FIELD OF THE INVENTION [0002] The present invention relates to a process for the preparation of potassium thiosulfate, or potassium sulfites and/or potassium bisulfites. BACKGROUND OF THE INVENTION 2 ~ 2 [0003] The thiosulfate ion, S20 , is a structural analogue of the S0 4 ion in which one ~2 oxygen atom is replaced by one S atom. However, the two sulfur atoms in S20 are not equivalent. One of the S atoms is a sulfide-like sulfur atom that gives the thiosulfate its reducing properties and complexing abilities. 0 S 1 I S S 0 < > 0::::::S::::::0 I I o _ o _ [0004] Thiosulfates are used in leather tanning, paper and textile manufacturing, flue-gas desulfurization, cement additives, dechlorination, ozone and hydrogen peroxide quenching, coating stabilizers, as an agricultural fertilizer, as a leaching agent in mining, and so on. [0005] Due to these complex-forming abilities with metals, thiosulfate compounds have also been used in commercial applications such as photography, waste treatment and water treatment applications. [0006] Thiosulfates do however readily oxidize to dithionates, trithionates, tetrathionates, and finally to sulfates: 2 → 2 2S 0 3 -+ 30 2S 0 - 2 → 2 S20 - + 0 2 2S0 4 2 → 2 2 ~ 7S20 3 + 3/202 2S30 +2S40 2 ~ → 2 ~ 2S 0 + 60 2 6S0 4 2 ~ → 2 ~ S40 + 50 2 4S0 4 [0007] Due to this transformation, thiosulfates are used as fertilizers in combination with cations such as ammonium, potassium, magnesium and calcium. The ammonium, alkali metal and alkaline earth thiosulfates are soluble in water. Water solubilities of thiosulfates decrease from ammonium to alkali metals to alkaline earth thiosulfates. [0008] Potassium (K) is a primary plant nutrient. Potassium is associated with movement of water, nutrients, and carbohydrates in plant tissue. If potassium is deficient or not supplied in adequate amounts, growth is stunted and yields are reduced. Potassium stimulates early growth, increases protein production, improves the efficiency of water use, is vital for stand persistence in cold weather, and improves resistance to disease and insects. [0009] Potassium thiosulfate fertilizer contains the highest percentage of potassium in liquid form, compared to other sources of potassium such as potassium chloride (KC1), potassium nitrate (KN0 ), and potassium sulfate (K2S0 4). In addition, it combines potassium with sulfur (17%) which is also an essential plant nutrient. [0010] It is contemplated that potassium thiosulfate could be produced by several alternative routes such as: I. Reaction of S and S0 2 in neutral or alkaline medium 2 2 2 II. Reaction of S and S0 (via S0 2 and HS0 ) III. Oxidation of Potassium Hydrosulfide (KSH) . Ion Exchange reaction between alkaline thiosulfates and potassium chloride or nitrate V. Salt exchange between alkaline thiosulfates and Potassium Chloride or Nitrate VI. Oxidation of Potassium Polysulfide [0011] However, some of these alternatives present serious difficulties or disadvantages. Route I and II are longer processes and require the use of sulfur dioxide S0 2. Both these routes are described when the scrubbing of the air pollutant sulfur dioxide is an objective. Route III requires handling of potassium hydrosulfide as a raw material which is not favorable due to a hydrogen sulfide environment. Routes IV and V suffer from the drawback that ion exchange and salt exchange require expensive raw materials and equipment, and also require a step of final stripping due to the need for working with dilute solutions. The prior art has been unsuccessful producing high purity potassium thiosulfate via Route VI with low byproducts. Thiosulfates, in general, are susceptible to further conversion to sulfite and sulfate under adverse temperature, and pressure. SUMMARY OF THE INVENTION [0012] Described herein are processes, preferably continuous, for the preparation of potassium thiosulfate in relatively high concentration with relatively low amounts of soluble or solid byproducts. The process may be used to produce a substantially clear solution having a relatively high percentage of potassium, and almost neutral pH, making it very suitable as a chlorine-free liquid fertilizer, for example as a foliar fertilizer, starter fertilizer, in furrow fertilizer and the like, and optionally in combination with other fertilizers. [0013] Also described herein are processes, preferably continuous, for the preparation of potassium sulfite, potassium bisulfite or mixtures thereof as a substantially clear solution having a relatively high percentage of potassium and almost neutral pH, making it suitable as a liquid fertilizer, for example as a foliar fertilizer, in furrow fertilizer and the like. [0014] Generally, the process of the present invention provides a method for preparing potassium thiosulfate, comprising the following steps: Step (la): providing a potassium hydroxide or potassium carbonate

  • General Chemical Resistance of a Fluoroelastomer Coatings & Sealants Fluoroelastomer
    General Chemical Resistance of a Fluoroelastomer Coatings & Sealants Fluoroelastomer www.pelseal.com Pelseal Technologies’ state-of-the-art fluid coatings, surface area to volume. Therefore, the ratings in the caulks, adhesives and sealants are manufactured from accompanying listing should be used only as a general fluoroelastomer rubber. Our products resist attack, to guide, not as specific recommendations. varying degrees, by a broad spectrum of industrial chemicals, fuels, oils, and other substances. While the information is presented by us in good faith, no guarantee, expressed or implied, can be given regarding We have researched the effect of the listed chemicals the accuracy of these ratings. on fluoroelastomers at various temperatures, concentrations, and exposure times. Our information is based on extensive In those cases where no data are available, the rating laboratory tests and experiments that have been performed shown is the considered, conditional opinion of experienced on fluoroelastomers themselves by a number of outside rubber chemists and compounders. organizations, including manufacturers, end users, suppliers, and trade associations. We strongly urge you to test our products under actual or simulated service conditions, before you purchase them, The information is believed to be reliable. However, the rather than assume that they will perform satisfactorily in degree of fluid resistance of an elastomer to deterioration your specific application. In order to assist you in learning by a specific substance is dependent on many variables, more about the chemical resistance of Pelseal's products including the concentration and temperature of the material; to the substance shown, the following rating code has the frequency and duration of exposure; the velocity of been used: flow and aeration; mechanical action; and the ratio of contact CODE E Excellent Resistance - little or minor attack by the material on fluoroelastomers; 0-5% volume swell where applicable.
