This work was undertaken to invgate the application of nonaqueous titration to the determination of tablets of anti-malarial drugs, with the view of finding out a simple, rapid and accurate method of analysis. Eleven kinds of tablets have been determined and the results as compared with those by the official methods are satisfactory. With the elimination of tedious extractions and evaporation of the solvent, a method is proposed as follows: Dissolve the finely pulverized and accurately weighed sample of about 0.5 milliequivalent weight of 1N HCl, in a 100ml Erlenmeyer flask and digest on a water bath for 10 min. After cooling, the solution, made alkaline with 3ml of 6N NaOH, is cooled under tap water and extracted with 30ml of chloroform with vigorous shaking for 10 min. Add 1 gm of tragacanth powder, shake for 2 min. till the solution becomes clear (if it remains turbid, add one more gm of tragacanth powder and shake) and filter through absorbent cotton. Titrate 20 ml of the clear filtrate with acetous perchloric acid, using 1 drop of crystal violet solution as indicator, to the end point which is blue for colorless sample or green without red tint for yellow-colored sample. A blank is run.

Investigations have been made on the characteristics of the oscilloscopic polar-graphy of uranium(Ⅵ) in solutions of acetonitrile, acetone, methyl alcohol, ethyl alcohol or tetrahydrofurane with nitric acid as the supporting electrolyte. The influence of organic solvents and crown eth.ers on the properties of the oscilloscopic polargraphy of uranium was discussed. Uranium(Ⅵ) shows an excellent reversibly reductive wave in the medium composed of actonnitrile and nitric acid. Acetone, methyl alcohol or ethyl alcohol may be employed in place of acetonnitrile. The determination of uranium in nonaqueous solutions by the oscilloscopic polargraphic method is, therefore, of wide prospect of applicability.In the present work, the oscilloscopic polargraphic method for analysis of uranium in uranylcrown ether complex compounds has been established. In this method a sample is first dissolved in acetonitrile, an equal volume of 4N nitric acid is then added and the reductive current of uranium (Ⅵ) measured in a straightforward way. The method is characterized by its simplicity and rapidity. Determination of a couple of samples can be accomplished in 20 minutes, with an accuracy higher than 2%.

In the methanol solution of polymeric acid,the content of carboxyl groups hasbeen analy zed by the conductometric titration.While the aqueous solution ofsodium hydroxide was used as the titrant,the titration curve appeared to be quitedifferent from that of simple weak acid(e.g.CH_3.COOH),so that the end pointcould not be ascertained.In orded to overcome this difficulty,we have found twodifferent systems:1)by adding suitable amount of water,2)by adding suitableamount of simple salt(KC1)to the nonaqueous polyacid solution.The end pointcan then be determined from the conductometric titration curve in both systemsvery easily and accurately.The KCl-system method appears to be simplier.ThePhenolphthalcin-indicator end points in both systems are consistent with that ofthe conductometric titration method,but the reproducibility of the latter isbetter.In comparison together with the result of the viscosity titration,an explanationof the anomaly of the conductometric titration curve with pure methanol as thesolvent has been given.

用电导滴定法测定含羧基聚合物在甲醇溶液中的羧基含量时,若采用氢氧化纳水溶液为滴定剂,在滴定曲线上难以确定终点.为此,本文提出两种滴定体系:对具体样品选用适当量的混合溶含水剂;在聚酸溶液中加入中性盐(KCl),KCl 的当量浓度与被滴定物的羧基估计当量浓发相当.结合粘度滴定的结果,本文对电导滴定出现异常滴定曲线提出了初步解释.
