    The term creosote has a broad range of definitions depending on the origin of the coal tar oil and end use of the material. With respect to wood preservatives the United States Environmental Protection Agency (EPA) considers the term creosote to mean that it is a pesticide for use as a wood preservative meeting the American Wood Protection Association (AWPA) Standards P1/P13 and P2. Exposure to creosotes, coal tar, coal tar pitch, or coal tar pitch volatiles may be harmful to your health. Reports describing poisoning in workers exposed to coal tar creosote, or in people who accidentally or intentionally ate coal tar creosote prove that these chemicals can be harmful.5/5(2). Other creosotes include wood-tar, water-gas-tar, and oil -tar. • They have wood-preserving properties when of good quality and properly used. Coal tar alone is not a good preserver. • It is not very poisonous to fungi and it does not penetrate wood very well.

At least 75% of the coal tar creosote mixture is polycyclic aromatic hydrocarbons (PAHs). Unlike the coal tars and coal tar creosotes, coal tar pitch is a residue produced during the distillation of coal tar. This was ABSORPTION AND PENETRATION OF COAL TAR AND CREOSOTE.

11 probably due, as noted in the case of the penetrance Coal-tar and water-gas tar creosotes book, to the character of the carbon mat which formed when this tar was used.

Blocks treated with the mixtures containing varying amounts of free carbon were found to be fairly well penetrated. The present paper describes the study of the use of a water-reducing agent developed from another source, a coal tar waste commonly known as coal tar creosote.

These creosotes contain mixtures of naphthalene, anthracene, phenols, creosols and dimethyl naphthalene etc. The composition varies with the method of treat- ment for coal tar : S.K.

Agarwal, Irshad Masood. The authors recommend that a high-residue coal tar creosote solution specification be introduced as there is more than enough data to support its efficacy and superior properties as a long-term wood preservative.

INTRODUCTION Studies in South Africa on the efficacy of creosotes and coal tar cresosote solutions started prior to Heavy Oil.

The name heavy oil can often be misleading as it has also been Coal-tar and water-gas tar creosotes book in reference to (i) fuel oil that contains residuum leftover from distillation, that is, heavy fuel oil or residual fuel oil, (ii) coal tar creosote, or (iii) viscous crude oil.

The subject of compound classes in coal tar and creosote was discussed in general terms by McNeil (33). In coal tar, well over individual compounds have been identified, but the components in creosote belong to a relatively small number of chemical classes.

One of these, the polynuclear aromatic. Wood creosote, coal tar creosote, coal tar, coal tar pitch, and coal tar pitch volatiles differ from each other with respect to their composition.

Wood creosotes are derived from beechwood (Fagus, referred to herein as beechwood creosote) and the resin from leaves of the creosote bush (Larrea, referred to herein as creosote bush resin).File Size: 2MB.

Coal Tar Creosotes are distillation products of coal tar widely used for preserving wood. Creosotes pose a health risk due to carcinogenicity, and are banned from commercial use in many countries.

The European Union banned the commercial sale of creosotes in Creosote volatiles are complex, consisting of almost different compounds. However, creosote abuse by vapour Cited by: 4.

Coal tar and coal tar pitch share many of the polycyclic aromatic hydrocarbons (PAHs) components of coal tar creosote. For the coal tar derivatives, the composition of the mixture varies from batch to batch depending on the coking process used.

Creosote consists primarily of PAHs and, therefore. Coal-tar creosote contains phenols, cresols, and higher phenoloid bodies, also naphthalene and other solid hydrocarbons, as well as pyridin and other bodies of basic character. Creosotes vary in composition, and owe their germicidal properties to the phenol and cresols which they contain.

to be contaminated by coal tar. • The coal tar was suspected to have come from a local former manufactured gas plant which operated between and the ’s with two different production processes used during this time (Carburetted Water Gas then Oil-Gas).

• The waste was suspected to have been dumped in the early ’ Size: 1MB. The coal-tar variety, having stronger and more toxic properties, has chiefly been used as a preservative for wood; coal-tar creosote was also formerly used. Coal is a black or brown, solid, combustible mineral formed by the alteration of prehistoric plant life by bacterial decomposition, with subsequent chemical changes caused by temperature and pressure.

These processes result in a range of carbonaceous materials, the first of which is peat and the last of which is graphite (pure carbon). The coals lie between these two extremes.

Description Derivation of water-gas-tar creosote. Source Adapted from source, p Price, Overton W.; Kellogg, R.S.; Cox, W.T. Forests of the United States Author: Brian Shapiro. General Information. Coal tar is produced as a byproduct when coal is carbonized to make coke or gas.

When distilled, coal tar produces creosotes as a product and coal-tar pitch as a residue. [] Coal tars are viscous and slightly soluble in water, while coal-tar pitches can be semi-solid to solid. [] Coal tars and coal-tar pitches are complex mixtures containing over identified substances.

This concentration (12 g L À1) represents that of most real NAPLs, e.g., coal tar and creosotes (Eberhardt ; Mahjoub et al. ; Nelson et al. ;Tiruta-Barna et al. The single. (ERNS), coal tar is one of the most commonly spilled petroleum products the U.S []. Coal tar itself may also be subjected to distillation, a process that separates groups of the components of coal tar from groups of others [].

In commerce, creosote is a coal-tar distillate, a complex mixture of organic compounds, largely hydrocarbons. It is commonly used as a wood preservative. The creosote distilled from wood tar is a. Opaque, viscous tars derived from the carbonization of fossile carbon feedstocks, such coal tars and creosote, are long-term sources of groundwater contamination, predominantly with poly- and heterocyclic aromatic hydrocarbons (PAH).

Semigelatinous interfacial films, which may influence the fluid mechanic and mass transfer properties of coal tar in porous media, have been observed to form in coal tar−water systems when coal tars are aged in water under quiescent conditions for a few days.

In commerce, creosote is a coal-tar distillate, a complex mixture of organic compounds, largely hydrocarbons. It is commonly used as a wood preservative. The creosote distilled from wood tar is a mixture of phenolic compounds; it once was.

Creosote oils. The term creosote has a broad range of definitions depending on the origin of the coal tar oil and end use of the material.

With respect to wood preservatives, the United States Environmental Protection Agency (EPA) considers the term creosote to mean a pesticide for use as a wood preservative meeting the American Wood Protection Association (AWPA) Standards P1/P13 and P2.

Creosote is the portion of chemical products obtained by the distillation of a tar that remains heavier than water, notably useful for its anti-septic and preservative properties. It is produced in some quantities from the burning of wood and coal in blast furnaces and fireplaces; commonly found inside chimney flues when the wood or coal burns incompletely, producing soot and tarry smoke, and.

The recovery of coal tar or creosote, which are dense nonaqueous phase liquids (DNAPLs), from the subsurface has been used as a means of site remediation at several former manufactured-gas plant. the treatment of poles (4). There is also the possibility of mixing water-gas tar, wood-tar creosotes, and oil-tar creosote with coal-tar creosote.

Oil preservatives and their respective merits will be discussed later but in using them as diluents or blending agents with coal-tar creosote it is. Creosote is the portion of chemical products obtained by the distillation of a tar that remains heavier than water, notably useful for its anti-septic and preservative properties.

Coal tar and many of its constituents have been well characterized as oncogens in animal studies. However, because of the complexity of coal tar/creosotes, available studies are not adequate for quan- titative risk assessment.
