Perbenzoic acid

Perbenzoic acid 화학적 특성, 용도, 생산

• 화학적 성질

  Volatile solid with a pungent odor; sublimes;mp 41–43°C (105.8–109°F); bp 100–105°C(212–221°F) at 15 torr (partially decomposes); slightly soluble in water but mixesreadily with most organic solvents.

• 용도

  Perbenzoic acid is used to convert ethylenic compounds into oxides; in analysis of unsatd compounds, to determine the number of double bonds.

• 건강위험

  The toxicity of peroxybenzoic acid is verylow on animals. In humans it is almostnontoxic. Peroxybenzoic acid caused skintumor in mice on prolonged contact (NIOSH1986). Its tumorigenic action was lower thanthat of peroxyacetic acid. Its carcinogenicityin humans is unknown.

• 화재위험

  The presence of the peroxide functional group renders its strong oxidizing properties similar to those of other peroxy compounds. However, this compound is not hazardous like peroxyacetic or peroxyformic acids. It is not shock sensitive. Violent decomposition may occur only at high temperatures and/or in conjunction with certain organic contaminants that are easily oxidizable. Although there is no report of its explosion, general safety measures for handling peroxy compounds should be followed.

• Safety Profile

  Moderately irritating to skin, eyes, and mucous membranes by ingestion and inhalation. Questionable carcinogen with experimental tumorigenic data by skin contact. A dangerous fire hazard when exposed to heat, flame, or reducing materials. A powerful oxid

• Purification Methods

  Crystallise the peracid from *benzene or pet ether. It sublimes readily and is steam volatile. It is soluble in CHCl3, CCl4 and Et2O. [Braun Org Synth Coll Vol I 431 1941.] EXPLOSIVE.
