Creosote Chemical Properties,Uses,Production
Occurrence
Fagus species.
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
General Description
Colorless to yellowish oily liquid with a smoky odor and caustic burning taste.
Air & Water Reactions
May be sensitive to exposure to air. Slightly soluble in water.
Reactivity Profile
Phenols, such as CREOSOTE, do not behave as organic alcohols, as one might guess from the presence of a hydroxyl (-OH) group in their structure. Instead, they react as weak organic acids. Phenols and cresols are much weaker as acids than common carboxylic acids (phenol has Ka = 1.3 x 10^[-10]). These materials are incompatible with strong reducing substances such as hydrides, nitrides, alkali metals, and sulfides. Flammable gas (H2) is often generated, and the heat of the reaction may ignite the gas. Heat is also generated by the acid-base reaction between phenols and bases. Such heating may initiate polymerization of the organic compound. Phenols are sulfonated very readily (for example, by concentrated sulfuric acid at room temperature). The reactions generate heat. Phenols are also nitrated very rapidly, even by dilute nitric acid. CREOSOTE is incompatible with acacia, albumin, oxidizers and cupric, ferric, gold and silver salts.
Carcinogenicity
The carcinogenicity of creosote oils has been studied quite thoroughly using mice. Studies indicate that coal tar creosote and several of its fractions can be carcinogenic when applied to the skin of mice and rabbits. Dermally applied coal tar creosote can also act as a tumor-initiating agent when applied prior to croton oil treatment.
Hazard
In aquatic sediments, several reactions can transform the chemicals released by the creosote preservatives into more dangerous chemicals. Most creosote preservative compounds have hazards associated with them before they are transformed. Cresol (m-, p-, and o-), phenol, guaiacol, and xylenol (1,3,4- and 1,3,5-) all are acute aquatic hazards prior to going through chemical reactions with the sediments. Alkylation reactions allows for the compounds to transition into more toxic compounds with the addition of R-groups to the major compounds found in creosote preservatives. Compounds formed through alkylation include: 3,4-dimethylphenol, 2,3-dimethylphenol, and 2,5-dimethylphenol, which are all listed as acute environmental hazards.
