Abstract

1,228,759. Clays. ENGLISH CLAYS LOVERING POCHIN & CO. Ltd. 7 Aug., 1968 [11 Aug., 1967], No. 37122/67. Heading C1A. A mineral silicate having a layer lattice structure is treated with a complexing agent to form an intercalation complex and the complex is bleached with an oxidizing bleaching agent. Complexing agents that may be used are: urea, benzidene, octylamine, formamide, acetamide, ammonium acetate, caesium and rubidium salts of acetic, propionic and cyanoacetic acids, alkali metal salts of amino acids. Bleaching agents that may be used are: H 2 0 2 ; an organic peroxy compound, e.g. peracetic acid or perbenzoic acid, chlorine chlorine water, chlorine dioxide, potassium permanganate, an alkali metal chlorite, permonosulphuric or perdisulphuric acid or an alkali metal or ammonium salt thereof; or a ' compound able to form H 2 O 2 on contact with water. When HgO a is used, the mixture of intercalation complex and bleaching agent is allowed to stand at an acid pH not greater than 4.5, for from 2 to 5 weeks at room temperature.
