colorless transparent liquid, a weak acid, a strong irritating acetic acid odor, volatile. Soluble in water and organic solvents, solubility similar to acetic acid. Active oxygen content is generally about 21%, is a peroxide, chemical reaction activity is high, and organic matter, reducing agent, flammable materials such as sulfur, phosphorus, etc. when in contact with or mixed with the risk of combustion explosion. Flammable, heated to 100 ° C that is violent decomposition, contact with open flame, high heat or by friction vibration, impact can be an explosion.
obtained by the reaction of acetic acid and hydrogen peroxide in the presence of sulfuric acid. Or cobalt acetate, tartrate as a catalyst, with acetone or ethyl acetate as a solvent, under a certain temperature and pressure, air directly into the acetaldehyde solution oxidation to produce peroxyacetic acid.
is a green ecological fungicide, without any residue in the environment. It has good compatibility with some commonly used scale and corrosion inhibitors in cooling water. Sterilization ability, can be used as a disinfectant for circulating cooling water and oil field water treatment, can also be used for infectious diseases Disinfection, drinking water Disinfection, fabric Disinfection and food industry. Is a very promising fungicide, its performance is better than glutaraldehyde and isothiazolinone. Peracetic acid is also used as a bleaching agent for textiles, paper, grease, paraffin and starch. In organic synthesis as oxidation and epoxide for propylene oxide, glycerol, caprolactam synthesis.
rat oral LD50:1540mg/kg; Guinea pig oral LD50: 10mg/kg; Rabbit percutaneous LDso:1410mg/kg I rat inhalation LCso: 450mg/kg. Toxic, strongly irritating to the skin and eyes. Staff should be protected. Peracetic acid is unstable, the storage process will gradually natural decomposition, in the light or heating, easy to cause rapid decomposition and explosion. Store in a dark and cool place at a temperature below 10 °c. Avoid putting together with organic products. According to the provisions of toxic, flammable and explosive chemicals storage and transportation.
