Is P-Xylene flammable?

ICSC 0086 – p-XYLENE. Flammable. Above 27°C explosive vapour/air mixtures may be formed. NO open flames, NO sparks and NO smoking.

Is P-Xylene volatile?

At 20 0C , para-xylene (p-xylene) is a liquid that floats on water and is moderately volatile.

Is P-xylene reactive?

Highly flammable. Insoluble in water. P-XYLENE may react with oxidizing materials.

Is xylene and paint thinner the same?

They include mineral spirits (informally referred to as “paint thinner”), naphtha, toluene, xylene and some “turpentine substitutes” such as turpatine and T.R.P.S. Their primary use in wood finishing is for thinning waxes, oils, and varnishes, including polyurethane varnish, and for cleaning brushes.

Why is P Xylene important?

p-Xylene is an important chemical feedstock. Among other industrial applications, it is a raw material in the large scale synthesis of various polymers. In particular it is a component in the production of terephthalic acid for polyesters such as polyethylene terephthalate (generally known as PET).

What is P Xylene used for?

Paraxylene is widely used as a feedstock (or “building block”) to manufacture other industrial chemicals, notably terephthalic acid (TPA), purified terephthalic acid (PTA) and dimethyl-terephthalate (DMT). TPA, PTA and DMT are used to manufacture polyethylene terephthalate (PET) polyesters, a kind of plastic.

What is the purpose of xylene?

It is primarily used as a solvent (a liquid that can dissolve other substances) in the printing, rubber, and leather industries. Along with other solvents, xylene is also widely used as a cleaning agent, a thinner for paint, and in varnishes.

Is xylene stronger than acetone?

The key difference between xylene and acetone is that xylene is a cheap and less toxic solvent, whereas acetone is an expensive and more toxic solvent. Both xylene and acetone are important as solvents in chemistry laboratories.

How is the melting point of p-xylene determined?

Production. The p -xylene is then separated out in a series of distillation, adsorption or crystallization and reaction processes from the m -xylene, o -xylene, and ethylbenzene. Its melting point is the highest among this series of isomers, but simple crystallization does not allow easy purification due to the formation of eutectic mixtures.

What are the effects of p-xylene on the body?

Behavior in Fire: Vapor is heavier than air and may travel considerable distance to a source of ignition and flash back. (USCG, 1999) Vapors cause headache and dizziness. Liquid irritates eyes and skin. If taken into lungs, causes severe coughing, distress, and rapidly developing pulmonary edema.

How is the p-xylene in naphtha produced?

p-Xylene is produced by catalytic reforming of petroleum naphtha as part of the BTX aromatics (benzene, toluene and the xylene isomers) extracted from the catalytic reformate. The p -xylene is then separated out in a series of distillation, adsorption or crystallization and reaction processes from the m -xylene, o -xylene, and ethylbenzene .

How is p-xylene different from the other isomers?

It is in the positions of the two methyl groups, their arene substitution pattern, that it differs from the other isomers, o -xylene and m -xylene. All have the same chemical formula C 6 H 4 (CH 3) 2. All xylene isomers are colorless and highly flammable. The odor threshold of p -xylene is 0.62 parts per million (ppm).
