Abstract
A material for dental and other purposes is prepared by first condensing phenol or a derivative with trioxymethylene or other solid body capable of liberating formaldehyde in the presence of a little alkali to yield an initial condensation product; then incorporating a body such as phosphoric anhydride to absorb the water of a later addition; next adding a sulphur-containing salt, such as sodium or potassium bisulphite, for the purpose of inhibiting oxidation; and finally hardening by means of an aqueous solution of an acid, particularly hypophosphorous acid, but also sulphuric acid or hydrochloric acid, or by means of a mixture of fuming sulphuric acid with crystalline acetic acid. The acid treatment may be dispensed with when an acid anhydride is the water-absorbent added; amyl acetate or zinc sulphide may be added to the initial condensation product to give a light colour.
