説明P-Anisic acid, also known as 4-Methoxybenzoic acid or draconic acid, is an organic acid that has a sweet flavor. It is one of the isomers of anisic acid, including m-anisic acid and o-anisic acid. The term "anisic acid" often refers to this form specifically. P-anisic acid is produced through the oxidation of p-cresyl-methyl ether.
使用4-Methoxybenzoic acid (p-Anisic acid) is used in oxidation and reduction of cytochrome c in solution through different self-assembled monolayers on gold electrodes using cyclic voltammetry. p-Anisic acid has antiseptic properties. It is also used as an intermediate in the preparation of more complex organic compounds.
一般的な説明4-Methoxybenzoic acid is the sole source of carbon and energy for growth in the cultures of Nocardia sp. DSM 1069. It is effective in clearing congestion in the lungs and the respiratory tracts in conditions like asthma or bronchitis.
調製方法
製造方法To obtain 4-Methoxybenzoic acid, the mole ratio of cobalt and manganese is modified and p-methoxy toluene is reacted with oxygen or an oxygen-containing gas in the presence of acetic acid. The following is the experimental procedure:1. Using n-hexyl bromide, tri (n-hexyl) amine, para-methoxy toluene with cobalt chloride hexahydrate in about 9h;2. By a catalytic oxidation process using p-methoxy toluene and propionic acid over a catalyst comprising of CoBr2.6H2O and MnBr2.4H2O with a reaction time of 20h;3. Through changing the mole ratio of cobalt and manganese, using p-methoxy toluene with oxygen or oxygen containing gas in the presence of acetic acid to obtain the product.
純化方法Crystallise p-anisic acid from EtOH, water, EtOH/water or toluene. The S-benzylisothiuronium salt has m 189o (from EtOH). [Beilstein 10 II 91, 10 III 280, 10 IV 346.]
