为了对制备乙醇胺铂(Ⅳ)的工艺进行优化,在铂浓度、氧化剂用量、氢氧化钠用量等单因素设计和实验结果的基础上,采用响应曲面法优化合成条件,建立预测乙醇胺铂(Ⅳ)产率的数学模型。结果表明,影响因子显著性顺序为:铂浓度>NaOH用量>氧化剂用量。当铂浓度为100 g·L~(-1),NaOH用量为2.25倍,氧化剂用量为10%时,预测乙醇胺铂(Ⅳ)的产率为89.26%。实验证明,该模型对乙醇胺铂(Ⅳ)制备条件的优化及产率的预测较为准确可靠。通过样品表征,验证了该化合物的结构式为(NH_3CH_2CH_2OH)_2Pt(OH)_6。
In order to optimize the preparation process of ethanolamine platinum (Ⅳ), the response surface methodology was used to optimize the synthesis conditions on the basis of the single factor design and experimental results of platinum concentration, oxidant dosage and sodium hydroxide dosage, Mathematical model of productivity. The results showed that the significant order of influencing factors was as follows: concentration of platinum> amount of NaOH> amount of oxidant. When the concentration of platinum was 100 g · L -1, the amount of NaOH was 2.25 and the amount of oxidant was 10%, the yield of ethanolamine platinum (Ⅳ) was predicted to be 89.26%. Experiments show that this model is more accurate and reliable for the optimization of the preparation conditions of ethanolamine platinum (Ⅳ) and the yield. The structure of the compound was confirmed by the sample characterization as (NH_3CH_2CH_2OH) _2Pt (OH) _6.
