What happens if you inhale cyclohexane?
Breathing in large amounts of cyclohexane vapours can cause headaches, dizziness, drowsiness, incoordination and euphoria. Ingestion of cyclohexane may cause stomach upset. These effects are not likely to occur at levels of cyclohexane that are normally found in the environment.
Is toluene banned in the US?
Toluene is known as part of the so-called “toxic trio” of dangerous chemicals found in polishes, including formaldehyde, a preservative, and dibutyl phthalate, which gives polish a hard finish. The trio is banned in many foreign countries but is legal in the U.S. if it is listed on the ingredient list.
What is heptane used for in everyday life?
Heptane liquid is consistently ranked among the most useful industrial chemicals because of its ideal chemical properties. Among many other applications, heptane is used for anesthetics, cements, compounders, inks, lab reagents, organic synthesis and solvents.
What products contain heptane?
Heptane is found in rubber cement, outdoor stove fuel, and in paint coatings. Printer ink bought in stores also contains Heptane–solvents like Heptane are common in types of ink, because they suspend the dye and help contribute to the final product being smooth, glossy, and long lasting.

What is the color of 2 6 diaminotoluene?
2,6-diaminotoluene is a colorless prisms (from water ). (NTP, 1992) 2,6-diaminotoluene is a diamine that is toluene in which both of the hydrogens ortho- to the methyl group are replaced by amino groups.
Is 2 6 diaminotoluene harmful to the environment?
2,6-Diaminotoluene’s production and use in the manufacture of dyes and dye intermediates may result in its release to the environment through various waste streams. If released to air, a vapor pressure of 2.46X10-3 mm Hg at 25 °C indicates 2,6-diaminotoluene will exist solely as a vapor in the atmosphere.
What are the side effects of diaminotoluene?
In human beings, as in animals, diaminotoluenes are considered to be irritants for the mucous membranes and skin, and to lead to conjunctivitis and corneal opacities. In the case of ingestion of massive amounts, nausea, vomiting, and diarrhea would occur, with the possible production of methemoglobinemia. /Diaminotoluene/
What is the half life of 2 6 diaminotoluene in air?
Vapor-phase 2,6-diaminotoluene will be degraded in the atmosphere by reaction with photochemically-produced hydroxyl radicals; the half-life for this reaction in air is estimated to be 0.6 hours. By analogy to 2,4-diaminotoluene which absorbs UV wavelength 294 nm, 2,6-diaminotoluene may be susceptible to direct photolysis by sunlight.
