Fairways, Roughs, Sports Turf and Lawns: Apply 3.1 - 4.1 gallons of Ammonium Thiosulfate with 44 - 88 gallons of water per Acre (9.0 - 12.0 oz. indirect food additives: adhesives and components of coatings, diazanium dioxido-oxo-sulfanylidene-lamda6-sulfane, FDA PART 175 -- INDIRECT FOOD ADDITIVES: ADHESIVES AND COMPONENTS OF COATINGS, Atomic Weights of the Elements 2011 (pdf). Sulfur deficiency can affect the plant’s ability to utilize nitrogen for protein synthesis. This reaction, commonly known as the Claus reaction, occurs from the reaction of H2 S and SO2, which produces water and solid particulate sulfur. 3,524,724 requires additional sulfur dioxide to be added in a second stage to the solution of ammonium bi-sulfate. It is not necessary to evaporate water from the solution to produce a standard 60% by weight ammonium thiosulfate solution. Privacy Policy If it is desired to feed a gas to the B-2 burner with a low H2 S content, sufficient liquid sulfur will not be produced for the later needed subsequent reactions. (NH4)2 SO3 +SO➝(NH4)2 S2 O3 5. Ammonium Thiosulfate is an excellent source of ammoniacal nitrogen that is quickly absorbed by the plant. View information & documentation regarding Ammonium thiosulfate, including CAS, MSDS & more. Ammonium thiosulfate CAS:7783-18-8 manufacturer, Ammonium thiosulfate supplier, Ammonium thiosulfate producer from China, offering highest quality Ammonium thiosulfate to global customers. No. It is a high-tech pharmaceutical chemical company integrating R&D, production and sales. Sigma-Aldrich offers a number of Ammonium thiosulfate products. Lethal, sublethal, and behavioral effects of sulfur-containing products in bioassays of three species of orchard mites. Then nitrogen, water and traces of SO2 and NH3 are vented from V-2. Repeat as needed every 7 - 14 days during active growth period. The solution density from the bottom of V-2 is brought to the specific gravity of from about 1.2 to about 1.3 and preferably to about 1.24 before flowing to the reaction tank T-2. The foregoing disclosure and description of the process is illustrative and explanatory thereof and various changes in the size, shape and materials, is in the details of the illustrated construction, may be made within the scope of the appended claims without departing from the spirit of the invention. The equilibrium in reaction 3 is shifted to the right which makes the ammonium sulfite, (NH4)2 SO3 available for reaction with sulfur to produce the ammonium thiosulfate. NH3 is added to the solution in the bottom of the second reaction zone in the liquid phase. 3,431,070; by reacting ammonium bi-sulfite solution, ammonia, sulfur and catalytically acting amounts of hydrogen sulfide in a first stage and then reacting the solution with sulfur in a second stage, U.S. Pat. Referring again to FIG. The hot solution from V-1 is pumped by P-2 to air cooler AF-2. Quality supplier of research chemicals and biochemicals including inhibitors, building blocks, GMP Products, impurities and metabolites, APIs for Veterinary, Natural Compounds, ADCs, Stem Cell Molecule and chiral compounds. An excess of ammonium sulfide would result in the Claus reaction which produces the type of solid sulfur that may plug up the system. In addition, any carbon dioxide in the combustion gases will not react with the ammonia at this temperature and will pass through the system as an inert gas. 1, sulfur is maintained in a molten state in the sulfur tank P-1 by a steam coil. Global manufacturer, producer & supplier of Ammonium thiosulfate (CAS No. The ammonia must be added in V-2. For example, U.S. Pat. The dense solution flows from the bottom of V-2 via line 11 through valve 22a to T-1. 2NH4 HSO3 ⇋(NH4)2 SO3 +SO2 +H2 O 4. burning elemental sulfur by air combustion to produce SO2 ; reacting SO2, substantially free of sulfides and oxygen, in a first reaction zone in the presence of a circulating solution of (NH4)OH, (NH4)2 SO3 and NH4 HSO3 to remove most of the SO2, said circulating solution being free of (NH4)2 S2 O3 ; cooling said circulating solution to not more than about 180° F. and passing said solution to a second reaction zone along with any remaining SO2 from the first reaction zone to remove substantially all of said remaining SO2 ; adding sufficient amounts of NH3 to said solution in the second reaction zone to maintain the pH of said solution in said second reaction zone from about 5 to about 7 and the density of said solution in said second reaction zone from about 1.2 to about 1.3; passing said circulating solution to a third reaction zone which is separate from said first and second reaction zones and wherein a molar excess of liquid sulfur, as the sole source of sulfur values is sprayed into said solution to provide sulfur in a particulate form suitable for reaction with ammonium sulfite to produce ammonium thiosulfate; maintaining the temperature in said third reaction zone, in a range of from about 140° F. to about 220° F.; burning elemental sulfur and H2 S rich gas by air combustion to provide a combustion product containing SO2 ; reacting SO2, substantially free of sulfides and oxygen, with a circulating solution of (NH4)OH, (NH4)2 SO3 and NH4 HSO3 but free of (NH4)2 S2 O3 to provide ammonium sulfite, and passing said solution through a cooling zone to a second reaction zone along with any remaining SO2 from the first reaction zone to remove substantially all of said remaining SO2 ; adding a sufficient amount of NH3 to said solution in the bottom of said second reaction scrubber zone below the liquid level in order to maintain the pH of said solution in said second reaction zone at from about 5 to about 7 and the density of said solution in said second reaction zone at from about 1.2 to about 1.3; passing said solution to a third reaction zone and spraying said solution therein with a molar excess of sulfur as the sole source of sulfur values to provide sulfur in a particulate form suitable for reaction with ammonium sulfite to produce ammonium thiosulfate; maintaining the temperature in said third reaction zone in a range of from about 170° F. to about 190° F.; adding NH3 to provide ammonium hydroxide in said third reaction zone in sufficient amounts to bind the SO2 produced by the equilibrium reaction of ammonium bisulfite to ammonium sulfite, sulfur dioxide and water while maintaining the pH at 5-7; circulating said solution in said third reaction zone for a sufficient amount of time for the reaction to complete; and.
