Description
A brownish oil with a phenolic odor obtained from the distillation of coal tar. Creosote contains cresol and other phenolic compounds with approximately 12 to 14% anthracene. Prior to World War I, anthraquinone dyestuffs were prepared from the anthracene in creosote. Creosote has also been used as an insecticide, fungicide, biocide, and disinfectant. It is a common wood preservative for railroad ties, telephone poles, marine pilings, and shingles.
