| Hazard Information | Back Directory | [General Description]
A colorless liquid. | [Reactivity Profile]
ETHYL CYCLOHEXANE(1678-91-7) may be incompatible with strong oxidizing agents such as nitric acid. Charring may occur followed by ignition of unreacted hydrocarbon and other nearby combustibles. In other settings mostly unreactive. Not affected by aqueous solutions of acids, alkalis, most oxidizing agents, and most reducing agents. When heated sufficiently or when ignited in the presence of air, oxygen or strong oxidizing agents, burns exothermically to produce carbon dioxide and water. | [Air & Water Reactions]
Highly flammable. | [Hazard]
Flammable, moderate fire risk; flammable
limits in air 0.9–6.6%. | [Health Hazard]
Diziness, with nausea and vomiting. Concentrated vapor may cause collapse and unconsciousness. | [Chemical Properties]

Ethylcyclohexane [1678-91-7] M 112.2, b 131.2o/742mm, d 4 0.7839, n D 1.43304, n D 1.43073. Purify it by azeotropic distillation with 2-ethoxyethanol; then the alcohol is washed out with water and, after drying, the ethylcyclohexane is redistilled. The dried material has been repeatedly fractionated over Na. [Baker & Groves J Chem Soc 1148 1939, Beilstein 5 H 35, 5 III 90, 5 IV 115.] |
