A method for preparing the high acid-consuming-capacity dried aluminium hydroxide powder by the use of alum and soda or other alkali substance as raw material is described. 1) The best results were obtained by using soda as raw material for preparing the alkali solution. 2) The alum solution was added to the alkali solution until pH 5.5-6.5 was reached. 3) The sulfate was removed almost completely by washing with potassium bicarbonate solution(0.4%) before drying. 4) The aluminium hydroxide gel can...

A method for preparing the high acid-consuming-capacity dried aluminium hydroxide powder by the use of alum and soda or other alkali substance as raw material is described. 1) The best results were obtained by using soda as raw material for preparing the alkali solution. 2) The alum solution was added to the alkali solution until pH 5.5-6.5 was reached. 3) The sulfate was removed almost completely by washing with potassium bicarbonate solution(0.4%) before drying. 4) The aluminium hydroxide gel can be dried completely under 100-105℃(ca. 6 hrs.) without influencing the antacid activity. 5) The highest acid-consuming-capacity of the dried powder of aluminium hydroxide gel(free from any free alkali) was determined to be 315.9 ml, i.e. one gram dried sample will neutralize 315.9ml 0.1N HCl.

1.以明礬液倒入碳酸钠溶液中,混合液之酸度须控制为pH6(±0.5)。 2.所得膠体,先用普通水洗滌,继用0.4%碳酸氢钾溶液在抽氣漏斗上洗滌。除去硫酸鹽之手續须一次完成之,烘乾以後即不能重行处理,否则,制酸力急速下降。 3.乾燥可控制在90—110℃(约6—10小时),大量烘乾时应注意湿空氣之排出。 4.产品的制酸力一般为250—280毫/克,最高达315.9毫升/克;硫酸鹽之含量远低於药典规定;游离鹼亦远低於苏联药典之规定。

γ-(Δ~1-Cyclohexenyl)-γ-ketobutyric acid was prepared in an experiment by action of suc- cinic anhydride on cyclohexene with aluminium chloride as catalyst. Meanwhile other cata- lysts of the Lewis acid type, such as ferric chloride and stannic chloride, were also tried, but the results were not satisfactory. In reducing γ-(Δ~1-cyclohexenyl)-γ-ketobutyric acid to γ- (Δ~1-cyclohexenyl) butyric acid, both Wolff-Kishner's method and Huang Minlon's modifica- tion were experimentally employed, the result being...

γ-(Δ~1-Cyclohexenyl)-γ-ketobutyric acid was prepared in an experiment by action of suc- cinic anhydride on cyclohexene with aluminium chloride as catalyst. Meanwhile other cata- lysts of the Lewis acid type, such as ferric chloride and stannic chloride, were also tried, but the results were not satisfactory. In reducing γ-(Δ~1-cyclohexenyl)-γ-ketobutyric acid to γ- (Δ~1-cyclohexenyl) butyric acid, both Wolff-Kishner's method and Huang Minlon's modifica- tion were experimentally employed, the result being unexpectedly in favor of the former. The final step of intramolecular cyclization of the γ-(Δ~1-cyclohexenyl)-butyric acid to Δ~(9∶10)α-octalone was carried out by the usual method of Darzens.

在氯化鋁的催化影響下以丁二酸酐作用於環已烯而製得γ-(Δ~1-環已烯基)-γ-丁酮酸。其他的Lewis酸如氯化鐵及氯化錫都經用作催化劑而進行試驗;但未得滿意的結果。將γ-(Δ~1-環己烯基)-γ-丁酮酸還原為γ-(Δ~1-環己烯基)丁酸時,Wolff-Kishner及黄鳴龍的方法都經過了試驗,但僅前法獲得成功。最後將广γ-(Δ~1-環己烯基)-丁酸環化而成Δ~(9∶10) -α-八氫萘酮則是以通常的Darzens法完成的。

Experiments are performed to use a brand of Chinese filter paper in paper chromatographic analysis. The paper used is the "fine" grade filter paper manufactured by the First Eastern Factory, Fou-Shun. It appears that the filter paper, after adequate treatment, may be used in paper chromatographic work. Treatment essentially consists of washing with dilute hydrochloric acid and distilled water and ascending with suitable solvents of the particular cation-groups. In this experiment, the solvents used for chromatographic analysis of aluminium, silver and arsenic groups were modified from that used by F. H. Burstall and others. The results are summarized as follows:Group I R_f: K 0.45, Na 0.56, Mg 0.71Group Ⅱ R_f: Ba 0.45, Sr 0.53, Ca 0.61Group Ⅲa R_f: Al 0.02, Zn 0.73Group Ⅲb R_f: Fe 0.99, Co 0.44, Mn 0.30, Ni 0.00Group Ⅳa R_f: Ag 0.16, Pb 0.00, Hg 0.80Group Ⅳb R_f: Pb 0.02, Cu 0.30, Bi 0.67, Cd 0.82, Hg 0.90Group V R_f: As 0.79, Sb 0.93, Sn 0.95Besides, we have found a number of common reagents which can be used to develop the cations on such kind of filter paper. After chromatographic separation, their sensitivity is determined. The R_f of both the ascending and descending processes has very close values. When temperature varies within 5°C, the R_f values change very little.

1.国产抚顺东一廠细号濾纸对无机阳离子層析的效果不低於进口滤纸。为了適應该纸的性質,铝族、银族、砷族所用溶剂曾略加修改。并找出该纸所含杂質较多,使用前须先用该组溶剂上昇一次,同时又可消除鬼斑(ghost spot)。 2.在此国产濾纸上较全面地整理了各分析组离子層析的条件,以便於未知物在此纸上进行系统層析及检验。并對層析後的離子进行了靈敏度的测定。 3.在国产纸上層析无机陽離子时,温度以及上昇法與下降法對R_f值之影响不大。
