C6H14

The complete combustion requires 1.527×1024molecules O2 . There are four steps to follow in this problem: Balance the equation. Use the molar mass of hexane to calculate the moles of hexane.

Mass of oxygen required = 19.5 moles × 16 g/mol = 312 g. Hence, 312 grams of oxygen is essentially required for complete combustion of 3 moles of butane gas.

8mol

The combustion of hexane (C6H14) is represented in the balanced equation : 2 C6H14 + 19 O — 12 CO2 + 14 H2O MM hexane 86.18 g/mole, O2 32 g/mole, CO2 44 g/ mole, H2O 18 g/mole A. If 45 g of hexane is reacted and 45 g of water is recovered.

Acute (short-term) inhalation exposure of humans to high levels of hexane causes mild central nervous system (CNS) effects, including dizziness, giddiness, slight nausea, and headache.

EMERGENCY PROCEDURES

1. Eye exposure: If xylene or a solution containing xylene gets into the eyes, immediately flush the eyes with large amounts of water for a minimum of 15 min, lifting the lower and upper lids occasionally.
2. Skin exposure: The contaminated skin should be washed with soap and water for at least 15 min.

Results of studies in animals indicate that large amounts of xylene can cause changes in the liver and harmful effects on the kidneys, lungs, heart, and nervous system.

What Personal Protective Equipment (PPE) is needed when working with xylene? Eye/Face Protection: Wear chemical safety goggles. A face shield (with safety goggles) may also be necessary. Skin Protection: Wear chemical protective clothing e.g. gloves, aprons, boots.

Carrot oil, Olive oil, Pine oil, Rose oil, are not only bio friendly and economical but can also be used as clearing agent instead of xylene.

In keeping with the general rule of thumb that like dissolves like, however, xylene is very good at dissolving other oily compounds that are poorly soluble in water. This makes it an excellent solvent for hydrocarbons and many hydrophobic or water-insoluble compounds like greases and various pesticides and herbicides.

The mineral spirits left after the toluene and xylene are removed is sold as “odorless” mineral spirits….Understanding Solvents: Part I.

Generally, mineral spirits and paint thinner are interchangeable products. Mineral spirits sometimes is lower in odor than paint thinners.

Turpentine has more solvency than mineral spirits. Most painters prefer it as a paint thinner because it costs less, is not so sticky and has a less offensive odor than turpentine. Still, mineral spirits do have an odor that some people may find unpleasant. They may prefer to use odorless paint thinner.

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.

Acetone can be used to take off nail polish, paints or even lacquers. Xylene can be used for making histological preparations, and certain plastics. It can also be used as a solvent and cleaning agent.

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.

While acetone has a wide array of uses such as the preparation of metal before painting, thinning polyester resin, dissolving superglue, removing nail varnishes, removing rosin flux to prevent the rusty bolt effect as well as in the pharmaceutical industries, paint thinner is commonly used to remove any type of paint …

The basic difference between a thinner and turpentine is that the thinner is a liquid mostly used for thinning the consistency of another liquid while turpentine is a kind of volatile essential oil (extracted from the pine trees wood by steam distillation) used as a solvent and paint thinner.

Turpentine was still faster on both. Acetone looked to be the fastest; significantly speedier than the turpentine, and fastest on the Gugolz.

Acetone is perfect for cleaning and removing thick hardened paint, but you cannot mix acetone with paint and still use it. Paint thinner is better for cleaning wet paint, though it will remove dried paint slowly if you soak it.
