A process tor the manufacture of artificial essence of violets consisting in causing lemon-grass oil, alcohol, acetone, and concentrated solutions of salts of hypochlorous acid to react on one another at the boiling temperature. 

As demand for alkalis soared, more and more trees and plants were burned in Western Europe and North America. Each September, peasants along the coasts of Spain and southern France collected the highest quality alkali coastal barilla grasses impregnated with sea salt. The peasants dried... 

With aridity increasing, various plant species of forage crops become gradually less numerous to finally disappear. In Dry Steppe ecosystems xerophylic half-shrubs and salt-tolerant plants replace the grasses. However, the ash content is higher in these species. This is attributed not only to a higher concentration of major ash elements in the plant tissue, but also to the exposure to finely dispersed dust adhered to the plants exterior (Table 9). 

Quinone may be prepared by the oxidation of aniline with dichromate or manganese dioxide and sulfuric acid.1 This is a more feasible commercial method than the one given. However, the oxidation of hydroquinone is more rapid and convenient and, hence is more desirable for use in the laboratory. Various materials have been oxidized by chemical means to give quinone they are quinic acid,2 hydroquinone,3 benzidine,4 -phenylene-diamine,5 sulfanilic acid,6 / -phenolsulfonic acid,7 arbutin,8 aniline black,9 and the leaves of various plants.10 Quinone is also formed by several other methods by the fermentation of fresh grass 11 by the action of iodine on the lead salt of hydroquin-... 

In the trunk, we "stow two bags of grass, seventy-five pellets of mescaline, five sheets of high-powered blotter acid, a salt shaker half full of cocaine, and a whole galaxy of multicolored uppers, downers, screamers, laughers,. .. a quart of tequila, a quart of rum, a case of Budweiser, a pint of raw ether and two dozen amyls."... 

It is estimated that over 100,000 acres in Hawaii and some 250,000 acres in Louisiana each year are treated with herbicides, mostly 2,4-D and TCA (sodium salt of trichloroacetic acid), for pre- and postemergence weed control. Johnson grass on ditch banks on some 50,000 to 75,000 superficial acres in Louisiana is controlled with sodium chlorate or TCA. Some trials with CMU [3-(p-chlorophenyl)-l,l-di-methylurea] are in process. Florida cane growers use 150,000 pounds of 2,4-D amine salt of Karmex W on 43,000 acres of cane and anticipate using up to 100,000 pounds per year. Of the growers in Puerto Rico, 60% are said to use herbicides as either pre- or post-emergence sprays. 

Saltmarsh A relatively flat area of the shore where fine-grained sediment is deposited and salt-tolerant grasses grow. One of the most biologically productive ecosystems on Earth s surface. 

Dry salt grass, Distichlis stricta, has high levels of phenolics after fruiting. Cinnamic acids and their vinyl phenols lower uterus weight, inhibit follicular development, and lead to cessation of reproductive activity in the montane vole Microtus montanus. Specific active compounds are 4-vinylguaiacol and 4-vinylphenol, and alsop-coumaric acid (4-hydroxycinnamic acid) (Berger etal, 1977). 

Uses. Herbicide marketed as the sodium salt or a mixture of the sodium and magnesium salts used to control grasses in a wide variety of crops and in a number of noncrop applications, such as along drainage ditches and railroads and in industrial areas. 

Potassium was first isolated as a free metal in 1807 by Sir Humphry Davy. It was the first alkali metal to be discovered, produced by electrolysis of potassium carbonate (potash). The element was earlier called Kalium, derived from the Arabic word qili, meaning grass wort, the ash of which was a source of potash. The element derived its symbol K from Kalium. The English name potassium came from potash (pot ash), the carbonate salt of the metal.
