25013-15-4 Usage
Description
METHYLSTYRENE, also known as Vinyltoluene Monomer, is a clear colorless liquid with an aromatic odor. It has a flash point of 130°F and a density of 7.5 lb/gal. METHYLSTYRENE is insoluble in water and may polymerize exothermically if heated or contaminated. The inhibitor usually used is tert-butyl catechol. Its vapors are heavier than air, and it is characterized by a strong, disagreeable odor with an odor threshold of 50 ppm. METHYLSTYRENE is a combustible chemical and is very slightly soluble in water but soluble in methanol and ether.
Uses
Used in Polymer and Coatings Industry:
METHYLSTYRENE is used as a reactive monomer for the production of polymers and coatings. Its reactive nature allows it to be polymerized to form various types of polymers, which are then used in the manufacturing of coatings and other related products.
Used in Pharmaceutical Industry:
METHYLSTYRENE, specifically as a Vinyltoluene Monomer (mand pmixture) stabilized with TBC, can be used to treat inflammation. Its anti-inflammatory properties make it a valuable component in the development of pharmaceutical products aimed at reducing inflammation and related discomfort.
Used as a Solvent:
Due to its solubility in methanol and ether, METHYLSTYRENE is also used as a solvent in various chemical processes. Its ability to dissolve other substances makes it a useful component in the production of various chemicals and materials.
Air & Water Reactions
Flammable. Insoluble in water.
Reactivity Profile
METHYLSTYRENE polymerizes readily and exothermically [Handling Chemicals Safely 1980. p. 961].
Health Hazard
LIQUID: Irritating to skin and eyes. Harmful if swallowed.
Flammability and Explosibility
Notclassified
Chemical Reactivity
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).
Safety Profile
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.
Potential Exposure
(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.
Carcinogenicity
The IARC has determined that there is
evidence suggesting the lack of carcinogenicity of vinyltoluene in experimental animals and
inadequate evidence in humans.
Shipping
UN2618 Vinyltoluenes, stabilized, Hazard Class:
3; Labels: 3-Flammable liquid.
Incompatibilities
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.
Waste Disposal
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.
Check Digit Verification of cas no
The CAS Registry Mumber 25013-15-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,5,0,1 and 3 respectively; the second part has 2 digits, 1 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 25013-15:
(7*2)+(6*5)+(5*0)+(4*1)+(3*3)+(2*1)+(1*5)=64
64 % 10 = 4
So 25013-15-4 is a valid CAS Registry Number.
