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.

Surface coating compositions

The invention provides metal-containing organic compositions for use as additives to surface coating compositions comprising:

Coating compositions are disclosed comprising a conventional paint medium and an aluminium compound such as aluminium alkoxide which is stabilized by a volatile base, preferably an amine, together with added water. The coating compositions remain stable on prolonged storage.

Oxo-aluminum complexes prepared by reacting a substituted aluminum alkoxide with a molar deficiency of water or carboxylic acid. The complexes are useful in surface coating compositions based on synthetic resins such as alkyd resins.

Oxo-aluminum complexes

Fungicidal compositions comprising at least one organometallic compound of aluminum and/or boron, at least one divalent metal and at least one carboxylic acid group. The compositions are useful in preserving timber.

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 C. The off-gas predominantly carbon dioxide is withdrawn from above the packed bed and molten anhydrous magnesium chloride is withdrawn from below the packed bed.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.

Preparation of anhydrous magnesium chloride

Method for preparing storage-stable air-drying compositions containing a combination of an aluminum alkoxide with a labile monofunctional reactant such as an alkanol, alkoxyalkanol, keto ester, water, hydrogen peroxide, organic hydroperoxide or mixtures thereof.

Method for preparing aluminum-based air drying compositions

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.

Recovery of chlorine values from iron chloride by-product in

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. By this method the chlorine values are recovered from by-product iron chloride by a route which avoids the difficult reaction between ferric chloride and oxygen to produce chlorine and ferric oxide.
