Abstract
Resinous condensation products are prepared by reacting an aldehyde, such as formaldehyde, paraformaldehyde or hexamethylenetetramine with the product obtained by condensing in presence of a cationic condensing agent a phenol free of unsaturated hydrocarbon substituents with an alkyl ether of a phenol having a nuclear unsaturated hydrocarbon substituent. Suitable saturated phenols are phenol, cresol, xylenol, naphthols or anthranols. Polyhydric phenols are also suitable. Suitable unsaturated phenolethers are alkyl ethers of cashew nut shell liquid or of distillates or residues therefrom, or of isolates therefrom such as anacardic acid or cardol or cardanol, or ethers of marking nut shell liquid or of anacardol or urushiol. Other suitable ethers are anethole, eugenol, isoeugenol, safrole and iso-safrole. Ethers of phenols containing crotyl, allyl, methallyl, vinyl, propenyl, iso-propenyl, cyclohexene or other olefinic substituents may also be employed. Suitable condensing agents are sulphuric acid, phosphoric acid, zinc chloride, aluminium chloride, boron trifluoride, benzene sulphonic acid or hydrochloric acid. In examples: (1) phenol is condensed with the ethyl ether of o-allyl phenol in presence of sulphuric and acetic acid. The product was reacted with hexamethylene tetramine; (2) a mixture of cresols was condensed in presence of sulphuric acid with the ethyl ether of cashew nut shell liquid and the product was heated with hexamethylene tetramine. The products are useful as moulding powders or as binders in brake linings. They may be cured, ground and used as fillers for brake linings. Samples have been furnished under Sect. 2 (5) of (1) a product obtained by reacting formaldehyde with the condensation product of phenol with the ethyl ether of cardanol, and (2) the product obtained by reacting paraformaldehyde with a condensation product from phenol and the ethyl ether of cardanol. The Specification as open to inspection under Sect. 91, states that the products are soluble in vegetable oils such as linseed or chinawood. A product is prepared according to the invention in presence of phenol. Dissolved in alcohol it is said to be good for laminating paper cloth or wood or for coating metal. Glyoxal, trioxymethylene and furfuraldehyde are also mentioned. This subject-matter does not appear in the Specification as accepted.
