Abstract

The initial oily condensation product obtained by heating phenol with formaldehyde in the presence of sodium sulphite is mixed with a compound containing the CH2OH or CH.OH group and the mixture heated; the liquid product obtained may be converted into a hard infusible product by heating without pressure, or may be mixed with mineral fillers (clay, talc, mica &c.), moulded, and heated to give products suitable for electric insulation or building purposes, or the liquid product dissolved in an organic solvent may be used for coating or impregnating paper or paper board which is then hot-pressed and heated. Suitable hydroxy compounds are oxyfatty acids such as glycollic, lactic, malic, tartaric, or citric acid, alcohols, such as glycerol, butyl, amyl, ceryl, cetyl, or myricyl alcohol or cholesterol, or glucose, levulose, mannose, maltose, mannite, cane sugar, &c. Reference has been directed by the Comptroller to Specifications 27096/08, 129,993, 148,264, and 179,586.
