  hydrate
2,5-Bihydrazino-1,3,4-thiadiazole (2) was synthesized by condensation of 2,5-bimercapto-1,3,4-thiadiazole (1) with hydrazine hydrate, and compound 2 reacted with acyl chloride to give 2,5-biacylhydrazino-1,3,4-thiadiazole derivatives (3a-3e).
      
Gas hydrate is a recently-found new source of energy that mostly exists in marine sediments.
      
In recent years, we have conducted gas hydrate exploration in the South China Sea.
      
The Xisha trough, one of the promising target areas for gas hydrate, is located in the northern margin of the South China Sea, adjacent to several large oil and gas fields.
      
These geochemical anomalies are quite similar to those found in gas hydrate locations in the world such as the Blake Ridge and may be related to the formation and dissociation of gas hydrates.

A new method has been described in this paper for simplifying the anlysis of the liquid phase in salt-water equilibrium systems. According to this method,in a three component system of two salts and water, when the liquid phase is in equilibrium with a solid phase of definite composition such as a salt, or a salt hydrate,etc,only one component has to be determined by analysis,the other two can then be calculated. This is accomplished by first making a solution of water and one salt with definite ratio,...

A new method has been described in this paper for simplifying the anlysis of the liquid phase in salt-water equilibrium systems. According to this method,in a three component system of two salts and water, when the liquid phase is in equilibrium with a solid phase of definite composition such as a salt, or a salt hydrate,etc,only one component has to be determined by analysis,the other two can then be calculated. This is accomplished by first making a solution of water and one salt with definite ratio, and then let the solid phase dissolve in it. Then the problem is reduced to a solubility problem. We have discussed the limitation of applicability and conditions of ensuring accuracy, and also the possibility of extension to systems of more components.In general,the larger the number of components,the more the simplification. This method is applied to the study of the system NaCl-NaAc-H_2O. It has been found to be particular by seutable,as the analysis of Na~+ or Ac~- ions is difficult.

本文考虑了一个简化盐水体系液相成分分析的方法。用这个方法,在二盐和水的三组分体系中,只要和液相平衡的固相是一个定组成的化合物,例如纯盐,盐的某水合物等,都只要分析液相中一个组分就可以算出另外一个组分和水的含量。所以能够如此做,是因为我们可以把三组分体系中的二个组分先用固定比例配成液体,而得与液相平衡的固定出它的溶解度就行了。本文也讨论了这样做法的限制,准确度和它是否可以推广到多元体系。一般说来,组分愈多,也就愈可简化。应用这个方法求研究NaCl-NaAc-H_2O的体系是适宜的,特别是还没有好的分析方法来定Na~+及Ac~-。在本文中,只要分析Cl~-离子。本文求出NaCl-NaAc-H_2O在20℃时的相图。

It was found that methyl chloride hydrate has absorption maxima at 1.493,1.990, 3.032, 4.521, and 6.072μ. and each of these absorption maxima lies bet-ween that of ice and of water as shown in the following table: Modes of Water at Methyl chloride Ice at Vibration 0.5℃ hydrate at 1℃ -3℃ v_1 3389 cm~(-1). 3302 cm~(-1). 3283 cm~(-1).

(1.454μ) (1.493μ) ( 1.495μ) It appeared that during the formation of methyl chloride hydrate, reorien-ration of the water molecules around the methyl chloride molecule takes place,resulting in an ice-like structure.

一氯甲烷水合物在1.45,1.94,2.95,4.66和6.05μ五个区域的红外吸收光谱经用红外光栅分光计分别测定;为便于比较,水和冰相应的红外吸收光谱,亦同时找出。一氯甲烷水合物的红外吸收光谱,与冰的吸收光谱相差甚微,与水的吸收光谱相差很大,可见一氯甲烷水合物形成时,水分子发生了重排作用,氢原子都形成氢键,构成类似冰的结构的结晶体。
