Irritant Smoke (Stannic Chloride) This qualitative fit test agent uses a person’s response to the irritating chemicals released in the “smoke” produced by a stannic chloride smoke tube to detect leakage into the respirator. STANNIC PHOSPHIDE is a reducing agent. With many other names, this oxide of tin is an important material in tin chemistry. Tannic acid can be applied to woods low in tannin so chemical stains that require tannin content will react. [8][9], In Allen's "Commercial Organic Analysis", published in 1912, the formula given was C19H16O10. Stannic Chloride, Hydratedis a white or yellow solid. Tannic acid reacts with the corrosion products to form a more stable compound, thus preventing further corrosion from taking place. It is also an alternative for fluorcarbon aftertreatments to impart anti-staining properties to polyamide yarn or carpets. Similarly tannic acid can also be used as an aftertreatment to improve wash fastness properties of acid dyed polyamide. Anhydrous Stannic Chloride, or Tin Tetrachloride, is used to apply thin-film tin oxide coatings on container and flat glass, as a raw material in the manufacture of PVC stabilizers, as a catalyst and is used in the manufacture of other tin based chemicals. Halogen acids attack SnO 2 to give hexahalostannates, [14] such as [SnI 6] 2−.One report describes reacting a sample in refluxing HI for many hours. Tannic acid is a common mordant used in the dyeing process for cellulose fibers such as cotton, often combined with alum and/or iron. Irritant smoke – a solid aerosol made of stannic oxychloride that produces hydrochloric acid when it comes in contact with water vapor.

This made the combination less effective. stannique.] If fitted and used properly, each respirator will provide adequate protection 4. [19], Skin color in Crocodilia (crocodiles and alligators) is very dependent on water quality. [17] During World War I, tannic acid dressings were prescribed to treat "burns, whether caused by incendiary bombs, mustard gas, or lewisite. Find out information about stannic sulfide. A stannic acid anhydride represented by the structural formula shown below. It is a colourless, diamagnetic, amphoteric solid. Tannic acid is also found in commercially available iron/steel corrosion treatments, such as Hammerite Kurust. Infom wearer that they are asked to select the respirator that provides the most acceptable fit. Google has not performed a legal analysis and makes no representation as to the accuracy of the status listed.) In his report of this discovery in 1904 he noted that the only known historical reference to the use of organic material added to clay is the use of straw mixed with clay described in the Bible, Exodus 1:11 and that the Egyptians must have been aware of his (re-)discovery. Tin(IV) compounds of significance include stannic chloride (SnCl4) is widely used as a stabilizer for perfumes and as a starting material for other tin salts; and stannic oxide(SnO2) is a useful catalyst in certain industrial processes and a polishing powder for steel. Stannic Oxide Stannic Oxide is used as a catalyst for the oxidation of aromatic compounds in the synthesis of carboxylic acids and acid anhydrides.

[citation needed], In conjunction with magnesium and sometimes activated charcoal, tannic acid was once used as a treatment for many toxic substances, such as strychnine, mushroom, and ptomaine poisonings in the late 19th and early 20th centuries.[16]. It is a yellow to light brown amorphous powder. Tannic Acid. Tannic acid is a lustrous, yellow-brown, amorphous tannin, having the chemical composition C 76 H 52 O 46.Commercial tannic acid is usually extracted from any of the following plant parts: Tara pods (Caesalpinia spinosa), gallnuts from Rhus semialata or Quercus infectoria or Sicilian Sumac leaves (Rhus coriaria). It differs however from the latter in not being convertible into gallic acid, and not yielding pyrogallic acid by dry distillation. We are manufacturer of Butyl Stannic Acid.Butyl Stannoic Acid is used primarily for synthesizing saturated polyesters (e.g powder coatings, roiled (steel) materials coatings, insulation paints etc. Ch. (Stenhouse, Ann. Stannic citric acid Safety Profile. Sometimes extracts from chestnut or oak wood are also described as tannic acid but this is an incorrect use of the term. [Note: NIOSH does not endorse or recommend the use of the irritant smoke fit test. resistance against dye bleaching due to cleaning with hypochlorite solutions in high-end polyamide 6,6-based carpets and swimwear. 28 (1943),1344. (Chem.) The tannin mordant should be done first as metal mordants combine well with the fiber-tannin complex. ), unsaturated polyesters, PBT engineering resins, and other esterified products. It is, however, used in relatively small quantities for the activation of upholstery flock; this serves as an anti-static treatment. xlv. Pharm. Combination of stannic chloride with turpentine is strongly exothermic, and may lead to ignition [Mellor, 1941, Vol. It generally does not have a smell, but the taste is one that can cause a person to pucker. Algae-laden waters produce greener skin, while tannic acid in the water from decay of leaves from overhanging trees (which produces some types of blackwater rivers) often produce darker skin in these animals.[20]. Tannic acid is also taken by mouth and applied directly for bleeding, chronic diarrhea, dysentery, bloody urine, painful joints, persistent coughs, and cancer. The E-number E181 is sometimes incorrectly used to refer to tannic acid; this in fact refers to the INS number assigned to tannic acid under the FAO-WHO Codex Alimentarius system. Each respirator represents d different size and fit. When said compound as it is, or the same coated on a substrate or impregnated into it, is baked, it is possible to finally form tin oxide which has excellent transparency and conductivity, ##STR1## wherein X represents ##STR2## 2. [12], Quercitannic acid was for a time a standard used to assess the phenolic content in spices, given as quercitannic acid equivalent. Disclaimer. Tin(IV) oxide, also known as stannic oxide, is the inorganic compound with the formula SnO2. With TMS (tetramethylsilane) used as the external standard, a sharp single line was observed at 160.9 ppm, and the UV spectrum had absorption maxima in the vicinity of 230, 260 and 300 nm, which correspond to the absorption maximum values of tin oxalate, oxalic acid, and meta stannic acid. Of or pertaining to tin; derived from or containing tin; specifically, designating those compounds in which the element has a higher valence as contrasted with {stannous}… Stannic definition, of or containing tin, especially in the tetravalent state. Compare Products: Select up to 4 products. Reacts quickly upon contact with acids to give the very toxic gas phosphine. Search results for stannic acid at Sigma-Aldrich. SnO2 wires are commonly used as the detecting element in carbon monoxide detectors. When used correctly it will produce an opaque, glossy glaze. Tannins are a basic ingredient in the chemical staining of wood, and are already present in woods like oak, walnut, and mahogany. A smell, but the taste is one of the status listed. precipitated.
