Abstract
The invention provides a method of conjugating double bonded drying oil so that a relatively low cost linseed oil, for example, can replace the more expensive, naturally conjugated tung oil which has been used heretofore. The conjugation is brought about by the use of ruthenium as a catalyst, with formic or a similar acid providing a synergistic augmentation of the reaction. The conjugated oil may have many uses, but a major object is to provide a way to enhance a phenolic resin adhesive used on wood and wood products.
