Styrene monomer -Properties

Colorless oily liquid with aromatic odor. The freezing point is -30.6 ℃. Boiling point 145 ℃. Relative density 0.9051. Flash point (open cup) 31. 11 ℃. Self-ignition point 490 ℃. Refractive index 1. 5467. Viscosity (20 ℃)0.763mPa -s. Slightly soluble in water, soluble in ethanol, ether, methanol, acetone and carbon disulfide. Easily polymerize when heated or exposed to sunlight, or in the presence of peroxides, releasing heat during polymerization, and can cause an explosion. Explosion limit 1. 1% ~ 6. 1% (volume).

Styrene monomer -preparation

Ethylbenzene as raw material, in the three iron oxide (or aluminum) based T-315 platinum catalyst, at 550~560 ℃ temperature, dehydrogenation of styrene, and then by distillation, purified 99. 5% of the fine styrene.

Styrene monomer -Uses

This product is mainly used for polystyrene, styrene butadiene rubber engineering plastics (such as ABS, AAS, etc.), ion exchange resin, medicine and other raw materials.

Styrene monomer -Safety

This product is poisonous. Weak toxicity than benzene. Styrene has a funny odor, which can be clearly detected at 25 x 10 -6. At 50 × 10-6, it will feel unpleasant, but at this concentration, there is no toxic effect. With the increase of concentration, the irritation is enhanced, which can stimulate the skin and respiratory tract. Gastric mucosa is irritated when eating in a poorly ventilated room. Styrene, unlike benzene, does not cause chronic poisoning, because styrene is easily oxidized into benzoic acid, phenyl glycol, mandelic acid, etc. in vivo, and then becomes hippuric acid or gluconate and is excreted. The maximum allowable concentration in air is 420mg/m3. The production equipment shall be sealed to prevent running, emitting, dripping and leakage. Pay attention to personal protection and wear personal protective equipment when working. The operator shall conduct regular inspection. Those with respiratory diseases, liver diseases, kidney diseases or blood diseases should not be engaged in this operation.
with galvanized iron drum packaging, packaging when adding polymerization inhibitor, stored in low temperature (below 25 ℃) or refrigerated warehouse, to prevent polymerization deterioration. Keep away from fire sources and do not expose to direct sunlight. The storage period is one month. Storage and transportation shall be in accordance with the provisions for flammable and toxic substances.
