Technical Field

The invention relates to the technical field of lead acetate, and particularly relates to lead acetate and a preparation method thereof.

Background

Lead acetate, also known as lead acetate, commonly known as lead sugar, of the chemical formula (CH3COO)2Pb, Mr 325, commonly referred to as trihydrate, also decahydrate and anhydrate, is colorless crystals, white granules or powder, slightly smells of acetic acid, has the properties of being mineralized, toxic, 60-62 ℃ in melting point, 280 ℃ in boiling point (normal pressure), 45.6 in solubility at 15 ℃ and 200 at 100 ℃, and is used for preparing various lead salts, anti-fouling coatings, water quality protectants, pigment fillers, coating desiccants, fiber coloring agents and solvents in heavy metal cyanidation;

the existing lead acetate production process needs a reaction kettle for reaction production, the production cost is high, the grain size of the produced lead acetate is large and is more than 3mm, and the lead acetate needs to be processed when being used at the later stage, so that the demand of people is difficult to meet.
