Jatropha curcas is a species of flowering plant in the spurge family, Euphorbiaceae, that is native to the American tropics, most likely Mexico and Central America. [2] It is originally native to the tropical areas of the Americas from Mexico to Argentina, and has been spread throughout the world in tropical and subtropical regions around the world, becoming naturalized or invasive in many ...
Castor oil. Castor oil is a vegetable oil pressed from castor beans, the seeds of the plant Ricinus communis. [1] The seeds are 40 to 60 percent oil. [2] It is a colourless or pale yellow liquid with a distinct taste and odor. Its boiling point is 313 °C (595 °F) and its density is 0.961 g/cm 3. [3]
Soda inermis, the opposite-leaved saltwort, oppositeleaf Russian thistle, or barilla plant, is a small (to 0.7 m tall), annual, succulent shrub that is native to the Mediterranean Basin. [1][2] It is a halophyte (a salt-tolerant plant) that typically grows in coastal regions and can be irrigated with salt water.
There are three primary types of plant oil, differing both the means of extracting the relevant parts of the plant, and in the nature of the resulting oil: Vegetable fats and oils were historically extracted by putting part of the plant under pressure, squeezing out the oil. Macerated oils consist of a base oil to which parts of plants are ...
Ascaridole was the first, and for a long time only, discovered naturally occurring organic peroxide.It was isolated from Chenopodium oil and named by Hüthig in 1908. He found that when heated to between 130° and 150° C "there occurs, with sudden boiling in which the temperature momentarily rises to about 250°, a decomposition of an explosive character, occasionally accompanied by ignition.
A 12% solution is widely used in waterworks for the chlorination of water, and a 15% solution is more commonly [38] used for disinfection of waste water in treatment plants. Sodium hypochlorite can also be used for point-of-use disinfection of drinking water, [ 39 ] taking 0.2–2 mg of sodium hypochlorite per liter of water.
Infobox references. Sodium carbonate (also known as washing soda, soda ash and soda crystals) is the inorganic compound with the formula Na2CO3 and its various hydrates. All forms are white, odourless, water-soluble salts that yield alkaline solutions in water. Historically, it was extracted from the ashes of plants grown in sodium-rich soils ...
A cross-linked polyethylene (PEX) pipe. Cross-linked polyethylene, commonly abbreviated PEX, XPE or XLPE, is a form of polyethylene with cross-links.It is used predominantly in building services pipework systems, hydronic radiant heating and cooling systems, domestic water piping, insulation for high tension (high voltage) electrical cables, and baby play mats.
