Product Name * Aluminum Product rating Industrial Content ≥ 15.5 * Aluminum (chemical formula Al2 (SO4) 3, formula weight 342.15), white orthorhombic crystalline powder, density 1.69g / mL (25 ℃). In the paper industry as rosin, wax emulsion rubber precipitants, flocculants for water treatment, the agent can be made to stay foam fire extinguisher, manufacturing alum, aluminum white raw materials, oil bleaching, deodorization agent, some drugs and other materials. Also the manufacture of artificial stones and senior ammonium alum. Approximately 50% of total output * Aluminum is the first major use for the paper, the second largest use is made flocculants in drinking water, industrial water and wastewater treatment industry, which accounts for 40% of total production * aluminum. When water is added to such * aluminum, can generate colloidal can absorb and precipitate the bacteria, colloidal suspensions and other aluminum hydroxide flakes used in drinking water treatment can control the color and flavor. Chinese Name CAS No. EINECS No. InChI * Aluminium 10043-01-3 233-135-0 1S / 2Al.3H2O4S / c ;; 3 * 1-5 (2,3) 4 / h ;; 3 * (H2,1, 2,3,4) / q2 * + 3 ;;; / p-6 English name MDL No. RTECS No. aluminum sulfate MFCD00003423 BD1700000 2 physicochemical properties of the physical properties of aluminum structural formula * * Aluminum Structure Appearance: white crystal, has a sweet taste; Solubility: soluble in water, insoluble in ethanol. Industrial products for white flake, granular or block, because it contains low iron salts with pale green, because leaving the surface is oxidized ferric cheap yellow. Crude off-white fine crystalline structure of the porous substance. Easily soluble in water, * * pure aluminum can not be dissolved (just coexist), and * in * the solution jointly dissolved in water, so the solubility of aluminum in * * * is the solubility of aluminum in water. 770 ℃ decomposed into alumina and sulfur trioxide. Anhydrous and eighteen hydrates. Anhydrous colorless orthorhombic crystals. Soluble in water, aqueous acidic, slightly soluble in ethanol. Solubility in water increases with temperature increases. Eighteen hydrate (Al2 · (SO4) 3 · 18H2O) as a colorless monoclinic crystal. Dissolved in water, soluble in ethanol. Acidic aqueous solution due to hydrolysis. Relative density (water = 1): 2.71 * Aluminum difficult to weathering and chemical properties and loss of crystal water, relatively stable, heat will dehydrate, temperatures will be decomposed into alumina and sulfur oxides. Was heated to 770 ℃ begins to decompose alumina, sulfur trioxide, sulfur dioxide and water vapor. Dissolved in water, acid and alkali, insoluble in ethanol. Acidic aqueous solution. Aluminum hydroxide hydrolysis. Boiling water for a long time to generate basic * aluminum. Toxic dust can irritate the eyes. There are basic salts and hydrolysis products of aluminum hydroxide gel precipitate. Easy to form alum with potassium, sodium, ammonium salts in combination, such as the * aluminum potassium kAl (SO4) 3 · 12H2O. Heating hydrate, violent swell and become sponges, when heated to a red heat, the decomposition of sulfur trioxide and alumina. Toxicity: ADI not specified (FAO / WHO, 2001). GRAS (FDA, §182.1125,2000). LD50: 980 ± 90 mg / kg (mice). Note Explosion Hazards: This product is flammable, irritating. [4] health hazards: the eyes, mucous membranes have a stimulating effect. * A lot of oral ingestion of aluminum and stomach irritation effect. Toxicological Information: mouse oral LC50: 6207mg / kg. [5] Ecological Information: Normally the water body is slightly harmful, not to undiluted product or large quantity reach ground water, water course or sewage system, without government permission Do not allow material into the surrounding environment. Skin contact: Remove contaminated clothing, mobile water rinse. Eye contact: Did eyelid, mobile water or saline. Medical treatment. Inhalation: from the scene to fresh air. If breathing is difficult, give oxygen. Medical treatment. Ingestion: drink plenty of water, induce vomiting. Medical treatment. Hazardous characteristics: no special combustion characteristics of the explosion. Heat generated by the decomposition of toxic sulfide gas. Hazardous combustion products: natural decomposition products known. Fire fighting methods: firefighters must wear fire protective body suits, the wind on fire. Try to move containers from the scene empty Department when the fire. [6] Emergency treatment: Isolation leak contaminated areas, restricting access. Recommended emergency personnel wearing a dust mask (full cover), wear protective clothing. Clean shovel collection in a dry, clean, covered containers, transferred to a safe place. If large spills, recycling or collection shipped to the waste disposal sites. [7] Handling Precautions: closed operation, local exhaust ventilation. The operator must go through specialized training, strict adherence to rules. Proposed operators wear self-absorption filter respirators, wearing chemical protective safety glasses, wear protective overalls on infiltration, wear rubber gloves. Avoid creating dust. Avoid contact with oxidizing agents. When moving gently, packaging to prevent breakage. Equipped with spill response equipment. Empty containers may be harmful residues. Storage: Store in a cool, ventilated warehouse. Away from fire and heat. Should be stored separately and oxidant, avoid mixing reservoir. Storage areas should be equipped with suitable material spill. [8] Storage: When complete packaging to shipment, loading should be safe. During transport to ensure that the container does not leak, did not fall, do not fall, no damage. Strictly prohibited and oxidants, food chemicals mixed mixed operation. Transit should be anti-exposure, rain, anti-high temperature. Finished vehicle transport should be thoroughly cleaned.
