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

1.成新的双-胡椒醛缩二类席夫碱化。

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

2.成了一种席夫碱金属——呋喃甲醛乙二铜,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.利用酚苄明中氯乙的活性，一些钙拮抗剂含乙二的特征，设计成了5个酚苄明衍生。

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（或联邻甲苯）、1，6-己二、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-萘二形成配位的过程中，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.在洗衣粉中掺入螯剂，例如次氮三乙酸酯（NTA）或者是乙二四乙酸酯（EDTA），这些螯剂易于形成水溶性的金属螯。
