(E)-hept-3-ene - Introduction
TRANS-3-HEPTENE is a hydrocarbon compound with a chemical formula of C7H14 and a structural formula of CH3CH = CHCH2CH2CH2CH3. It is a colorless liquid with a special smell. The following is a description of the nature, use, preparation and safety information of the TRANS-3-HEPTENE:
Nature:
- TRANS-3-HEPTENE is a water-insoluble liquid with a low vapor pressure at room temperature.
-It is soluble in non-polar solvents, such as petroleum ether and benzene, but almost insoluble in polar solvents, such as water and alcohol.
-The density of the TRANS-3-HEPTENE is relatively high, the boiling point is 99-102 ° C, and the ignition point is -9 ° C.
Use:
- TRANS-3-HEPTENE are often used as important intermediates in organic synthesis.
-It can be used to synthesize biologically active compounds, such as medicines, pesticides and spices.
- TRANS-3-HEPTENE can also be used as a raw material for lubricants and detergents.
Method:
- TRANS-3-HEPTENE can be prepared by a variety of methods, one of which is commonly used by acid-catalyzed isomerization of butyraldehyde.
-In the reaction, butyraldehyde undergoes intramolecular rearrangement under the catalysis of acid to generate TRANS-3-HEPTENE.
Safety Information:
- TRANS-3-HEPTENE on the skin, eyes and mucous membranes irritant, need to pay attention to protection.
-It is a flammable liquid and should be kept away from open flames and high temperatures.
-Good ventilation conditions should be maintained during use to prevent the accumulation of vapor.
