  • Patent number: 5226956
    Abstract: A paint or varnish composition is described which comprises a medium, such as an alkyd resin, and an anticorrosion agent which is environmentally non-hazardous and soluble or adapted to be soluble in the medium. The composition is suitable for application to a metal substrate and the anticorrosion agent is selected so as to enable a dry paint or varnish film to be obtained on the metal substrate, preferably within 24 hours from the time of application.

  • Patent number: 4940572
    Abstract: A process is disclosed for the production of micaceous iron oxide using metallic iron, for example scrap iron, as a feed stock for the preparation of an iron chloride and the resulting iron chloride is oxidized at an elevated temperature in the presence of a salt of an alkali metal or alkaline earth metal, preferably sodium chloride. A reaction may be effected in a packed tower reactor comprising a refractory tube 7 containing an inert packing material e.g. aluminosilcate ceramic balls. The reaction charge including packing material, metallic iron and the salt is introduced via hopper 13. A tube 7 is externally heated by electrical resistance elements 10 and chlorine and an oxidizing gas are introduced at inlet 8 and the off-gas removed at outlet 9. The micaceous iron reaction product is obtained as a coating on the inert packing material. Micaceous iron oxide is used as a pigment for the formulation of metal protective paints.

  • Patent number: 4269816
    Abstract: The invention relates to a process for the preparation of anhydrous magnesium chloride from magnesium carbonate preferably magnesium carbonate ores such as magnesite. The process comprises reacting solid magnesium carbonate pieces preferably screened ore in a packed bed reactor comprising the magnesium carbonate pieces with gaseous chlorine in the presence of carbon monoxide at a temperature above the melting point of magnesium chloride and below 1200.degree. C. The off-gas predominantly carbon dioxide is withdrawn from above the packed bed and molten anhydrous magnesium chloride is withdrawn from below the packed bed. The invention provides a process having low energy requirements which can be applied industrially on a continuous basis using simple apparatus.

  • Patent number: 4259298
    Abstract: The invention relates to a method of recovering the chlorine values from iron chloride obtained from the chlorination of an aluminous material containing iron oxide, such as bauxite. The method involves partially dechlorinating ferric chloride in the presence of a reducing agent to form products comprising ferrous chloride and a chloride compound derived from the reducing agent and oxidizing ferrous chloride at a temperature of about 300.degree. C. to 1200.degree. C. to form products comprising ferric chloride and ferric oxide. The ferric chloride is recycled and the chlorine values are recovered as the chloride of the reducing agent which is suitable for recycle to the aluminous chlorination stage or has other industrial utility.

    Assignee: Mineral Process Licensing Corp. B.V.
    Inventors: John H. W. Turner, Charles E. E. Shackleton
  • Patent number: 4140746
    Abstract: The invention relates to the recovery of chlorine values from iron chloride by-produced from the chlorination of a titaniferous material containing more than 5% by weight iron oxide, and particularly from the carbo-chlorination of ilmenite, which, for example, can be the first stage in the so-called chloride route to form titanium dioxide pigment.The iron chloride which may be ferric chloride or ferrous chloride is subjected to a combination of reduction and oxidation reactions. In the reduction reaction, ferric chloride is dechlorinated to ferrous chloride by a reducing agent suitable for producing a chloride compound for recycle to the chlorination process or for sale and in the oxidation reaction ferrous chloride is oxidized to ferric oxide and ferric chloride, the ferric chloride being recycled to the reduction reaction.
