本文研究了室温时K~3Fe(CN)~6,K~4Fe(CN)~6在酸碱条件下发生的固相配位化学反应。结果表明:K~3Fe(CN)~6与NaBH~4固相混合物室温下不反应,但加入固体氢氧化钠后,K~3Fe(CN)~6与NaBH~4的固相氧化还原反应在室温下很容易进行。K~4Fe(CN)~6与K~2S~2O~8的固相氧化还原反应在室温下能顺利进行,但当固体KOH存在时,反应明显受到抑制。K~3Fe(CN)~6与K~2C~2O~4.H~2O室温下无反应,但与H~2C~2O~4.2H~2O在室温时即发生固相取代反应。

Solid state reactions of potassium hexacyanoferrate(III) and potassium hexacyanoferrate(II) at room temperature were studied by IR and Mossbauer spectroscopy. The results show that the reaction of potassium hexacyanoferrate(III) and sodium borohydride takes place easily if solid sodium or potassium hydroxide is added. The solid state redox reaction of potassium hexacyanoferrate(II) and potassium peroxydisulfate, which takes place easily at room temperature, is restrained by solid potassium hydroxide. No solid state redox reaction occurs between oxalic acid dihydrate and potassium hexacyanoferrate(III), but a solid state substitution reaction takes place at room temperature.

Key words: SOLID PHASES, SOLID PHASE REACTION, SODIUM HYDROXIDE
