Abstract
A constituent of a rustproofing material consists of a liquid produced by nitriting an alkyl derivative of a cyclic alcohol by means of an acid and an inorganic nitrite and, after the reaction is complete, adding a solvent for the organic nitrite and filtering. For example, 2-methylcyclohexanol is mixed with sodium nitrite and water and to the mixture, which is agitated vigorously, aqueous sulphuric acid is added and the resultant liquid cooled continuously until the reaction is complete. Methylated spirit is then added and the liquid is filtered.ALSO:A material for rustproofing metals, e.g. for browning gun barrels and gun parts, includes a liquid produced by nitriting an alkyl derivative of a cyclic alcohol by means of an acid and an inorganic nitrite and, after the reaction is complete, adding a solvent for the organic nitrite and filtering. The rustproofing material may consist of about 3 per cent of the liquid so formed together with water and one or more metallic salts. In an example 2-methylcyclohexanol is mixed with sodium nitrite and water and to the mixture, which is agitated vigorously, a mixture of 1 part of pure sulphuric acid and 2 parts of water is added, the resultant liquid being cooled continuously until the reaction is complete. Methylated spirit is then added and the liquid is filtered. The filtrate may be mixed with a saturated solution of ferrous sulphate, a solution of antimony chloride, copper sulphate, and water to form a rustproofing material. The steel &c. to be rustproofed is cleaned and polished with lime water before the material is applied.
