Mga gamit ng toluene sa industriya

Ang toluene o methylbenzene ay clear at walang kulay na liquid na matamis-matalim ang amoy. Mahina itong humalo sa tubig, mahusay na organic solvent at flammable. Ginagawa ito mula petroleum aromatic stream at coal processing.

Ano ang toluene?

Ginagamit ito dahil sa solvency, volatility at papel sa organic synthesis. Humahalo sa maraming organic solvent at tinutunaw ang resin, oil, rubber, ilang polymer at paint component.

Hindi ito ligtas na ordinaryong household solvent. Mapanganib ang vapor sa paglanghap at irritating sa balat at mata; maaaring magdulot ng hilo, coordination problem at nervous-system damage ang mataas na concentration. Kailangan ang ventilation, fire control at PPE.

Mga gamit sa industriya

• Component at feedstock ng aromatic petroleum product, benzene, xylene at high-octane fuel component.
• Solvent at thinner para sa varnish, enamel, paint, primer, adhesive at resin.
• Printing ink, process solvent at packaging adhesive.
• Road at marking paint na nangangailangan ng tamang viscosity at drying rate.
• Organic synthesis ng benzoic acid, benzaldehyde, benzyl chloride, nitrotoluene at iba pa.
• Toluene diisocyanate (TDI) para sa polyurethane foam, elastomer at coating.
• Nitration para sa explosive, kabilang ang industrial TNT.
• Nitrocellulose varnish, enamel at blended solvent.
• Ilang pharmaceutical at cosmetic process bilang controlled process solvent.
• Fuel at petrochemical aromatic fraction at chemical feedstock.

Solvent at thinner

Tinutunaw o dini-dilute nito ang resin, rubber, polystyrene, vinyl at acrylic polymer, binabagay ang flow at application at evaporation rate.

Maaari itong bahagi ng blended solvent, ngunit hindi universal substitute. Nakadepende ang compatibility sa varnish, paint, adhesive o polymer. Maaaring baguhin ng maling kapalit ang drying, adhesion, gloss, coating strength at safety.

Kaligtasan at storage

Itago sa sealed container, malayo sa apoy, spark at init. Kailangan ang ventilation, glove, eye protection at manufacturer instruction. Huwag gamitin sa saradong lugar nang walang exhaust.

Para sa kalkulasyon, tingnan ang densidad at bigat ng toluene.
