CREOSOTE Usage And Synthesis
Chemical Properties The nuts of the Fagus may be eaten raw or roasted. The seeds are often a source of edible oil and the leaves are used as a potherb. Beechwood creosote contains a mixture of phenols (chiefly guaiacol, creosol and p-cresol). It has a characteristic smoky odor with caustic, burning taste.
Occurrence Fagus species.
Uses Coal tar creosote has been used as a wood preservative pesticide in the United States since the late 1890s. This accounts for more than 97% of coal tar creosote production (383). Coal tar creosote prevents animal and plant growth on concrete marine pilings and is a component of roofing pitch.. Other uses include animal and bird repellent, insecticide, animal dip, fungicide, and pharmaceutical applications. Beechwood creosote has, in the past, been used for medicinal purposes. It is rarely used in the United States for medical purposes today.
Production Methods Wood creosote is obtained from wood tars, from beech and the resin from leaves of the creosote bush, and by distillation and is composed mainly of phenols, xylenols, guaiacol, and creosol. Coal tar creosote is produced by high-temperature carbonization and distillation of bituminous coal. Coal tar creosote contains liquid and solid aromatic hydrocarbons, tar acids, and tar base.At least 75%of the coal tar creosote mixture is polyaromatic hydrocarbons. Purification of the crude preparation is accomplished by distillation and extraction from suitable oils.
Preparation Starting materials are the heavy oils from wood tar; the material first is treated with NaOH to precipitate all saponifiable oils and subsequently with H2SO4; the raw creosote finally is purified by repeated fractional distillation
