Lead lead acetate, also known as acetic acid, commonly known as lead sugar [1].
Chemical formula (CH3COO) 2 pb, Mr =325, usually refers to the three hydrate, also have ten hydrate and anhydride [2]. Lead acetate trihydrate colorless crystalline, white granular or powder, slightly acid smell, weathering resistance, toxic.
60-62 ℃ melting point, boiling point 62 ℃ (atmospheric pressure), 15 solubility was 45.6 ℃, 100 ℃ for 200.[3]
Used for the preparation of a variety of lead salt, anti fouling paint, water quality protection agent, pigment, filler, paint desiccating agent, fiber dyeing agent and solvent in the process of heavy metal cyanide.[2]
