1, 2—Bis (P—bromobenzylamino) ethane (Ⅱa) and 1,2—bis (m—Iodobenzylamino) ethane (Ⅱb) may be prepared by condensation of the corresponding halo benzaldehyde with ethylenediamine and followed by catalytic hydrogenation of the Schiff's bases over Pto_2 in glacial acetic acid solutions: Both Ⅱa and Ⅱb may react in neutral mediam with aldehydes to form well—defined crystalline tetrahydro—imidazole (Ⅲ), which may be served as derivatives of identification for aldehydes: Under the same condition, however, Ⅱb may also...

1, 2—Bis (P—bromobenzylamino) ethane (Ⅱa) and 1,2—bis (m—Iodobenzylamino) ethane (Ⅱb) may be prepared by condensation of the corresponding halo benzaldehyde with ethylenediamine and followed by catalytic hydrogenation of the Schiff's bases over Pto_2 in glacial acetic acid solutions: Both Ⅱa and Ⅱb may react in neutral mediam with aldehydes to form well—defined crystalline tetrahydro—imidazole (Ⅲ), which may be served as derivatives of identification for aldehydes: Under the same condition, however, Ⅱb may also reach with methyl ketones, but Ⅱa does not. Thus Ⅱa is preferred as specific reagent for characterization of aldehydes rather than Ⅱb. At room temperature, on treatment with dilute mineral acid, (Ⅲ) hydrolyzed quanntitatively to the original aldehydes, which may be recovered by extraction with cther, (Ⅱa), therefore, may also be used as an effective separating reagent for aldehydes. The neutral equivalent weights of (Ⅲ) may be determined by non—aqueous titration with semi—micro manipulation. The results obtained will he served as supplemental data for identification purpose This method seemed to be a hopeful way for quantitaive analysis of aldehydes. The study on this aspect is carrying on in this laboratory and the result will be reported in the near future.

1.用1,2-二(对溴苄氨基)乙烷与二十余种醛类作用,得到有固定熔点的晶体衍生物,它们的熔点分布在85—210℃之间,产率为40—96%,这试剂与甲基酮类在相同条件下无反应,因此,它可作为鉴定醛类的专属试剂。 2.上述衍生物用稀盐酸在室溫处理,能发生水解,可以定量地收回原来的醛,因此这试剂又可作为分离醛类的试剂。 3.上述衍生物可以用非水滴定法半微量地测定其分子量可作为鉴定醛类的另一项参考数据。 4.1,2-二(间碘苄氨基)乙烷与醛类能生成晶体衍生物,但这试剂也与甲基酮在同样条件下发生反应,所以不适合作为鉴定醛类的专属试剂。

In the present paper, the following five systematic steps for microidentification of organic compounds have been studied: 1. Detection of elements: A rapid and simple micro-method was developed for the detection of fourteen important hetero-elements(N, F, Cl, Br, I, S, P, As, Sb, Hg, Si, Sn, B, Fe)in organic compounds. The sample having been broken down by Schoniger oxygen-flask combustion, the resulting ions were separated and detected by using Weisz ring oven technique. Several color reactions for the detection of nitrate, sulfate and halogen ions on ring oven have been modified to improve the selectivities as well as sensitivities. The detection limits for elements were 0.01 to 1μg in sample weighing 50—500 wg(cf Table 1, 3, 4, 5 in the Chinese text). 2. Determination of physical constants: Triphenyl silanol(m. p. 155.5℃, K=15)and triphenyl phosphine(m. p.79.5℃, K=12)have been proved to be suitable solvents in micro Rast cryscopic molecular weight determination for elemento-organic compounds. 3. Classification tests: The traditional classification by solubility has been modified for micro-analysis in two respects:(i)two new in. dicators were employed to classify the acids and bases instead of testing the solubilities in reaction solvents. Our indicators seemed to be more sensitive than those suggested by Davidson(cf. Table 8—10);(ii)Oxygen-containing compounds were detected by Ferrox test instead of testing solubility in conc. sulfuric acid. In order to increase the sensitivity of detection, the micro-technique of using ion-exchanger or silica gel grains as reaction media was employed. 4. Detection of functional groups: Based on the principle of ring-oven technique, a more simply constructed“Pinch-Clamp Line Oven”was designed. Some common organic functional groups(acid anhydrides, acid halides, alcohols, aldehydes, amines, amino acids, carbohydrates, carboxylic acids, esters, glycols, ketones, phenols)have been detected with this specific tool.(see Table 11). 5. Preparation of derivatives: The specific reagents for identifying aldehydes, 1,2-bis anilino ethane(DAE)and 1,2-bis(p-bromo benzyl amino)ethane(DBE)heve been studied. Owing to its higher molecular weight and the lower solubilities of its aldehyde derivatives, DBE seemed to be more suitable than DAE for the micro-iden-ti fication of water-insoluble aldehydes in organic mediums. Aldehyde derivatives prepared from the two reagents could be charact-erized not only by their sharp melting points(see Table 12)but also by their well-defined crystalline forms. Thirty-two photomic-rographs of these crystalline derivatives have been taken for this purpose(see fig 2—33). The neutral equivalent weights of DAE and DBE derivatives determined by non-aqueous titration will be added as further aid in identi-fication. A micro-manipulation for titration was developed.
