“…A number of papers have reported on the reaction products between tung oil and phenols, but they have reported little on the reaction between tung oil and phenols. [2][3][4][5][6][7][8][9][10][11][12][13][14][15][16] In this paper, more detailed discussion about the amount of 3methyl phenol reacted with tung oil, the bond position in 3-methyl phenol and so on are made from the results of IR, NMR, and HLC analyses.…”

SynopsisThe aromatic ring substitution reaction of 3-methyl phenol with tung oil under acidic conditions was carried out. The product was analyzed to find out if 3-methyl phenol was subjected to the ring substitution reaction with tung oil a t its conjugated double bonds. Up to two molecules of 3-methyl phenol were addition-reacted with the conjugated triene of one eleostearyl group of triglyceride of a-eleostearic acid which is the major component of tung oil. The 4-position of 3-methyl phenol was preferentially subjected to the cresol's ring Substitution. Therefore, up to 6 mol of 3-methyl phenol was added to 1 mol of t u g oil, most of which was bonded to 3-methyl phenol at its 4-position. When 3-methyl phenol was reacted with a relatively large amount of tung oil, the substitution reaction occurred at the 6-as well as 4-position of 3-methyl phenol to yield a tung oil dimer having 3-methyl phenol units in its molecule. The above results were confirmed by infrared (IR), nuclear magnetic resonance (NMR), and high-speed liquid chromatographic (HLC) analyses.
