Английская Википедия:Diacetyl peroxide
Diacetyl peroxide is the organic peroxide with the formula (CH3CO2)2. It is a white solid or oily liquid with a sharp odor.[1] As with a number of organic peroxides, it is explosive.[2] It is often used as a solution, e.g., in dimethyl phthalate.[3]
History
Diacetyl peroxide was discovered in 1858 by Benjamin Collins Brodie,[4] who obtained the compound by treating glacial acetic acid with barium peroxide in anhydrous diethyl ether.[5]
Preparation
Diacetyl peroxide forms upon combining hydrogen peroxide and excess acetic anhydride. Peracetic acid is an intermediate.[6]
Safety
Consisting of both an oxidizer, the O-O bond and reducing agents, the C-C and C-H bonds, diacetyl peroxide is shock sensitive and explosive.[7][8][3]
The threshold quantity for Process Safety Management per Occupational Safety and Health Administration 1910.119 is Шаблон:Convert if the concentration of the diacetyl peroxide solution is greater than 70%.[9]
There have been reports of detonation of the pure material. The 25% solution also has explosive potential.[10] The crystalline peroxide is especially shock sensitive and a high explosion risk.[11][8]
Safety
Organic peroxides are all prone to exothermic decomposition, potentially leading to explosions and fire.[12]
Contact with liquid causes irritation of eyes and skin. If ingested, it irritates mouth and stomach.[13][14][15][16]
