Nature
colorless crystal or white powder. Slightly acetic acid. mp 60~62 C I d 2.55. Soluble in water, slightly soluble in alcohol, soluble in glycerol. lg the product is soluble in 1-6ml water, 0.5ml boiling water, 30ml ethanol, soluble in glycerol. After absorption of carbon dioxide in air, it becomes an insoluble basic carbonate. The acetic acid was lost at 100 °c and completely decomposed at 200 °c. Flammable in case of open flame and high heat. By high heat decomposition of toxic gases.
Use
Analytical reagents for the determination of sulfide, chromium trioxide, molybdenum trioxide, biological dyeing and organic synthesis.
Preparation Method
lead oxide was dissolved in hot acetic acid, and after filtration, acetic acid was added to the filtrate to react and evaporated to a relative density of 1-40. After cooling, the crystals were isolated and dried to obtain pure lead acetate.
Safety
mice were injected intravenously with LD50:174mg/kg. According to RTECS standard, it was suspicious for tumor. The maximum allowable concentration of harmful substances in the air of the workshop is 0. 05mg/m3. Staff should be protected and immediately rinsed with running water when touching eyes and skin. It is strictly prohibited to mix with acids, oxidants, food and food additives.
Reference Information
| introduction | lead acetate trihydrate is colorless crystal, white particles or powder, which will deliquesce. Easily soluble in water with sweet taste. Lead acetate trihydrate is used to make various lead salts, pigments, dyes, lead plating, polyester catalysts, waterproof paints, desiccants, pesticides and medicines. |
| safety information | lead acetate trihydrate rats were given LD50130mg/kg orally and 120 mg/kg intravenously. the metabolic symptoms after absorption in the body were the same as those of common inorganic lead compounds. The United Nations, the International Maritime Organization, the United States and the United Kingdom classify it as a toxic and dangerous substance, and there are corresponding regulations and restrictions when storing, transporting, packaging and treating as waste. |
| solubility in water (g/100ml) | dissolution grams per 100ml of water at different temperatures (℃): 19.8g/0 ℃;29.5g/10 ℃;44.3g/20 ℃;69.8g/30 ℃;116g/40 ℃ |
| use | used as pigment, stabilizer and catalyst this product can produce various lead salts, anti-fouling coatings, water quality protection agents, pigment fillers, paint desiccants, fiber dyes, and solvents in the cyanidation process of heavy metals. It is widely used in medicine, pesticides, dyes, coatings and other industrial production. It is also a reagent for the determination of chromium trioxide and molybdenum trioxide in chemical analysis. Used as an analytical reagent, also used in biological dyeing, organic synthesis and pharmaceutical industry |
| production method | lead oxide reacts with acetic acid. Dissolve lead oxide in 80% hot acetic acid until it is soaked, filter, add a small amount of acetic acid to the filtrate, and evaporate to a relative density of 1.40. Cool, filter, and dry to get lead acetate. The general purity of industrial lead acetate can reach above 98%. After purification, recrystallize with 1% acetic acid solution, or dissolve lead acetate trihydrate in water and pass hydrogen sulfide to precipitate lead sulfide and other impurities. After filtration, fluorescent gallium reagent (Co,Al,Cu, etc.) is added to the filtrate, a small amount of activated carbon is added, and EDTA sodium salt is added to obtain extremely pure reagent grade products. |
