Abstract

The pores of a solid carbon body, or at least the surface pores thereof, are filled by expelling the contents of the pores, filling the pores by immersing the body in a hardenable liquid mixture of furfural and an amine and heating the impregnated body at at least 100 DEG C. to harden the mixture within the pores. The pores may be evacuated by subjecting the body to subatmospheric pressure and the body may be under atmospheric or subatmospheric pressure when immersed in the liquid mixture. Alternatively the expulsion of the pore contents and the filling may be effected simultaneously by heating the liquid mixture, while the body is immersed therein, at the boil for a period insufficient to harden the mixture. The impregnated body should be heated to at least 200 DEG C. preferably 300 DEG C., and may be heated above the carbonization temperature of the hardened pore filling, e.g. at 1000 DEG C. Amines may be aliphatic, aralipathic, aromatic, or heterocyclic amines including aliphatic amines containing at least two primary amino groups or at least one amino group and at least one hydroxyl group, e.g. monoethanolamine, N-hydroxyethylethylene diamine, ethylene, propylene, or hexamethylene diamines, polyalkylene polyamines, aniline, p - phenylene diamine, piperidine, or benzylamine. The mixture may contain 30-60 per cent amine, but it is preferred to use a proportion of furfural greater than the amine.
