Bis (P—bromobenzylamino) ethane and 1,2—bis (m—Iodobenzylamino) ethane 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, which may be served as derivatives of identification for aldehydes: Under the same condition, however,Ⅱb may ...

用1，2-二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。
