Common_NamePyrocatechol
DescriptionGuaiacol may be obtained directly from beechwood tar, from pyrocatechin by methylation with potash and potassium methyl sulphate at 180, or from anisole by nitration, reduction of the ortho-nitroanisol to amino-anisol, which is then diazotized and boiled with water. It melts at 28 and boils at 250. It is employed in medicine as an expectorant. The dimethyl ether or veratrol is also used in medicine. Many other pyrocatechin derivatives have been suggested for therapeutic application. Guaiacol carbonate is known as duotal, the phosphate as phosphatol, the phosphite as guaiaco-phosphal; phosphotal is a mixture of the phosphites of creosote phenols. The valerianic ester of guaiacol is known as geosote, the henzoic as benzosol, the salicylic as guaiacolsalol, while the glycerin ether appears as guaiamar. Pyrocatechol, often known as catechol or benzene-1,2-diol, older name pyrocatechin, is a benzenediol, with formula C6H4(OH)2, first prepared in 1839 by H. Reinsch by distilling catechin (the juice of Mimosa catechu); it occurs free in kino and in beechwood tar; its sulfonic acid is present in the urine of the horse and man.
