Novikova, E. N. published the artcileEffect of the inhibitors on the formation of peroxides in α-pinene, Recommanded Product: 3,3-Bis(4-hydroxynaphthalen-1-yl)isobenzofuran-1(3H)-one, the publication is Vestsi Akademii Navuk BSSR, Seryya Fizika-Tekhnichnykh Navuk (1957), 47-55, database is CAplus.
To a 25 mL. glass tube was added 4 mL. freshly distilled α-pinene (I), d20 0.8573, n20D 1.4665, b. 155-6°, containing 4 m mol inhibitor/100 mL. I, and the tube placed in an oil bath at 110° for air oxidation during 2 h. The amount of peroxides (II) formed was then determined iodometrically and calculated as ml. 0.1N hyposulfite solution/l. oxidized I. Secondary aromatic amines: dinaphthylphenylenediamine, p-H2NC6H4NHPh, 2,4 – (H2N)2C6H3NHPh, 1,4 – diphenylenediamine, and p-HOC6H4NHPh caused total inhibition of the formation of II. Other equally effective inhibitors were p-hydroxyphenyl-β-naphthylamine, ο-, and p-aminophenol. The following aromatic compounds showed a much smaller inhibitory effect (in the decreasing order of the inhibitory efficiency): α-naphthol, phenyl-α-naphthylamine, nitrosodimethylamine, dihydroxynaphthalene, α-naphtholphthalein, hydroxyquinoline, phenyl-β-naphthylamine (III), and “aldol-α-naphthylamine” (titration values 1.5-10.1 mL. vs. 51.2-57.8 mL. for the controls), and hydroquinone (IV), pyrocatechol, pyrogallol, β-naphthol, β-naphthylamine, dianisidine, α-naphthylamine, phloroglucinol, resorcinol, Azatol A, p-toluidine, p-anisidine, nitroresorcinol, orcinol, m-tolylenediamine, ο-anthranilic acid, m-anthranilic acid, m-aminophenol, naphthalene, benzidine, ο-tolidine, hydroxyquinoline, and biphenyl (titration values from 11.8 to 50.4 mL.). Primary amines showed the lower inhibition. Naphthols were more effective than naphthylamines. ο- and p-Isomers of phenols and aminophenols inhibited formation of II more than did m-isomers. In another experiment, conducted on I and dipentene (fraction of turpentine, d20 0.8486, n20D 1.474, b. 174-5°), by using a dry O oxidation in a semivacuum at 80° 4 h., it was shown that the inhibitors are equally effective against formation of I in dry O as in the air. Addition of 0.005% Mn (as Mn stearate) to I did not increase the inhibitory effects of III and IV as found by the determinations of II and the O absorption by I. Triphenylphosphine and IV were found to be strong inhibitors against oxidation of terpenes. The inhibitory effects of the aromatic compounds against formation of II in I is discussed in the light of the chem. and structural nature of the inhibitors.
