Lead acetate, also known as lead acetate, commonly known as lead sugar.Chemical formula (CH3COO) 2Pb, Mr=325, usually refers to trihydrate, there are also decahydrate and anhydrous.
Lead acetate trihydrate is colorless crystal, white particles or powder, slightly acetic acid smell, has weathering, toxic.Melting point 60-62ºC, boiling point 280ºC (atmospheric pressure), 15ºC solubility 45.6, 100ºC 200.
Used for preparation of various lead salts, antifouling coatings, water quality protective agents, pigment fillers, paint desiccants, fiber dyes and solvents for heavy metal cyanidation.
Physical and chemical properties
three
Lead acetate, white monoclinic crystal, density 2.55g?Cm-3 (25ºC).Melting point 75ºC (hot).Combustible.A slight odor of acetic acid.Having the property of weathering.Refractive index 1.567.It is a covalent compound and a weak electrolyte.Soluble in water, solubility 55.04g/100g water.It is also soluble in glycerol and insoluble in ether.Anhydrous lead acetate was formed from water loss at 75ºC.
Lead acetate decahydrate, white orthogonal crystal, density 1.69g?Cm-3 (25ºC).It is easy to lose water by weathering at normal temperature.Weak electrolyte.Soluble in water, soluble in glycerol, insoluble in ether.
Anhydrous lead acetate, white powder, density 3.75g?Cm-3 (20ºC).Melting point is 280 ºC.Weak electrolyte.Soluble in water, solubility 44.3g/100g water.Insoluble in ether.
In the presence of acetic acid, methyl acetate, lead iodide and carbon dioxide are produced when lead acetate interacts with iodine:
When lead acetate interacts with excessive iodine, carbon dioxide, methyl iodide and lead iodide are generated:
When lead acetate is heated with iodine and water, lead iodide, lead iodate and acetic acid are formed:
When aluminum sulfate interacts with lead acetate, the basic aluminum acetate, acetic acid and lead sulfate are formed:
Basic lead carbonate is formed when a moderately dilute solution of lead acetate is heated to near the boiling point.If the solution concentration is high, lead carbonate will be formed.

Production methods
1. Lead oxide reacts with acetic acid.Lead oxide was dissolved in 80% hot acetic acid until it was dissolved in bubbles, filtered, and then evaporated to a relative density of 1.40 after adding a small amount of acetic acid to the filtrate.Cooling, filtering, drying, lead acetate.The general purity of lead acetate in industrial products can reach more than 98%.After purification, recrystallization of 1% acetic acid solution is available, or lead acetate trihydrate is dissolved in water through hydrogen sulfide, so that lead sulfide and other impurities precipitated together, after filtration, add fluorescent gallium reagent (Co,Al,Cu, etc. Complex agent) in the filtrate, add a small amount of activated carbon, and add EDTA sodium salt treatment, can be very pure reagent grade products.
2. Dissolve lead oxide (II) in 50% acetic acid until saturated.Filtrate, add a little acetic acid in the filtrate, evaporate on the water bath to a relative density of 1.40, let stand, crystal precipitation.Extraction filter, placed between the filter paper drying, pure.Place the product in the air.It can absorb carbon dioxide, ammonia and other gases in the air to produce carbonate or basic salt, which can be purified by recrystallization of 2% ~ 3% acetic acid aqueous solution.100g lead acetate requires 100mL 2% ~ 3% acetic acid solution. After being heated and dissolved, the insoluble substance is filtered out while the filtrate is hot. After the filtrate is cooled, it is allowed to stand for crystal precipitation.Concentrate the mother liquor to half of the original volume, add a small amount of acetic acid after cooling, but also can get part of the product.
3. Dissolve lead oxide in hot acetic acid, after filtration, add acetic acid reaction to the filtrate, and evaporate to a relative density of 1.40.After cooling, the crystals were separated and dried, the pure lead acetate was obtained.
Application
1. The product can be made of various lead salt, anti-fouling paint, water quality protection agent, pigment filler, paint desiccant, fiber dyeing agent, heavy metal cyanide process solvents.It is widely used in the industrial production of medicine, pesticide, dye and coating.It is also a reagent for the determination of chromium trioxide and molybdenum trioxide in chemical analysis.As an analytical reagent, it is also used in biological dyeing, organic synthesis and pharmaceutical industry.
2. Analytical reagent, used for the determination of sulfide, chromium trioxide, molybdenum trioxide, biological staining and organic synthesis.
3. For biological dyeing, organic synthesis and pharmaceutical industry.
