摘要
研究了固相研磨法、固相催化研磨法和熔融法三种实验条件下,甘氨酸与硫酸亚铁铵以物质的量之比2:1反应得到二价亚铁与甘氨酸的配合物.通过对配合物进行红外光谱表征和定量分析,得到二价亚铁配合物的组成为[Fe(Gly)2].最后,根据熔解-量热法的基本操作条件,设计了热化学循环,测量了反应物和产物的标准摩尔溶解焓,结合热化学原理,测定了甘氨酸亚铁的标准摩尔生成焓.
This topic mainly researches the reaction of glycine and ammonium ferrous sulphate at the ratio of the amount of 2：1 to get the complexes of bivalent ferrous and glycine through solid-phase grinding method, solid phase catalysis grinding method and melting method. Through IR characterization and quantitative analysis, we are sure that the composition of ferrous complexes is [Fe（Gly）2]. Finally, according to the basic operation conditions of Dissolve- Quantity hot method, we designed the thermal and chemical circulation, and measured the standards Moore of reactant and product, which is combined with hot dissolving enthalpy chemical principle; we estimate the standard Moore of ferrous glycinate.
