Ethyl Ethylphenol

Chemically, wood tar is a complex mixture that contains at least 200 individual compounds, among which the foUowing have been isolated (1) 2-methoxyphenol, 2-methoxy-4-ethylphenol, 5-meth5i-2-methoxyphenol, 2,6-x5ienol, butyric acid, crotonic acid, 1-hydroxy-2-propanone, butyrolactone, 2-methyl-3-hydroxy-4JT-pyran-4-one, 2-methyl-2-propenal, methyl ethyl ketone, methyl isopropyl ketone, methyl furyl ketone, and 2-hydroxy-3-methyl-2-cyclopenten-l-one. 

Another elastomer to find use is the substitution product of phenol and -ethylphenol along with an aHylic monomer to provide cross-link sites (5). This is trademarked EYPEL-A elastomer [66805-77-4] by Ethyl Corp., and designated PZ by ASTM. The substitution ratio is roughly 52 mol % phenol, 43% j )-ethylphenol, and 5% aHylic substituent.

Recently, AEDA and SHA-0 yielded 41 and 45 odor active compounds for Scheurebe and Gewurztraminer wines, respectively (P). Ethyl 2-methylbutyrate, ethyl isobutyrate, 2-phenylethanol, 3-methylbutanol, 3-hydroxy-4,5-dimethyl-2(5H)-furanone, 3-ethylphenol and one unknown compound, named wine lactone, showed high flavor dilution (FD)- factors (Table I) in Gewurztraminer and Scheurebe wines. 4-Mercapto-4-methylpentan-2-one belongs to the most potent odorants only in the variety Scheurebe whereas cis-rose oxide was perceived only in Gewurztraminer (Table I). 4-Mercapto-4-methylpentan-2-one was identified for the first time in Sauvignon blanc wines (JO). The unknown compound with coconut, woody and sweet odor quality, which has not yet been detected in wine or a food, was identified as 3a,4,5,7a-tetrahydro-3,6-dimethylbenzofuran-2(3H)-one (wine lactone) (JJ).

Attempts to prepare 2(2-hydroxy-3-vinylphenyl)2H-benzotriazole or 2(2-hydroxy-4-vinylphenyl)2H-benzotriazole failed. When 3-ethyl-phenol or 4-ethylphenol were allowed to condense with o-nitrobenzene-diazonium salts, the condensation did not occur in the 2 position but rather in the 4 position. As a consequence, after ring closure, bro-mination and debydrobromination, 2(4-hydroxy-2-vinylphenyl)2H-benzo-triazole (4-H2V) and 2(4-hydr oxy-3 - vinylphenyl) 2H-b enzotr iaz ole (4H3V) were obtained (30) instead of the desired 2H4V and 2H3V.

The eneynone, 3-ethyl-5-oxo-oct-3-ene-6-yne in toluene solution upon heating with collidine 4-toluenesulphonate at 250°C, formed 3,4-dimethyl- 5-ethylphenol in 82% yield (ref.58). Although strictly this synthesis is relevant to the preparation of alkylphenols, it is conceivable that the parent Cg enynone, or a derivative,could be used for phenol itself.
