(1) Tectoquinone, the volatile crystalline ingredient of the teak wood, which was isolated by R. Romanis in 1887, represents β-methyl-anthraquinone.(2) Tectoquinone, on oxidation, gives tectonic acid, which is identical with anthraquinone-β-carboxylic acid.(3) Tectoquinone, on reduction, gives a hydrocarbon ‘tectonene’, which, on examination, was proved to be β-methyl-anthracene.(4) Tectoquinone, on treatment with zinc and acetic anhydride, gives β-methyl-anthra-hydroquinone diacetate melting at 216–217°C., which is very easy to purify and thus may be used for the purpose of identifying tectoquinone.(5) β-Methyl-anthra-hydroquinone diacetate, on treatment with alcoholic potash and subsequent exposure to the air, regenerates tectoquinone of highest purity, melting at 176–177°C.
(1) Tectoquinone是由R. Romanis于1887年分离出的柚木的挥发性晶体成分,它代表了β-甲基蒽醌。(2) Tectoquinone在氧化时生成与蒽醌-β-羧酸相同的构造酸。(3) Tectoquinone在还原时生成一种烃“tectonene”,经检验证明其为β-甲基蒽。(4) Tectoquinone与锌和乙酸酐反应生成熔点为216-217°C的β-甲基蒽醌二乙酸酯,这种化合物非常容易纯化,因此可以用于识别tectoquinone。(5) β-甲基蒽醌二乙酸酯与酒精钾处理后,随后暴露于空气中,能够再生出纯度最高的tectoquinone,熔点为176-177°C。
