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.

The following chart shows the solubility of various ionic compounds in water at 1 atm pressure and room temperature (approx. 25 °C, 298.15 K). "Soluble" means the ionic compound doesn't precipitate, while "slightly soluble" and "insoluble" mean that a solid will precipitate; "slightly soluble" compounds like calcium sulfate may require heat to precipitate.
The tables below provides information on the variation of solubility of different substances (mostly inorganic compounds) in water with temperature, at one atmosphere pressure. Units of solubility are given in grams of substance per 100 millilitres of water (g/100 ml), unless shown otherwise. The substances are listed in alphabetical order.
The residue remaining in the autoclave vessel is a dark, syrupy mass called creosote, which is composed mainly of phenolic acid and cresylic acid. The original composition of creolin is a creosote tar oil, caustic soda, soaps, and very little water. It is of low technology and a very powerful disinfectant. [1]
In these systems, copper is ground into micro sized particles and suspended in water rather than dissolved, as is the case with other copper products such as ACQ and copper azole. There are two particulate copper systems in production. One system uses a quat biocide system (known as MCQ) and is a derivative of ACQ. The other uses an azole ...
To increase the volume of creosote available for wood treatment, Southern Pacific used creosote extenders in the site's treatment process. [18] Concerns arose when it was revealed [17] that some of these extenders were sourced from what are now Houston-area Superfund sites––including Brio Refining, Dixie Oil Processors, and Motco––bringing the extender's safety and toxicity into ...
A dense non-aqueous phase liquid or DNAPL is a denser-than-water NAPL, i.e. a liquid that is both denser than water and is immiscible in or does not dissolve in water. [1]The term DNAPL is used primarily by environmental engineers and hydrogeologists to describe contaminants in groundwater, surface water and sediments.
L. tridentata in Anza-Borrego Desert State Park. Larrea tridentata is a prominent species in the Mojave, Sonoran, and Chihuahuan Deserts of western North America, and its range includes those and other regions in portions of southeastern California, Arizona, southern Nevada, southwestern Utah, New Mexico, and Texas in the United States, and Chihuahua, Sonora, Coahuila, Nuevo León, Zacatecas ...
