    摘要： Metal silicates of Groups II to IV of the periodic system are hydrophobized by treating an aqueous suspension of the silicate with an organohalosilane with intensive stirring at 15* to 70* C. The precipitate is then filtered, washed, dried and tempered at 200* to 500* C.

    摘要： Alkali ferrocyanides are prepared by converting calcium hexacyanoferrate (II) with an iron (II) salt to an iron (II) hexacyanoferrate (II), washing the complex with water until free of calcium ions and then reacting further with sodium, potassium or ammonium cyanide.

    摘要： Berlin blue is produced by converting (a) calcium ferrocyanide, sodium ferrocyanide or magnesium ferrocyanide with (b) an iron II salt at a pH below 7 to an acidic iron II salt of ferrocyanic acid FeH2(Fe(CN)6). The calcium or sodium ions can be washed out of the precipitate of the ferrocyanic salt. The precipitate is treated with (c) an inorganic or organic potassium salt to form Berlin white and then oxidized to Berlin blue. Alternatively, (a), (b) and (c) can be reacted together at a temperature of 20* to 60*C. to form Berlin white directly.
