Abstract

17,731. Plauson, H. Aug. 1. Carbon.-Pure finely-divided carbon is obtained from coal or wood charcoal by grinding it to a very fine powder, purifying by treatment first with sulphuric acid or a mixture of sulphuric and hydrochloric acid, washing with water, treating with nitric acid, again washing, treating with hydrofluoric acid, and again washing, traces of acid, if desired, being finally removed by means of alkali; the product is then brought into colloidal solution, preferably in water, by known methods, for example by means of tannin, by trituration at high speed or under great pressure, as described in Specification 17,729/13, [Class 50, Fuel, Manufacture of], or by the electric current; natural colloids such as gelatine, casein, indiarubber, albumens, &c. may be added to accelerate the process. The colloidal solution is allowed to settle and poured off, the residue being again treated as before; the carbon is then precipitated from the solution, for example by addition of acid or other electrolyte, and dried. It may further be heated in an atmosphere of hydrogen or nitrogen or in vacuo to carbonize any hydrocarbon present. The product is suitable for colouring purposes. Specification 7776/07 also is referred to.
