Abstract

The melting point of a resin obtained by condensation of an unsubstituted or hydrocarbon substituted aromatic hydrocarbon with an aldehyde is increased by heating with an acid-reacting hardening catalyst at a temperature above 140 DEG C., e.g. from 140 DEG to 200 DEG C., with subsequent stabilization of the resin by elimination of acidity. Resins specified are the condensation products of formaldehyde and naphthalene, xylene, naphtha fractions and methyl naphthalenes. Catalysts specified are sulphuric acid, phosphoric acid, ferric chloride, aluminium chloride, p-toluene sulphonic acid and p-toluene sulphochloride. Solvents such as toluene may be used. The acidity may be removed by neutralization, e.g. with alkali and alkaline earth metal carbonates, hydroxides and oxides, such as Na2CO3, CaCO3 and CaO, gaseous ammonia, ammonium carbonate, and organic bases, e.g. pyridine and quinoline and their derivatives. In the case of volatile catalysts, e.g. p-toluene sulphonic acid, the acidity may be removed by passing steam into the molten hardened resin. In example (1) a toluene solution of a naphthalene-formaldehyde resin is heated until free from water, p-toluene sulphonic acid is then added and the mixture heated, steam being finally admitted to remove the volatile catalyst. Further examples are given (2-5) showing how the acid concentration and/or time affects the degree of hardening and (6-8) showing comparatively how stabilization proceeds. Specification 633,923 is referred to.
