ビニルトルエン (モノマー) (m-, p-混合物) 化学特性,用途語,生産方法
外観
無色～ほとんど無色透明液体
用途
塗料用改質剤、絶縁強化剤、医薬品、農薬中間体
化学的特性
Colourless liquid with a strong and unpleasant odour. Very slightly soluble in water; soluble in methanol, ether. Combustible.
使用
Solvent, intermediate.
一般的な説明
A clear colorless liquid with an aromatic odor. Flash point 130°F. Density 7.5 lb /gal. Insoluble in water. May polymerize exothermically if heated or contaminated. If polymerization takes place inside a container, the container may rupture violently. Inhibitor is usually tert-butyl catechol. Vapors heavier than air. Used as a solvent and to make other chemicals.
空気と水の反応
Flammable. Insoluble in water.
反応プロフィール
METHYLSTYRENE polymerizes readily and exothermically [Handling Chemicals Safely 1980. p. 961].
健康ハザード
LIQUID: Irritating to skin and eyes. Harmful if swallowed.
化学反応性
Reactivity with Water No reaction; Reactivity with Common Materials: No reactions; Stability During Transport: Stable; Neutralizing Agents for Acids and Caustics: Not pertinent; Polymerization: Slow at ordinary temperatures but when hot may rupture container. Also polymerized by metal salts such as those of iron or aluminum; Inhibitor of Polymerization: Tertiary Butylcatechol (typically 10 to 50 ppm).
安全性プロファイル
Moderately toxic by
ingestion and inhalation. An experimental
teratogen. Human systemic effects by
inhalation: eye and olfactory effects.
Experimental reproductive effects. Mutation
data reported. A skin and eye irritant.
Flammable when exposed to heat or flame;
can react vigorously with oxidrzing
materials. When heated to decomposition it
emits acrid smoke and irritating fumes.
職業ばく露
(mixed isomers): Vinyl toluene is
used in copolymers and as specialty monomer for paint,
varnish, and polyester preparations; as a solvent and an
organic intermediate.
発がん性
The IARC has determined that there is
evidence suggesting the lack of carcinogenicity of vinyltoluene in experimental animals and
inadequate evidence in humans.
輸送方法
UN2618 Vinyltoluenes, stabilized, Hazard Class:
3; Labels: 3-Flammable liquid.
不和合性
Vapors may form explosive mixture
with air. Violent reaction with oxidizers (chlorates,
nitrates, peroxides, permanganates, perchlorates, chlorine,
bromine, fluorine, etc.); contact may cause fires or
explosions. Keep away from alkaline materials, strong
bases, strong acids, oxoacids, epoxides, catalysts for vinyl
polymerization, such as peroxides, strong acids; iron or
aluminum salts. Usually inhibited with tert-butylcatechol
to prevent polymerization.
廃棄物の処理
Dissolve or mix the material
with a combustible solvent and burn in a chemical incinerator
equipped with an afterburner and scrubber. All federal,
state, and local environmental regulations must be
observed.
