Dehydrated ammonium carnallite was synthesized with bischofite from salt lake and ammonium chloride solution in a 1:1 molar ratio of MgCl2:NH4Cl, dehydrated at 160°C for about 4 h.
      
The decomposition of NH4Cl made a pressure of NH3 at 30.5 kPa to prevent the hydrolysis of ammonium carnallite.
      
A kind of biodegradable material, poly(?-caprolactone-co-lactic acid) [P(CL-co-LA)] was synthesized via the direct melting polycondensation of lactic acid (LA) and ?-caprolactone (CL).
      
The influences of the polycondensation time, and the catalyst type on the intrinsic viscosity of P(CL-co-LA) were also investigated.
      
Compared with lactide ring-opening polycondensation (ROP), the direct melting polycondensation of LA and CL is more practicable and simple.

Measurement of the intensity of total scattering of x-rays by a number of polyatomic gases was made for scattering angles between 15° and 130 ° using an ionization method of recording the scattered intensity. Balanced filters of ZrO2, and SrO were used to separate the MoKa rays and Soller slits were placed in front of the ionization chamber to obtain a definite scattering angle. The gases studied are CL2, CO2, N2O, H2S, CC14 and CHCl3. In each case the absolute values of the scattered intensity were determined...

Measurement of the intensity of total scattering of x-rays by a number of polyatomic gases was made for scattering angles between 15° and 130 ° using an ionization method of recording the scattered intensity. Balanced filters of ZrO2, and SrO were used to separate the MoKa rays and Soller slits were placed in front of the ionization chamber to obtain a definite scattering angle. The gases studied are CL2, CO2, N2O, H2S, CC14 and CHCl3. In each case the absolute values of the scattered intensity were determined by comparison with the scattering from oxygen, the results of Wollan for the latter gas being taken as correct. The experimental results are actually compared with Woo's theory of the scattering of x-rays by polyatomic gases and the agreement seems to be satisfactory.

吴有训氏最近对于多原子气体散射线之理论,曾作详尽的探讨。吴氏得到一个公式,表示由多原子气体所散射之强度,其中一部为相干的散射,另一部为不相干的散射。 以前关于多原子气体散射X-线之实验,为数甚少,且为定性的结果。最近美人Wollan,对于由O_2及N_2(双原子气体)所散射钼的K_3α线之强度,曾作绝对的度量。Wollan的结果,与吴有训氏的理论,甚属相符。本篇目的,在测定由 Cl_2,CO_2,N_2O,H_2S,CCl_4及 CHCl六种气体所散射X-线之强度,每一实验,均与由0_2者互相比较,根据Wollan的结果,每种气体所散射之绝对强度,皆一一量得。所用之入射X-线为钼之Kα线,系藉Ross的平衡过滤法分出。强度之测量,系用一游离方法。散射角度的范围,自15度至130度。每种气体的实验结果,均与吴氏的理论,互相比较,证明理论与实验,甚属相符。在计算时,原子的“构造因数”,系由Hartree的方法算得,一分子中两原子的相隔距离,则由带光谱的结果推得。

An attempt was made by Hodgson to introduce alkyl or aryl group into aromatic ring through the reaction between aryldiazonium chloride [(Ar N_2 Cl)_2·ZnCl_2] and Grignard reagent (RMgX). Among the reaction products, however, he found Ar·Ar, Ar·H, ArN=NAr, ArN=N·R, Ar·X present in various proportions, but no Ar·R as expected. According to the result of an recent investigation of A. N. Nesmeyanov, the thermal decom- position of aryldiazonium fluoroborate afforded aryl cation, while the diazonium salt of...

An attempt was made by Hodgson to introduce alkyl or aryl group into aromatic ring through the reaction between aryldiazonium chloride [(Ar N_2 Cl)_2·ZnCl_2] and Grignard reagent (RMgX). Among the reaction products, however, he found Ar·Ar, Ar·H, ArN=NAr, ArN=N·R, Ar·X present in various proportions, but no Ar·R as expected. According to the result of an recent investigation of A. N. Nesmeyanov, the thermal decom- position of aryldiazonium fluoroborate afforded aryl cation, while the diazonium salt of other types gave aryl radical under the same conditions. The author caused the aryl diazonium fluoroborates to react with the less reactive organo-metallic compounds, namely, ethyl mercuric chloride and diethyl mercury. In contrast to the author's expectation, no ethylaryls were found, but diaryls (Ar·Ar), aryl- chlorides (Ar·C1) and aromatic hydrocarbons (Ar·H), and diaryls, ethyl mercuric fluoroborates, aromatic hydrocarbons and free mercury were found respectively as reaction products. In each case, tar was formed in considerable amount, especially when the decomposition was carried out with diethyl mercury.

Hodgson等曾企圖利用重氮鹽的氯化鋅的複鹽與Grignard試劑反應,希望能將烴基引入芳香環;伹在反應產物中,並無所預期的芳香烴,而有不同此例的Ar·Ar,Ar·H,ArN=N·Ar,Ar·N=N·R及Ar·X。根據最近等對芳香基氟硼酸重氮鹽的研究,證明芳香基氟硼酸重氮鹽在分解時產生烴離子,而與其它重氮鹽產生烴自由基者不同。作者因此利用芳香基氟硼酸重氮鹽及較Grignard試劑的活潑性小的有機汞化合物來代替芳香基重氮鹽的氯化鋅複鹽及Grignard試劑。在反應產物中,並無乙基芳香烴存在;生成的是不同量的Ar·Ar,Ar·H,Ar·Cl等,結果與Hodgson的實驗基本上相同。

Methylchlorosilanes were successfully chlorinated with sulfuryl chloride, when azo-bis-isobuty-ronitrile was used as free radical initiator, giving the corresponding monochlorinated products. The rate of reaction decreased when more Si-Cl bonds were present in the silane to be chlorinated. Increasing the quantity of the initiator increased the rate of reaction.Trimethylchloromethylsilane was also chlorinated with sulfuryl chloride and benzoyl peroxide, both dichloromethyltrimethylsilane and di(chloromethyl)dimethylsilane...

甲基氯矽烷可以在偶氮雙異丁腈的引發作用下,用氯化硫醯進行氯化反應,得到相應的單氯化產物。反應進行速度随着被氯化的矽烷中所合之矽氯鍵增多而減慢。增加引發劑的份量可以增加反應速度。三甲基氯甲基矽烷可以用氯化硫醯與過氧化苯甲醯進行氯化,得三甲基(二氯甲基)矽烷和二甲基二(氯甲基)矽烷。
