Potassium Sulfate. Potassium sulfate is a preferred form of potash for crops that have a low tolerance for chloride. Tobacco and potatoes ate two such crops. K2SO4 is produced most often from langbeinite by metathetical reaction in aqueous solution ... 

Four minerals are the principal commercial sources of potash (Table 2). In all ores, sodium chloride is the principal soluble contaminant. Extraneous water-iasoluble material, eg, clay and siUca, is a significant contaminant ia some of the evaporates being mined from underground deposits. Some European potassium ores contain relatively large amounts of the mineral kieserite, MgS04-H2 0. It is recovered for captive use to produce potassium sulfate compounds or is marketed ia relatively pure form as a water-soluble magnesium fertilizer. 

Potassium chloride [7447-40-7] or muriate of potash (MOP) as it is known in the fertilizer industry (at about 97% purity), is the world s most commonly used potash (5). Chemical-grade potassium chloride (99.9%) is the basis for manufactured production of most potassium salts (10). 

Economic Aspects and Uses. Total world production of potassium products is 29,000,000 tons per year (65). Potassium chloride is removed from brine at Moab, and Wendover, Utah, and at Seades Lake, California. Potassium sulfate is made from Great Salt Lake brine by Great Salt Lake Minerals Corp., which is the largest producer of solar potassium sulfate in the wodd. Combined, these U.S. faciUties stiU produce a relatively small percentage of potash fertilizers in the wodd. Production from the Dead Sea, for example, is 10 times greater than production of potassium from brines in the United States. More than 95% of all the potassium produced is used in fertilizer blends. The remainder is converted to other potassium chemicals for industdal use (see Potassium compounds). 

The industrial term potash can be very misleading. It can refer to potassium carbonate (K2CO3), potassium hydroxide (KOH), potassium chloride (KCl), potassium sulfate (K2SO4), potassium nitrate (KNO3), or collectively to all potassium salts and to the oxide K2O. More correctly KOH is called caustic potash and KCl is called muriate of potash. Production is recorded in weight equivalents of K2O since almost all potash is used as fertilizer and this industry quotes weight percentages of K2O in its trade. 

Walden concluded that potassium hydrate and phosphorus penta-chloride acted optically normally, i.e. without alteration of the configuration, but that silver oxide, and therefore also nitrous acid and nitrosyl chloride, acted optically abnormally, but as to which of these reactions was really the normal one he was not able to decide. The conclusion was remarkable, since the action of silver oxide takes place in aqueous. solutions at a low temperature and the effect of potash in producing racemisation is well known. Still more curious is the supposition that nitrous acid and nitrosyl chloride act optically abnormally. 

The reagents used for the METLCAP technology are readily available and fairly inexpensive, as magnesium chloride is a commercially available by-product from the production of potash (D12759N, p. 8). 

By the action of water upon the chloride of fi chlorpropionyl, a body of the composition of chloropropionic add is obtained but inasmuch os this body yields paralactic acid by ebullition with potash, whilst chloropropionic acid gives under the same drcumstances lactic acid, it follows that the former ohloro-add must be isomeric, and not identical, with the latter. Now, dthough the formula of propionic add does not admit of any isomer, yet that of cbloropropionio add does, os is scon in the following graphic formuhe... 

The brines of the Lonar Lake, Buldana district, India,11 are said to contain 01 per cent, of potash calculated on the soluble salts. In Tunis, south of Gabes, there is a salt-lake worked since 1915, primarily for bromine a crude potassium chloride—40 per cent. K20—called sebkainite, is obtained by solar evaporation and crystallization. In 1917, 20,000 tons were produced. The brines of several alkali lakes and ponds in Western Nebraska contain appreciable quantities of potash— the brine is reported to contain the eq. of about 3 per cent, of potash (K20), and...
