메틸(3-)-3-부텐-2-온 C화학적 특성, 용도, 생산
화학적 성질
Colorless or light yellow transparent liquid
용도
Plastics.
생산 방법
3-Methyl-3-buten-2-one is produced by acid-catalyzed condensation of 2-butanone with formaldehyde in the liquid phase.
A further possibility is the methylolization of 2-
butanone under alkaline conditions followed by
elimination of water:
일반 설명
A clear colorless liquid. Flash point of 52°F. Denser than water and insoluble in water. Hence sinks in water. Vapors heavier than air.
공기와 물의 반응
Highly flammable. Insoluble in water.
반응 프로필
3-Methyl-3-buten-2-one tends to polymerize; this reaction is mostly suppressed by the inhibitor. Can polymerize if heated or contaminated. If confined in a container when polymerization is initiated, the container may violently rupture [USCG, 1999].
위험도
Flammable, dangerous fire risk, explosivelimits in air 1.8–9.0%.
건강위험
Inhalation causes irritation of nose and throat. Liquid may cause severe damage to eyes, resulting possibly in some permanent impairment of vision; vapor produces tears. If not removed promptly from skin, liquid may cause delayed pain and blistering. Ingestion causes irritation of mouth and stomach.
화재위험
Behavior in Fire: May polymerize and explode.
화학 반응
Reactivity with Water: No reaction; Reactivity with Common Materials: No reaction; Stability During Transport: Stable; Neutralizing Agents for Acids and Caustics: Not pertinent; Polymerization: Will polymerize in the absence of inhibitor, especially when heated; Inhibitor of Polymerization: Up to 1% hydroquinone.
Safety Profile
Poison by ingestion and
skin contact. Moderately toxic by inhalation
and intraperitoneal routes. A skin and severe
eye irritant. A dangerous fire hazard when
exposed to heat or flame. Explosive in the
form of vapor when exposed to heat or
flame. When heated to decomposition it
emits acrid smoke and irritating fumes.
