.根据吸水率-蒸气压图等数据,样品的可脱水主要分布在物相Ca(OCl)_2·3H_2O(S)和CaCl_2·6H_2O(S)中,而在90°下,全部可脱水则集中至前一物相.样品有效氯成分的分解主要在Ca(OCl)_2·3H_2O(S)中,而在Ca(OCl)_2(S)中分解很少.稳定度的数据指出,在90°下,样品有效氯分解率与其中可脱水率成正比,从而亦与其中物相Ca(OCl)_2·3H_2O(S)的含率成正比. 根据上述,作者并从生产实践的意义讨论了漂白粉的稳定性问题.
