摘要
对使用二甲基海因与次氯酸钠合成1.3-二氯-5,5-二甲基海因(DCDMH)的反应条件进行了探讨.在二氧化硅水性分散液中可直接合成SiO2/DCDMH抗菌性无机/有机复合微粒子,并分析了该复合微粒子的多相结构与粒径分布.使用该复合微粒子能调制出稳定的SiO2/DCDMH水系分散液.
The reaction condition of dimethylhydantoin (DMH) and NaClO was investigated to synthesize 1,3- dichloro- 5, 5-dimethylhydantoin(DCDMH). Silica/DCDMH inorganic/organic composite particles were directly prepared in an aqueous suspension of silica. The polyphase structure of the composite particles and the particle size distribution were analyzed. The stable aqueous suspension of DCDMH can be prepared using the composite particles.
