The liquid-liquid equilibrium data for ternary systems: propionic acid-ethyl aceta te-water at 15℃, butyric acid-ethyl acetate-water at 15° and 30℃, and mixed acids (acetic, propionic, butyric acid)-ethyl acetate-water at 15℃ were determined. Thevapor-liquid-equilibrium data for binary systems of acetic-propionic acid, propionicbutyric acid, and acetic-butyric acid under normal pressure were also given. The authors regarded that the non-ideal behavior of vapor-liquid equilibrium is mainly attributed to the vapor...

The liquid-liquid equilibrium data for ternary systems: propionic acid-ethyl aceta te-water at 15℃, butyric acid-ethyl acetate-water at 15° and 30℃, and mixed acids (acetic, propionic, butyric acid)-ethyl acetate-water at 15℃ were determined. Thevapor-liquid-equilibrium data for binary systems of acetic-propionic acid, propionicbutyric acid, and acetic-butyric acid under normal pressure were also given. The authors regarded that the non-ideal behavior of vapor-liquid equilibrium is mainly attributed to the vapor phase association between molecules, and they derived a correlative equation for calculating the vapor-liquid equilibria in case of molecular association. The vapor-liquid equilibrium data for acetic-butyric acid calculated by the equation derived check with the experimental result.

测定了15℃时丙酸,15℃及30℃时丁酸和15℃时乙、丙、丁混合酸在乙酸乙酯和水中的液-液相平衡数据。也测定了乙酸-丙酸,丙酸-丁酸及乙酸-丁酸三个二元系统在760毫米汞柱压力时的汽-液平衡。我们认为汽-液平衡的非理想主要是由于汽相分子的缔合。于是推导了计算分子缔合时的汽-液平衡关系式,推算的乙酸-丁酸二元系统的汽-液平衡数据和实验结果相符合。

Low-boiling phenols in low-temperature coal tar are important chemical raw materials. For the identification and determination of the individual phenol boiling below 210℃ in the low temperature coal tar, the methods of gas chromatography, liquid-liquid chromatography followed by ultra-violet analysis and fractional distillation followed by infrared analysis were evaluated and compared. For the same sample, the maximum deviation derived by these three methods was all within 2%. Although the first method was the...

Low-boiling phenols in low-temperature coal tar are important chemical raw materials. For the identification and determination of the individual phenol boiling below 210℃ in the low temperature coal tar, the methods of gas chromatography, liquid-liquid chromatography followed by ultra-violet analysis and fractional distillation followed by infrared analysis were evaluated and compared. For the same sample, the maximum deviation derived by these three methods was all within 2%. Although the first method was the most rapid one, but the last two gave more comprehensive results. For example, with the gas chromatography method, m-cresol, p-cresol and 2,6xylenol could not be separated, but with the last two methods the composition of each isomer could be determined.

随着煤炼油工业的发展,煤焦油中的酚类,特别是低級酚,作为化工原料的利用很重要,我們应用(1)气液色譜法,(2)液液色譜与紫外光譜法結合及(3)精餾与紅外光譜法結合三种不同方法对210°以前的低級酚进行了各种异构体的成分分析,比較分析結果:三种方法对同一样品进行分析时,最大絕对誤差在2%以内,其中以气液色譜法最为快速,液液色譜法次之,精餾-紅外光譜法費时間較多;但后二种方法所得数据較完全。例如对甲酚,問甲酚及2,6-二甲酚用气液色譜法不能分开,而利用后二种方法則可以分别得到各个单体酚的百分含量。

The ternary system of dibutyl sulfoxide (DBSO)--phosphoric acid--water hasbeen studied at 40℃. The binodal curve of the system was determined by theturbidity method and the tie line data were obtained by analyses of the H_3PO_4concentrations of both phases at equilibrium. Bath Hand and Othmer--Tobias methods were tried to find the position ofplait--point and found to agree with each other. From the shape of binodal curve and distribution line, DBSO may be consideredto possess better extraction properties than...
