1.Five Schiff bases were prepared from piperonal and diamines by condensation reaction.

1.成新的双-胡椒醛缩二胺类席夫碱化物。

2.Cu furaldehyde-ethylene diamine Schiff base complex was synthesized with the yield of 63.

2.成了种席夫碱金属络物——呋喃甲醛乙二胺铜络物,收率为63。

3.According to the ethylene diamine moiety in the structure of some calcium antagonists,we designed and synthesized 5 unreported phenoxybenzamine derivatives.

3.利用酚苄明氯乙胺的活性，些钙拮抗剂含乙二胺的特征，设计成了5个酚苄明衍生物。

4.Two series of thermotropic liquid crystalline polyureas were synthesized by the copolymerization of benzidine (or o-tolidine),1,6-hexane diamine and 2,4-toluene diisocyanate.

4.为成新型热致液晶聚脲，以含液晶元的联苯二胺（或联邻甲苯胺）、1，6-己二胺、2，4-甲苯二异氰酸酯为原料进行成。

5.When the complex of anhydrous zinc acetate with 1,5-naphthalene diamine was formed, the anhydrous zinc acetate changed from a bidentate ligand to a unidentate ligand.

5.在无水乙酸锌与1,5-萘二胺形成配位络物的过程，无水乙酸锌的从双齿型转变成单齿型。

6.3, A chelating agent which forms an easily water-soluble metal chelated compound such as nitrilotriacetate (NTA) or ethylene diamine tetraacetate (EDTA) is incorporated in a detergent composition.

6.在洗衣粉掺入螯剂，例如次氮三乙酸酯（NTA）或者是乙二胺四乙酸酯（EDTA），这些螯剂易于形成水溶性的金属螯物。
