摘要

以尿素和甲醛为原料

在碱性水溶液中合成了二羟甲基脲

利用FTIR

1HNMR和元素分析对其结构进行了表征.同时以二羟甲基脲为原料

通过熔融缩聚制备了脲醛缩聚物

通过FTIR

1H NMR

1 3 C NMR和15N NMR对其结构进行了表征.实验结果表明:经二羟甲基脲熔融缩聚制备的长效脲醛缓释化肥

其可利用指数(AI)为98.6%

证明该法是合成长效脲醛肥料的有效途径.

Abstract

Dimethylolurea was synthesized from urea and formaldehyde in alkalescence and the compound was identified by FTIR

1 H NMR and elemental analysis.The condensation polymer of dimethylolurea was synthesized from dimethylolurea by melt polycondensation and identified by FTIR

1 H NMR

13 C NMR and 15 N NMR.The results show that the slow-release urea-formaldehyde fertilizer made from dimethlolurea by melt polycondensation has a high AI(98.6%)

so it indicates this method is very effective in the preparation of slow-release urea-formaldehyde fertilizer.
