Health Hazard

Exposures to acetophenone oxime cause irritation to the eyes, skin, and the respiratory and digestive tracts. The toxicological properties of acetophenone oxime are not been fully investigated.

Safety Profile

Poison by an unspecified route.Slightly toxic by ingestion. When heated to decomposition itemits toxic vapors of NOx.

Synthesis

Add 6.4 ml (55 mmol) of acetophenone, 6 g (86 mmol) of hydroxylamine hydrochloride,4 ml of freshly distilled water and 20 ml of 95% ethanol to the reaction flask, and add 11 g (275 mmol) of solid sodium hydroxide in a batch in an ice bath, at which time the solution becomes a white turbid liquid, reflux at elevated temperature for five minutes, and then, after cooling, the solution is poured into a beaker containing 30 ml of concentrated hydrochloric acid and 200 ml of After cooling, the solution was poured into a beaker containing 30 ml of concentrated hydrochloric acid and 200 ml of water to obtain a white solid acetophenone oxime with a melting point of 58 C to 60 C.

storage

Acetophenone oxime should be kept stored in a cool, dry place and in a closed container when not in use.

Precautions

On exposures to acetophenone oxime, occupational workers should immediately fl ush the eyes with plenty of water. Workers should use proper personal protective equipment, wear appropriate gloves to prevent skin exposure, and wear appropriate protective eyeglasses or chemical safety goggles as described.
