Acetophenone (98-86-2)

?Acetophenone (CAS NO.98-86-2) is also named as 1-Phenyl-1-ethanone ; 1-Phenylethanone ; AI3-00575 ; Acetofenon ; Acetofenon [Czech] ; Acetophenon ; Acetylbenzene ; Acetylbenzol ; Benzene, acetyl- ; Benzoyl methide ; Benzoylmethide ; CCRIS 1341 ; Ethanone, 1-phenyl- ; FEMA No. 2009 ; FEMA Number 2009 ; HSDB 969 ; Hypnone ; Ketone, methyl phenyl ; Methyl phenyl ketone ; NSC 7635 ; Phenyl methyl ketone ; RCRA waste number U004 ; UNII-RK493WHV10 ; USAF EK-496 .?Acetophenone (CAS NO.98-86-2) is yellow liquid with a sweet pungent taste. It is slightly soluble in water. Vapor heavier than air. A mild irritant to skin and eyes. Vapors can be narcotic in high concentrations. Acetophenone reacts with many acids and bases liberating heat and flammable gases (e.g., H₂). Reacts with many oxidizing agents. Reacts with reducing agents such as hydrides, alkali metals, and nitrides to produce flammable gas (H₂) and heat. The amount of heat in these reactions may be sufficient to start a fire in the unreacted portion. It ia incompatible with isocyanates, aldehydes, cyanides, peroxides, and anhydrides. No toxicity expected from inhalation or ingestion except slight narcotic effect. Liquid can cause eye and skin irritation on contact.

In perfumery to impart an orange-blossom-like odor, catalyst for polymerization of olefins, in organic synthesis, esp as photosensitizer.
